+2007-04-02, Version 4.0.0
+ * collectd: The plugin-infrastructure has been changed to allow for
+ more types of plugins, namely `write' and `log' plugins.
+ * collectd: The read-function has been changed to read many plugins in
+ parallel, using threads. Thus, plugins generally need to use
+ thread-safe functions from now on.
+ * collectd: The '-t' command line options allows to perform syntax tests
+ of the configuration file and exit immediately.
+ * csv plugin: The new `csv' plugin handles output to `comma separated
+ values'-files.
+ * rrdtool plugin: The new `rrdtool' plugin handles output to
+ RRD-files. Data can be cached to combine multiple updates into one
+ write to increase IO-performance.
+ * network plugin: The new `network' plugin handles IO via the network.
+ It implements a different, much more extensible protocol which can
+ combine many values in one packet, decreasing the number of UDP-
+ packets being sent. It can read from and send to the network and
+ with the appropriate configuration even forward packets to other
+ networks.
+ * unixsock plugin: The new `unixsock' plugin provides an interface to
+ communicate with the daemon while it is running. Right now the
+ commands `GETVAL' and `PUTVAL' are implemented, but more are to
+ come.
+ * perl plugin: The new `perl' plugin allows you to write extensions
+ for collectd in the scripting-language Perl.
+ * logfile plugin: The new `logfile' plugin writes logmessages to files
+ or STDOUT or STDERR.
+ * syslog plugin: The new `syslog' plugin sends logmessages to the
+ system's syslog daemon.
+ * entropy plugin: The new `entropy' plugin collects the amount of
+ entropy currently being available to the system.
+ * exec plugin: The new `exec' plugin forks child processes and reads
+ back values provided by the forked processes.
+ * iptables plugin: The new `iptables' plugin reads counters from
+ iptables rules. Thanks to Sjoerd van der Berg for contributing this
+ plugin.
+ * irq plugin: The new `irq' plugin collects the IRQ-counters. Thanks
+ to Peter Holik for contributing this plugin.
+ * nut plugin: The new `nut' plugin connects the upsd of the `network
+ ups tools' and reads information about the connected UPS.
+ * apache plugin: Support for lighttpd's `BusyServers' (aka.
+ connections) field was added by Florent Monbillard.
+ * collectd-nagios: The new `collectd-nagios' binary queries values
+ from collectd, parses them and exits according to Nagios-standards.
+
2007-05-29, Version 3.11.5
* configure: Added `AC_SYS_LARGEFILE' for LFS.
* ntpd plugin: Fix a potential buffer overflow.

+
+ * Output can be written or send to various destinations by the following
+ plugins:
+
+ - csv
+ Write to comma seperated values (CSV) files. This needs lots of
+ diskspace but is extremely portable and can be analysed with almost
+ every program that can analyse anything. Even Microsoft's Excel..
+
+ - network
+ Send the data to a remote host to save the data somehow. This is useful
+ for large setups where the data should be saved by a dedicated machine.
+
+ - perl
+ Of course the values are propagated to plugins written in Perl, too, so
+ you can easily do weird stuff with the plugins we didn't dare think of
+ ;) See collectd-perl(5).
+
+ - rrdtool
+ Output to round-robin-database (RRD) files using librrd. See rrdtool(1).
+ This is likely the most popular destination for such values. Since
+ updates to RRD-files are somewhat expensive this plugin can cache
+ updates to the files and write a bunch of updates at once, which lessens
+ system load a lot.
+
+ - unixsock
+ One can query the values from the unixsock plugin whenever they're
+ needed. Please read collectd-unixsock(5) for a description on how that's
+ done.
+
+ * Logging is, as everything in collectd, provided by plugins. The following
+ plugins keep up informed about what's going on:
+
+ - logfile
+ Writes logmessages to a file or STDOUT/STDERR.
+
+ - syslog
+ Logs to the standard UNIX logging mechanismn, syslog.
+
+ * Performance: Since collectd is running as a daemon it doesn't spend much
+ time starting up again and again. With the exception of the exec plugin no
+ processes are forked. Caching in output plugins, such as the rrdtool and
+ network plugins, makes sure your resources are used efficiently. Also,
+ since collectd is programmed multithreaded it benefits from hyperthreading
+ and multicore processors and makes sure that the daemon isn't idle if only
+ one plugins waits for an IO-operation to complete.
+
+ * Once set up, hardly any maintenence is neccessary. Setup is kept as easy
+ as possible and the default values should be okay for most users.
Operation
Run `collectd -h' for a list of builtin defaults. See `collectd.conf(5)'
for a list of options and a syntax description.
- * When running collectd writes system statistics in RRD-files. Per default
- they reside in `/var/lib/collectd'.
+ * When the `csv' or `rrdtool' plugins are loaded they'll write the values to
+ files. The usual place for these files is beneath `/var/lib/collectd'.
- * When using the `ping' plugin collectd needs to run as user root, since only
- root can craft ICMP packages needed to ping other hosts. collectd should
- NOT be installed setuid root since it can be used to overwrite valuable
- files..
+ * When using some of the plugins, collectd needs to run as user root, since only
+ root can do certain things, such as craft ICMP packages needed to ping
+ other hosts. collectd should NOT be installed setuid root since it can be
+ used to overwrite valuable files!
* Sample scripts to generate graphs reside in `contrib/' in the source
package or somewhere near `/usr/share/doc/collectd' in most distributions.
Please be aware that those script are meant as a starting point for your
own experiments.. Some of them require the `RRDs' Perl module.
- (`librrds-perl' on Debian)
+ (`librrds-perl' on Debian) If you have written a more sophisticated
+ solution please share it with us.
* The RRAs of the automatically created RRD files depend on the `step'
- and `heartbeat' settings given on compile time. For a list of the
- default RRAs take a look in the collectd(1) manpage.
+ and `heartbeat' settings given. If change these settings you may need to
+ re-create the files, losing all data. Please be aware of that when changing
+ the values and read the rrdtool(1) manpage thoroughly.
Prerequisites
* Usual suspects: C compiler, linker, preprocessor, make, ...
- * rrdtool (optional; headers and library; rrdtool 1.0 and 1.2 both work fine)
+ * A POSIX-threads (pthread) implementation.
+ Since gathering some statistics is slow (network connections, slow devices,
+ etc) the collectd is parellelized. The POSIX threads interface is being
+ used and should be found in various implementations for hopefully all
+ platforms.
+
+ * libcurl (optional)
+ If you want to use the `apache' plugin
+
+ * libiptc (optional)
+ For querying iptables counters.
+
+ * libmysqlclient (optional)
+
+ * liboping (optional, if not found a version shipped with this distribution
+ can be used)
+ Used by the `ping' plugin to send and receive ICMP packets.
+
+ * libpcap (optional)
+ Used to capture packets by the `dns' plugin.
+
+ * librrd (optional; headers and library; rrdtool 1.0 and 1.2 both work fine)
If built without `librrd' the resulting binary will be `client only', i.e.
will send it's values via multicast and not create any RRD files itself.
Alternatively you can chose to write CSV-files (Comma Seperated Values)
instead.
- * libmysqlclient (optional)
-
- * lm-sensors (optional)
+ * libsensors (optional)
+ To read from `lm_sensors'.
* libstatgrab may be used to collect statistics on systems other than Linux
and/or Solaris. Note that CPU- and disk-statistics, while being provided
by this library, are not supported in collectd right now..
<http://www.i-scream.org/libstatgrab/>
- * libcurl (optional)
- If you want to use the `apache' plugin
+ * libupsclient/nut (optional)
+ For the `nut' plugin which queries nut's `upsd'.
* librt, libsocket, libkstat, libdevinfo
Various standard Solaris libraries which provide system functions.
- * libpthread (optional)
- For parallelization, especially for plugins that communicate with the
- outside, e. g. with a socket.
-
* CoreFoundation.framework and IOKit.framework
- For copiling on darwin in general and the `apple_sensors' plugin in
+ For compiling on Darwin in general and the `apple_sensors' plugin in

-collectd is a small daemon written in C for performance. It reads various
-system statistics and updates RRD files, creating them if neccessary.
-Since the daemon doesn't need to startup every time it wants to update the
-files it's very fast and easy on the system. Also, the statistics are very
-fine grained since the files are updated every 10 seconds.

+=head1 NAME
+
+Collectd::Unixsock - Abstraction layer for accessing the functionality by collectd's unixsock plugin.
+
+=head1 SYNOPSIS
+
+ use Collectd::Unixsock ();
+
+ my $sock = Collectd::Unixsock->new ($path);
+
+ my $value = $sock->getval (%identifier);
+ $sock->putval (%identifier,
+ time => time (),
+ values => [123, 234, 345]);
+
+ $sock->destroy ();
+
+=head1 DESCRIPTION
+
+collectd's unixsock plugin allows external programs to access the values it has
+collected or received and to submit own values. This Perl-module is simply a
+little abstraction layer over this interface to make it even easier for
+programmers to interact with the daemon.

+
+=head1 VALUE IDENTIFIER
+
+The values in the collectd are identified using an five-tupel (host, plugin,
+plugin-instance, type, type-instance) where only plugin-instance and
+type-instance may be NULL (or undefined). Many functions expect an
+I<%identifier> hash that has at least the members B<host>, B<plugin>, and
+B<type>, possibly completed by B<plugin_instance> and B<type_instance>.
+
+Usually you can pass this hash as follows:
+
+ $obj->method (host => $host, plugin => $plugin, type => $type, %other_args);
+

+=head1 PUBLIC METHODS
+
+=over 4
+
+=item I<$obj> = Collectd::Unixsock->B<new> ([I<$path>]);
+
+Creates a new connection to the daemon. The optional I<$path> argument gives
+the path to the UNIX socket of the C<unixsock plugin> and defaults to
+F</var/run/collectd-unixsock>. Returns the newly created object on success and
+false on error.

+} # new
+
+=item I<$res> = I<$obj>-E<gt>B<getval> (I<%identifier>);
+
+Requests a value-list from the daemon. On success a hash-ref is returned with
+the name of each data-source as the key and the according value as, well, the
+value. On error false is returned.

+=item I<$obj>-E<gt>B<putval> (I<%identifier>, B<time> => I<$time>, B<values> => [...]);
+
+Submits a value-list to the daemon. If the B<time> argument is omitted
+C<time()> is used. The requierd argument B<values> is a reference to an array
+of values that is to be submitted. The number of values must match the number
+of values expected for the given B<type> (see L<VALUE IDENTIFIER>), though this
+is checked by the daemon, not the Perl module. Also, gauge data-sources
+(e.E<nbsp>g. system-load) may be C<undef>. Returns true upon success and false
+otherwise.

+ Perl modules to be used in conjunction with collectd. See the perldoc
+documentation of the .pm-files to find out what they're good for.
+
add_rra.sh
----------
Before version 3.9.0 collectd used to create a different set of RRAs. The
-most detailed of these old RRAs hat a one minute resolution. This script can be
-used to add three more RRAs: minimum, maximum and average with a ten second
+most detailed of these old RRAs hat a one minute resolution. This script can
+be used to add three more RRAs: minimum, maximum and average with a ten second
resolution and 2200 rows (~6 hours). This will make houly statistics much more
interesting. Please note that no sanity- checking whatsoever is performed. You
can seriously fuck up your RRD files if you don't know what you're doing.
`/var/lib/collectd/' and generate an HTML file and a directory containing
several PNG files which are graphs of the RRD files found.
-collectd.conf
--------------
- A sample config file. Used by the Debian package.
-
collection.cgi
--------------
Sample CGI script that creates graphs on the fly. The Perl module `RRDs' is
needed (Debian package `librrds-perl').
-init.d-rh7
-----------
- Sample init script. Used by the RPM specfile.
+extractDS.px
+------------
+ Creates a new RRD-file with only one data-source (DS) of the source-RRD-
+file. That is very handy when you realise that you have bundled up DSes in one
+RRD-file that should have been in multiple RRD-files instead. Is is used by
+`migrate-3-4.px' to split up the cpu-, nfs-, swap-files and possibly others.
+
+fedora/
+-------
+ Init-script and Spec-file that can be used when creating RPM-packages for
+Fedora.
+
+migrate-3-4.px
+--------------
+ Migration-script to ease the switch from version 3 to version 4. Many
+RRD-files are expected in a different place, some have been changed (DSes have
+been renamed) and others have bee split up into multiple files. This script
+prints a bash-script to STDOUT which should do most of the work for you. You
+may still need to do some things by hand, read `README.migration' for more
+details.

+%description
+collectd is a small daemon written in C for performance. It reads various
+system statistics and updates RRD files, creating them if neccessary.
+Since the daemon doesn't need to startup every time it wants to update the
+files it's very fast and easy on the system. Also, the statistics are very
+fine grained since the files are updated every 10 seconds.

+%description
+collectd is a small daemon written in C for performance. It reads various
+system statistics and updates RRD files, creating them if neccessary.
+Since the daemon doesn't need to startup every time it wants to update the
+files it's very fast and easy on the system. Also, the statistics are very
+fine grained since the files are updated every 10 seconds.

+ LoadPlugin email
+ # ...
+ <Plugin email>
+ SocketGroup "collectd"
+ SocketPerms "0770"
+ MaxConns 5
+ </Plugin>
+
+=head1 DESCRIPTION
+
+The C<email plugin> opens an UNIX-socket over which one can submit email
+statistics, such as the number of "ham", "spam", "virus", etc. mails
+received/handled, spam scores and matched spam checks.
+
+This plugin is intended to be used with the
+L<Mail::SpamAssassin::Plugin::Collectd> SpamAssassin-plugin which is included
+in F<contrib/>, but is of course not limited to that use.
+
+=head1 OPERATION
+
+This plugin collects data indirectly by providing a UNIX-socket that external
+programs can connect to. A simple line based protocol is used to communicate
+with the plugin:
+
+=over 4
+
+=item
+
+E-Mail type (e.g. "ham", "spam", "virus", ...) and size (bytes):
+
+ e:<type>:<size>
+
+If C<size> is less than or equal to zero, C<size> is ignored.
+
+=item
+
+Spam score:
+
+ s:<value>
+
+=item
+
+Successful spam checks (e.g. "BAYES_99", "SUBJECT_DRUG_GAP_C", ...):
+
+ c:<type1>[,<type2>,...]
+
+Each line is limited to 256 characters (including the newline character).
+Longer lines will be ignored.

+
+collectd-exec - Documentation of collectd's C<exec plugin>
+
+=head1 SYNOPSIS
+
+ # See collectd.conf(5)
+ LoadPlugin exec
+ # ...
+ <Plugin exec>
+ Exec myuser myprog
+ Exec otheruser /path/to/another/binary
+ </Plugin>
+
+=head1 DESCRIPTION
+
+The C<exec plugin> forks of an executable and reads back values that it writes
+to C<STDOUT>. The executable is forked in a fassion similar to L<init>: It is
+forked once and not again until it exits. If it exited, it will be forked again
+after at most I<Interval> seconds. It is perfectly legal for the executable to
+run for a long time and continuously write values to C<STDOUT>.
+
+If you want/need better performance or more functionality you should take a
+long look at the C<perl plugin>, L<collectd-perl(5)>.
+
+=head1 DATA FORMAT
+
+The forked executable is expected to print values to C<STDOUT>. The expected
+format is as follows:
+
+=over 4
+
+=item
+
+Each line beginning with a C<#> (hash mark) is ignored.
+
+=item
+
+Any other line must be of the form C<I<type>,I<type-instance>,I<value>>, where
+I<type> is either B<counter> or B<gauge>, I<type-instance> may not contain
+C<,> (comma), C</> (slash) and C<\0> (null byte) and I<value> is either an
+integer (if I<type> is B<counter>) or a floating-point number (if I<type> is
+B<gauge>).
+
+=back
+
+The values are always considered to be "fresh", i.E<nbsp>e. the time is set to
+"now".
+
+When collectd exits it sends a B<SIGTERM> to all still running
+child-processes upon which they have to quit.
+
+=head1 CAVEATS
+
+=over 4
+
+=item
+
+If the executable only writes one value and then exits I will be executed every
+I<Interval> seconds. If I<Interval> is short (the default is 10 seconds) this
+may result in serious system load.
+
+=item
+
+The user, the binary is executed as, may not have root privileges, i.E<nbsp>e.
+must have an UID that is non-zero.

+=head1 NAME
+
+collectd-nagios - Nagios plugin for querying collectd
+
+=head1 SYNOPSIS
+
+collectd-nagios B<-s> I<socket> B<-n> I<value_spec> B<-H> I<hostname> I<[options]>
+
+=head1 DESCRIPTION
+
+This small program is the glue between collectd and nagios. collectd collects
+various performance statistics which is provides via the C<unixsock plugin>,
+see L<collectd-unixsock(5)>. This program is called by Nagios, connects to the
+UNIX socket and reads the values from collectd. It then returns B<OKAY>,
+B<WARNING> or B<CRITICAL> depending on the values and the ranges provided by
+Nagios.
+
+=head1 ARGUMENTS AND OPTIONS
+
+The following arguments and options are required and understood by
+collectd-nagios. The order of the arguments generally doesn't matter, as long
+as no argument is passed more than once.
+
+=over 4
+
+=item B<-s> I<socket>
+
+Path of the UNIX socket opened by collectd's C<unixsock plugin>.
+
+=item B<-n> I<value_spec>
+
+The value to read from collectd. The argument is in the form
+C<plugin[-instance]/type[-instance]>.
+
+=item B<-H> I<hostname>
+
+Hostname to query the values for.
+
+=item B<-d> I<data_source>
+
+Each I<value_spec> may be made of multiple "data sources". With this option you
+can select one or more data sources. To select multiple data sources simply
+specify this option again. If multiple data sources are examined they are
+handled according to the consolidation function given with the B<-g> option.
+
+=item B<-g> B<none>I<|>B<average>I<|>B<sum>
+
+When multiple data sources are selected from a value spec they can be handled
+differently dependin on this option. The values of the following meaning:
+
+=over 4
+
+=item B<none>
+
+No consolidation if done and the warning and critical regions are applied to
+each value independently.
+
+=item B<average>
+
+The warning and critical ranges are applied to the average of all values.
+
+=item B<sum>
+
+The warning and critical ranges are applied to the sum of all values.
+
+=back
+
+=item B<-c> I<range>
+
+=item B<-w> I<range>
+
+Set the critical (B<-c>) and warning (B<-w>) ranges. These options mostly
+follow the normal syntax of Nagios plugins. The general format is
+"I<min>B<:>I<max>". If a value if smaller than I<min> or bigger than I<max> a
+warning or critical is returned, otherwise okay is returned. I<min> (and the
+colon) may be omitted and are then assumed to be zero. If I<max> (but not the
+colon) is omitted I<max> is set to positive infinity. If either I<min> or
+I<max> if set to B<~> they are set to negative and positive infinity,
+respectively.
+
+=back
+
+=head1 RETURN VALUE
+
+As usual for Nagios plugins this program writes a short, one line status
+message to STDOUT and signals success or failure with it's return value. It
+exists with a return value of B<0> for success or B<1> or B<2> for warning and
+critical, respectively. If the values is not available or some other error
+occured it returnes B<3> for "unknown".

+=head1 NAME
+
+collectd-perl - Documentation of collectd's C<perl plugin>
+
+=head1 SYNOPSIS
+
+ # See collectd.conf(5)
+ LoadPlugin perl
+ # ...
+ <Plugin perl>
+ IncludeDir "/path/to/perl/plugins"
+ BaseName "Collectd::Plugin"
+ LoadPlugin "FooBar"
+ </Plugin>
+
+=head1 DESCRIPTION
+
+The C<perl plugin> includes a Perl-interpreter in collectd and provides
+Perl-equivalents of the plugin-functions. This makes it possible to write
+plugins for collectd in Perl. This is a lot more performant than executing a
+Perl-script every time you want to read a value with the C<exec plugin> (see
+L<collectd-exec(5)>) and provides a lot more functionality, too.
+
+=head1 DATA TYPES
+
+There are two more complex types you need to know about:
+
+=over 4
+
+=item Data-Set
+
+A data-set is a list of one or more data-sources. Each data-source defines a
+name, type, min- and max-value and the data-set wraps them up into one
+structure. The general layout looks like this:
+
+ [{
+ name => 'data_source_name',
+ type => DS_TYPE_COUNTER || DS_TYPE_GAUGE
+ min => value || undef,
+ max => value || undef
+ }, ...]
+
+=item Value-List
+
+A value-list is one structure which features an array of values and fields to
+identify the values, i. e. time and host, plugin name and plugin-instance as
+well as a type and type-instance. Since the "type" is not included in the
+value-list but is passed as an extra argument, the general layout looks like
+this:
+
+ {
+ values => [123, 0.5],
+ time => time (),
+ host => 'localhost',
+ plugin => 'myplugin',
+ plugin_instance => '',
+ type_instance => ''
+ }
+
+=back
+
+=head1 METHODS
+
+The following functions provide the C-interface to Perl-modules. They are
+automatically exported into the module's namespace. You don't need to C<use>
+any special Modules to access them.
+
+=over 4
+
+=item B<plugin_register> (I<type>, I<name>, I<data>)
+
+Registers a callback-function or data-set.
+
+I<type> can be one of:
+
+=over 4
+
+=item TYPE_INIT
+
+=item TYPE_READ
+
+=item TYPE_WRITE
+
+=item TYPE_LOG
+
+=item TYPE_SHUTDOWN
+
+=item TYPE_DATASET
+
+=back
+
+I<name> is the name of the callback-function or the type of the data-set,
+depending on the value of I<type>. (Please note that the type of the data-set
+is the value passed as I<name> here and has nothing to do with the I<type>
+argument which simply tells B<plugin_register> what is being registered.)
+
+The last argument, I<data>, is either a function- or an array-reference. If
+I<type> is B<TYPE_DATASET>, then the I<data> argument must be an
+array-reference which points to an array of hashes. Each hash describes one
+data-source. For the exact layout see B<Data-Set> above.
+
+If the I<type> argument is any of the other types (B<TYPE_INIT>, B<TYPE_READ>,
+...) then I<data> is expected to be a function reference. These functions are
+called in the various stages of the daemon and are passed the following
+arguments:
+
+=over 4
+
+=item TYPE_INIT
+
+=item TYPE_READ
+
+=item TYPE_SHUTDOWN
+
+No arguments are passed
+
+=item TYPE_WRITE
+
+The arguments passed are I<type>, I<data-set>, and I<value-list>. I<type> is a
+string. For the layout of I<data-set> and I<value-list> see above.
+
+=item TYPE_LOG
+
+The arguments are I<log-level> and I<message>. The log level is small for
+important messages and high for less important messages. The least important
+level is B<LOG_DEBUG>, the most important level is B<LOG_ERR>. In between there
+are (from least to most important): B<LOG_INFO>, B<LOG_NOTICE>, and
+B<LOG_WARNING>. I<message> is simply a string B<without> a newline at the end.
+
+=back
+
+=item B<plugin_unregister> (I<type>, I<plugin>)
+
+Removes a callback or data-set from collectd's internal list of
+functionsE<nbsp>/ datasets.
+
+=item B<plugin_dispatch_values> (I<type>, I<value-list>)
+
+Submits a I<value-list> of type I<type> to the daemon. If the data-set I<type>
+is found (and the number of values matches the number of data-sources) then the
+type, data-set and value-list is passed to all write-callbacks that are
+registered with the daemon.
+
+=item B<plugin_log> (I<log-level>, I<message>)
+
+Submits a I<message> of level I<log-level> to collectd's logging mechanism.
+The message is passed to all log-callbacks that are registered with collectd.

+=head1 NAME
+
+collectd-unixsock - Documentation of collectd's C<unixsock plugin>
+
+=head1 SYNOPSIS
+
+ # See collectd.conf(5)
+ LoadPlugin unixsock
+ # ...
+ <Plugin unixsock>
+ SocketFile "/path/to/socket"
+ SocketGroup "collectd"
+ SocketPerms "0770"
+ </Plugin>
+
+=head1 DESCRIPTION
+
+The C<unixsock plugin> opens an UNIX-socket over which one can interact with
+the daemon. This can be used to use the values collected by collectd in other
+applications, such as monitoring, or submit externally collected values to
+collectd.
+
+This plugin is used by L<collectd-nagios(1)> to check if some value is in a
+certain range and exit with a Nagios-compatible exit code.
+
+=head1 COMMANDS
+
+Upon start the C<unixsock plugin> opens a UNIX-socket and waits for
+connections. Once a connection is established the client can send commands to
+the daemon which it will answer, if it understand them.
+
+The following commands are implemented:
+
+=over 4
+
+=item B<GETVAL> I<Identifier>
+
+If the value identified by I<Identifier> (see below) is found the complete
+value-list is returned. The response is a space seperated list of
+name-value-pairs:
+
+I<num> I<name>B<=>I<value>[ I<name>B<=>I<value>[ ...]]
+
+If I<num> is less then zero, an error occured. Otherwise it contains the
+number of values that follow. Each value is of the form I<name>B<=>I<value>.
+Counter-values are converted to a rate, e.E<nbsp>g. bytes per second.
+Undefined values are returned as B<NaN>.
+
+Example:
+ -> | GETVAL myhost/cpu-0/cpu-user
+ <- | 1 value=1.260000e+00
+
+=item B<PUTVAL> I<Identifier> I<Valuelist>
+
+Submits a value (identified by I<Identifier>, see below) to the daemon which
+will dispatch it to all it's write-plugins. The I<Valuelist> is a
+colon-seperated list of values, either an integer if the data-source is a
+counter, of a double if the data-source if of type "gauge". You can submit an
+undefined gauge-value by using B<U>. When submitting B<U> to a counter the
+behavior is undefined.
+
+Example:
+ -> | PUTVAL testhost/interface/if_octets-test0 1179574444:123:456
+ <- | 0 Success
+
+=back
+
+=head2 Identifiers
+
+Value or value-lists are identified in a uniform fassion:
+
+I<Hostname>/I<Plugin>/I<Type>
+
+Where I<Plugin> and I<Type> are both either of type "I<Name>" or
+"I<Name>-I<Instance>". This sounds more complicated than it is, so here are
+some examples:
+
+ myhost/cpu-0/cpu-user
+ myhost/load/load
+ myhost/memory/memory-used
+ myhost/disk-sda/disk_octets
+
+=head2 Return values
+
+Unless otherwise noted the plugin answers with a line of the following form:
+
+I<Num> I<Message>
+
+If I<Num> is zero the message indicates success, if I<Num> is non-zero the
+message indicates failure. I<Message> is a human-readable string that describes
+the return value further.
+
+Commands that return values may use I<Num> to return the number of values that
+follow, such as the B<GETVAL> command. These commands usually return a negative
+value on failure and never return zero.
+
+=head1 ABSTRACTION LAYER
+
+Shipped with the sourcecode comes the Perl-Module L<Collectd::Unixsock> which
+provides an abstraction layer over the actual socket connection. It can be
+found in the directory F<contrib/PerlLib>. If you want to use Perl to
+communicate with the daemon, you're encouraged to use and expand this module.

=head1 DESCRIPTION
This config file controls how the system statistics collection daemon
-B<collectd> behaves. The most significant options are B<Mode>, which controlls
-if the daemon will act as client, server or will be independent in local mode,
-and B<LoadPlugin> which controls which plugins to load.
+B<collectd> behaves. The most significant option is B<LoadPlugin>, which
+controls which plugins to load. These plugins ultimately define collectd's
+behavior.
The syntax of this config file is similar to the config file of the famos
B<Apache Webserver>. Each line containes either a key-value-pair or a
section-start or -end. Empty lines and everything after the hash-symbol `#' is
-ignored.
+ignored. Values are either string, enclosed in double-quotes,
+(floating-point-)numbers or a boolean extression, i.E<nbsp>e. either B<true> or
+B<false>. String containing of only alphanumeric characters and underscores do
+not need to be quoted.
=head1 GLOBAL OPTIONS
=over 4
-=item B<Mode> (B<Local>|B<Client>|B<Server>|B<Log>)
+=item B<BaseDir> I<Directory>
-Sets the operating mode. See the section B<MODES> in L<collectd(1)> for a
-description. This option determines which other options are allowed. Defaults
-to B<Local>.
+Sets the base directory. This is the directory beneath all RRD-files are
+created. Possibly more subdirectories are created. This is also the working
+directory for the daemon.
=item B<LoadPlugin> I<Plugin>
Loads the plugin I<Plugin>. There must be at least one such line or B<collectd>
-will be mostly useless. The names of the plugins are listed in L<collectd(1)>.
+will be mostly useless.
=item B<PIDFile> I<File>
Sets where to write the PID file to. This file is overwritten when it exists
and deleted when the program ist stopped. Some init-scripts might override this
-setting using the B<-P> commandline option. Available in B<all modes>.
-
-=item B<DataDir> I<Directory>
-
-Sets the data directory. This is the directory beneath all RRD-files are
-created. Possibly more subdirectories are created. This is also the working
-directory for the daemon. Available in B<all modes>, though the B<Client> mode
-won't write to this directory.
-
-=item B<LogFile> I<File>
+setting using the B<-P> commandline option.
-Sets the file to write debugging output to. This is only used if compiled with
-debugging enabled. It's ignored otherwise. Available in B<all modes>.
+=item B<PluginDir> I<Directory>
-=item B<Listen> I<Host> [I<Port>]
+Path to the plugins (shared objects) of collectd.
-=item B<Server> I<Host> [I<Port>]
+=item B<TypesDB> I<File>
-In B<client mode> the B<Server> statement sets the server to send datagrams to.
-The statement may occur multiple times to send each datagram to multiple
-destinations.
+Set the file that contains the data-set descriptions.
-In B<server mode> the B<Listen> statement sets the interfaces to bind to. When
-multiple statements are found the daemon will bind to multiple interfaces.
-
-The argument I<Host> may be a hostname, an IPv4 address or an IPv6 address. If
-the argument is a multicast address the daemon will join that multicast group.
-
-If no B<Listen> statement is found the server tries join both, the IPv6
-multicast group and the IPv4 multicast group. If no B<Server> statement is
-found the client will try to send data to the IPv6 multicast group first. If
-that failes the client will try the IPv4 multicast group.
-
-The default IPv6 multicast group is C<ff18::efc0:4a42>. The default IPv4
-multicast group is C<239.192.74.66>.
+=item B<Interval> I<Seconds>
-The optional I<Port> argument sets the port to use. It can either be given
-using a numeric port number or a service name. If the argument is omited the
-default port B<25826> is assumed.
+Configures the interval in which to query the read plugins. Obviously smaller
+values lead to a higher system load produces by collectd, while higher values
+lead to more coarse statistics.
-=item B<TimeToLive> I<1-255>
+=item B<ReadThreads> I<Num>
-Set the time-to-live of sent packets. This applies to all, unicast and
-multicast, and IPv4 and IPv6 packets. The default is to not change this value.
-That means that multicast packets will be sent with a TTL of C<1> (one) on most
-operating systems.
+Number of threads to start for reading plugins. The default value if B<5>, but
+you may want to increase this if you have more than five plugins that take a
+long time to read. Mostly those are plugin that do network-IO. Setting this to
+a value higher than the number of plugins you've loaded is totally useless.

=head1 PLUGIN OPTIONS
Some Plugins may register own options. These options must be inclosed in a
-C<Plugin>-Section. Which options exist depends on the plugin used:
+C<Plugin>-Section. Which options exist depends on the plugin used. Some plugins
+require external configuration, too. The C<apache plugin>, for example,
+required C<mod_status> to be configured in the webserver you're going to
+collect data from. These plugins are listed below as well, even if they don't
+require any configuration within collectd's configfile.
+
+A list of all plugins and a short summary for each plugin can be found in the
+F<README> file shipped with the sourcecode and hopefully binary packets as
+well.
=head2 Plugin C<apache>
</Location>
</IfModule>
+Since it's C<mod_status> module is very similar to Apache's, B<lighttpd> is
+also supported. It introduces a new field, called C<BusyServers>, to count the
+number of currently connected clients. This field is also supported.
+
The following options are accepted by the C<apache>-plugin:
=over 4
=back
+=head2 Plugin C<cpufreq>
+
+This plugin doesn't have any options. It reads
+F</sys/devices/system/cpu/cpu0/cpufreq/scaling_cur_freq> (for the first CPU
+installed) to get the current CPU frequency. If this file does not exist make
+sure B<cpufreqd> (L<http://cpufreqd.sourceforge.net/>) or a similar tool is
+installed and an "cpu governor" (that's a kernel module) is loaded.
+
+=head2 Plugin C<csv>
+
+=over 4
+
+=item B<DataDir> I<Directory>
+
+Set the directory to store RRD-files under. Per default RRD-files are generated
+beneath the daemon's working directory, i.E<nbsp>e. the B<BaseDir>.
+
+=back
+
=head2 Plugin C<df>

+=head2 Plugin C<exec>
+
+Please make sure to read L<collectd-exec(5)> before using this plugin. It
+contains valueable information on when the executable is executed and the
+output that is expected from it.
+
+=over 4
+
+=item B<Exec> I<User> I<Executable>
+
+Execute the executable I<Executable> as user I<User>.
+
+=back
+
=head2 Plugin C<hddtemp>
+To get values from B<hddtemp> collectd connects to B<localhost> (127.0.0.1),
+port B<7634/tcp>. The B<Host> and B<Port> options can be used to change these
+default values, see below. C<hddtemp> has to be running to work correctly. If
+C<hddtemp> is not running timeouts may appear which may interfere with other
+statistics..

+B<Host> and B<Port> options can be used to change these values, see below.
+C<mbmon> has to be running to work correctly. If C<mbmon> is not running
+timeouts may appear which may interfere with other statistics..
+
+C<mbmon> must be run with the -r option ("print TAG and Value format");
+Debian's F</etc/init.d/mbmon> script already does this, other people
+will need to ensure that this is the case.

=head2 Plugin C<mysql>
+The C<mysql plugin> requires B<mysqlclient> to be installed. It connects to the
+database when started and keeps the connection up as long as possible. When the
+connection is interrupted for whatever reason it will try to re-connect. The
+plugin logs loud complaints in case anything goes wrong.
+
+This plugin issues C<SHOW STATUS> and evaluates C<Bytes_{received,sent}>,
+C<Com_*> and C<Handler_*> which correspond to F<mysql_octets.rrd>,
+F<mysql_commands-*.rrd> and F<mysql_handler-*.rrd>. Also, the values of
+C<Qcache_*> are put in F<mysql_qcache.rrd> and values of C<Threads_*> are put
+in F<mysql_threads.rrd>. Please refer to the B<MySQL reference manual>,
+I<5.2.4. Server Status Variables> for an explanation of these values.
+
+Use the following options to configure the plugin:
+
=over 4
=item B<Host> I<Hostname>
=back
+=head2 Plugin C<network>
+
+=over 4
+
+=item B<Listen> I<Host> [I<Port>]
+
+=item B<Server> I<Host> [I<Port>]
+
+The B<Server> statement sets the server to send datagrams B<to>. The statement
+may occur multiple times to send each datagram to multiple destinations.
+
+The B<Listen> statement sets the interfaces to bind to. When multiple
+statements are found the daemon will bind to multiple interfaces.
+
+The argument I<Host> may be a hostname, an IPv4 address or an IPv6 address. If
+the argument is a multicast address the daemon will join that multicast group.
+
+If no B<Listen> statement is found the server tries join both, the default IPv6
+multicast group and the default IPv4 multicast group. If no B<Server> statement
+is found the client will try to send data to the IPv6 multicast group first. If
+that failes the client will try the IPv4 multicast group.
+
+The default IPv6 multicast group is C<ff18::efc0:4a42>. The default IPv4
+multicast group is C<239.192.74.66>.
+
+The optional I<Port> argument sets the port to use. It can either be given
+using a numeric port number or a service name. If the argument is omited the
+default port B<25826> is assumed.
+
+=item B<TimeToLive> I<1-255>
+
+Set the time-to-live of sent packets. This applies to all, unicast and
+multicast, and IPv4 and IPv6 packets. The default is to not change this value.
+That means that multicast packets will be sent with a TTL of C<1> (one) on most
+operating systems.
+
+=item B<Forward> I<true|false>
+
+If set to I<true>, write packets that were received via the network plugin to
+the sending sockets. This should only be activated when the B<Listen>- and
+B<Server>-statements differ. Otherwise packets may be send multiple times to
+the same multicast group. While this results in more network traffic than
+neccessary it's not a huge problem since the plugin has a duplicate detection,
+so the values will not loop.
+
+=item B<CacheFlush> I<Seconds>
+
+For each host/plugin/type combination the C<network plugin> caches the time of
+the last value being sent or received. Every I<Seconds> seconds the plugin
+searches and removes all entries that are older than I<Seconds> seconds, thus
+freeing the unused memory again. Since this process is somewhat expensive and
+normally doesn't do much, this value should not be too small. The default is
+1800 seconds, but setting this to 86400 seconds (one day) will not do much harm
+either.

+using these settings. If you don't want to dive into the depths of RRDTool, you
+can savely ignore these settings.
+
+=over 4
+
+=item B<DataDir> I<Directory>
+
+Set the directory to store CSV-files under. Per default CSV-files are generated
+beneath the daemon's working directory, i.E<nbsp>e. the B<BaseDir>.
+
+=item B<StepSize> I<Seconds>
+
+Sets the stepsize of newly created RRD-files. Ideally (and per default) this
+setting is identical to the global B<Interval>-option and should not be
+smaller. If unsure, don't set this option.
+
+=item B<HeartBeat> I<Seconds>
+
+Sets the heartbeat of newly created RRD-files. Ideally this setting is bigger
+than the B<Interval>-setting, by default it's twice the B<Interval>-setting. If
+unsure, don't set this option.
+
+=item B<RRARows> I<NumRows>
+
+The C<rrdtool plugin> calculates the number of PDPs per CDP based on the
+B<StepSize>, this setting and a timespan. This plugin creates RRD-files with
+three times five RRAs, i. e. five RRAs with the CFs B<MIN>, B<AVERAGE>, and
+B<MAX>. The five RRAs are optimized for graphs covering one hour, one day, one
+week, one month, and one year.
+
+So for each timespan, it calculates how many PDPs need to be consolidated into
+one CDP by calculating:
+ number of PDPs = timespan / (stepsize * rrarows)
+
+Bottom line is, set this no smaller than the width of you graphs in pixels. The
+default is 1200.
+
+=item B<RRATimespan> I<Seconds>
+
+Adds an RRA-timespan, given in seconds. Use this option mulitple times to have
+more then one RRA. If this option is never used, the built-in default of (3600,
+86400, 604800, 2678400, 31622400) is used.
+
+For more information on how RRA-sizes are calculated see B<RRARows> above.
+
+=item B<XFF> I<Factor>
+
+Set the "XFiles Factor". The default is 0.1. If unsure, don't set this option.
+
+=item B<CacheFlush> I<Seconds>
+
+When the C<rrdtool plugin> uses a cache (by setting B<CacheTimeout>, see below)
+it writes all values for a certain RRD-file if the oldest value is older than
+(or equal to) the number of seconds specified. If some RRD-file is not updated
+anymore for some reason (the computer was shut down, the network is broken,
+etc.) some values may still be in the cache. If B<CacheFlush> is set, then the
+entire cache is searched for entries older than B<CacheTimeout> seconds and
+written to disk every I<Seconds> seconds. Since this is kind of expensive and
+does nothing under normal circumstances, this value should not be too small.
+900 seconds might be a good value, though setting this to 7200 seconds doesn't
+normally do much harm either.
+
+=item B<CacheTimeout> I<Seconds>
+
+If this option is set to a value greater than zero, the C<rrdtool plugin> will
+save values in a cache, as described above. Writing multiple values at once
+reduces IO-operations and thus lessens the load produced by updating the files.
+The tradeoff is that the graphs kind of "drag behind" and that more memory is
+used.
+
+=back
+
=head2 Plugin C<sensors>
+The C<sensors plugin> uses B<lm_sensors> to retrieve sensor-values. This means
+that all the needed modules have to be loaded and lm_sensors has to be
+configured (most likely by editing F</etc/sensors.conf>. Read
+L<sensors.conf(5)> for details.
+
+The B<lm_sensors> homepage can be found at

-=item B<ExtendedSensorNaming> I<true>|I<false>
-
-If set to I<true> this option switches on the extended sensors and RRD-files
-naming. This option exists to preserve backwards compatibility. It is
-recommended that you set this option to I<true>. The default is I<false> to
-maintain compatibility only.
-
-Sensors get names like I<chip-bus-address/type-feature> (e.g.
-I<it8712-isa-0290/voltage-in1>) and RRD files are therefore stored in a
-standalone directory inside the B<DataDir> directory and get names like
-I<lm_sensors-chip-bus-address/type-feature.rrd> (e.g.
-I<lm_sensors-it8712-isa-0290/voltage-in1.rrd>).
-
-The B<ExtendedSensorNaming> option breaks the compatibility with previous
-sensors and RRD files naming and the place where RRDs are stored. If you turn
-it on, the plugin will create new RRD files in a standalone directory inside
-the B<DataDir> directory and without previous history. You can rename ``old''
-RRD-files to preserve already collected statistics, because the file layout
-hasn't changed. If you have two chips of the same type, you need to use
-B<ExtendedSensorNaming> in order to collect information from both chips.
-
-If not set or set to I<false>, the extended naming is not active. Sensors get
-names like I<chip-feature> (e.g. I<it8712-in1>) and RRD files are stored in the
-main B<DataDir> directory and get names like I<sensors-chip-feature.rrd> (e.g.
-I<sensors-it8712-in1.rrd>). You simply continue using the plugin the old way
-and additionally also getting data for newly added sensors in this mode.

-The naming scheme is dependent on the state of the B<ExtendedSensorNaming>

-For example the option "B<Sensor> I<it8712-in1>" will cause the collectd
-to gather data for the voltage sensor I<in1> of the I<it8712> chip in case
-of the B<ExtendedSensorNaming> option is set to I<false>.

+collectd is a daemon that receives system statistics and makes them available
+in a number of ways. The main daemon itself doesn't have any real functionality
+apart from loading, querying and submitting to plugins. For a description of
+available plugins please see L</PLUGINS> below.
=head1 OPTIONS
+Most of collectd's configuration is done using using a configfile. See
+L<collectd.conf(5)> for an in-depth description of all options.
+
=over 4
=item B<-C> I<E<lt>config-fileE<gt>>
change B<collectd>'s behavior. The path may be relative to the current working
directory.
+=item B<-t>
+
+Test the configuration only. The program immediately exits after parsing the
+config file. A return code not equal to zero indicates an error.
+
=item B<-P> I<E<lt>pid-fileE<gt>>
Specify an alternative pid file. This overwrites any settings in the config
=back
-=head1 MODES
-
-collectd can operate in four different operating modes. The modes are described
-below.
-
-The simplest mode is the so called B<local mode>. Data is collected locally and
-written in RRD files that reside in I<DataDir>. This is the default mode when
-collectd is linked against C<librrd>.
-
-The modes B<client mode> and B<server mode> are used to send data over a
-network and receive it again.
-
-In B<client mode> the daemon collects the data locally and sends its results
-to one or more network addresses. No RRD files are written locally in this
-case. If collectd is not linked against C<librrd> this is the default mode.
-
-If started in B<server mode> the daemon will listen on one or more interfaces
-and write the data it receives to RRD files. No data is collected locally.
-
-In the last mode, B<log mode>, data is collected locally and written in
-text files that reside in I<DataDir>.
-
-Please refer to L<collectd.conf(5)> for the configuration options and default
-values.
-
-=head1 SPECIAL PLUGINS

-This module connects to an Apache webserver and expects the output produced by
-B<mod_status.c>. If requires B<libcurl> to set up the HTTP connection and issue
-the request(s). The following is a sample config for the Apache webserver. The
-use of C<ExtendedStatus on> is mandatory.

-This plugin requires further configuration. Please read L<collectd.conf(5)>.
-
-=head2 cpufreq
-
-This module reads F</sys/devices/system/cpu/cpu0/cpufreq/scaling_cur_freq> (for
-the first CPU installed) to get the current CPU frequency. If this file does
-not exist make sure B<cpufreqd> (L<http://cpufreqd.sourceforge.net/>) or a
-similar tool is installed and an "cpu governor" (that's kernel module) is
-loaded.
-
-=head2 email
-
-This plugin collects data indirectly by providing a UNIX socket that external
-programs can connect to. A simple line based protocol is used to communicate
-with the plugin:
-
-E-Mail type (e.g. "ham", "spam", "virus", ...) and size (bytes):
-
- e:<type>:<size>
-
-If C<size> is less than or equal to zero, C<size> is ignored.
-
-Spam score:
-
- s:<value>
-
-Successful spam checks (e.g. "BAYES_99", "SUBJECT_DRUG_GAP_C", ...):
-
- c:<type1>[,<type2>,...]
-
-Each line is limited to 256 characters (including the newline character).
-Longer lines will be ignored.
+=head1 PLUGINS
-=head2 mysql
+As noted above, the real power of collectd lies within it's plugins. A
+(hopefully complete) list of plugins and short descriptions can be found in the
+F<README> file that is distributed with the sourcecode. If you're using a
+package it's a good bet to search somewhere near F</usr/share/doc/collectd>.
-Requires B<mysqlclient> to be installed. It connects to the database when
-started and keeps the connection up as long as possible. When the connection is
-interrupted for whatever reason it will try to re-connect. The syslog will
-contain loud complaints in case anything goes wrong.
-
-This plugin issues C<SHOW STATUS> and evaluates C<Bytes_{received,sent}>,
-C<Com_*> and C<Handler_*> which correspond to F<traffic-mysql.rrd>,
-F<mysql_commands-*.rrd> and F<mysql_handler-*.rrd>. Also, the values of
-C<Qcache_*> are put in F<mysql_qcache.rrd> and values of C<Threads_*> are put
-in F<mysql_threads.rrd>. Please refer to the B<MySQL reference manual>,
-I<5.2.4. Server Status Variables> for an explanation of these values.
-
-=head2 sensors
-
-The B<sensors> module uses lm_sensors to retrieve sensor-values. This means
-that all the needed modules have to be loaded and lm_sensors has to be
-configured (most likely by editing F</etc/sensors.conf>. Read
-L<sensors.conf(5)> for details.
-
-The B<lm_sensors> homepage can be found at
-L<http://secure.netroedge.com/~lm78/>.
-
-=head2 mbmon
-
-The B<mbmon> module uses mbmon to retrieve temperature, voltage, etc.
-
-collectd connects to B<localhost> (127.0.0.1), port B<411/tcp>.
-The B<Host> and B<Port> options can be used to change these
-default values. See L<collectd.conf(5)> for details. C<mbmon> has to be
-running to work correctly. If C<mbmon> is not running timeouts may appear
-which may interfere with other statistics..
-
-C<mbmon> must be run with the -r option ("print TAG and Value format");
-Debian's /etc/init.d/mbmon script already does this, other people
-will need to ensure that this is the case.
-
-=head2 hddtemp
-
-To get values from B<hddtemp> collectd connects to B<localhost> (127.0.0.1),
-port B<7634/tcp>. The B<Host> and B<Port> options can be used to change these
-default values. See L<collectd.conf(5)> for details. C<hddtemp> has to be
-running to work correctly. If C<hddtemp> is not running timeouts may appear
-which may interfere with other statistics..
-
-The B<hddtemp> homepage can be found at
-L<http://www.guzu.net/linux/hddtemp.php>.
-
-=head2 vserver
-
-B<VServer> support is only available for Linux. It cannot yet be found in a
-vanilla kernel, though. To make use of this plugin you need a kernel that has
-B<VServer> support built in, i.e. you need to apply the patches and compile
-your own kernel, which will then provide the /proc/virtual filesystem that is
-required by this plugin.
-
-The B<VServer> homepage can be found at L<http://linux-vserver.org/>.
-
-=head1 RRD FILES
-
-The RRD files are created automatically. The size of the RRAs depend on the
-compile time settings of I<step> and I<width>. With the default values (I<step>
-= B<10>, I<width> = B<1200>) the following RRAs are created:
-
- RRA:AVERAGE:0.1:1:8640
- RRA:AVERAGE:0.1:50:1210
- RRA:AVERAGE:0.1:223:1202
- RRA:AVERAGE:0.1:2635:1201
- RRA:MIN:0.1:1:8640
- RRA:MIN:0.1:50:1210
- RRA:MIN:0.1:223:1202
- RRA:MIN:0.1:2635:1201
- RRA:MAX:0.1:1:8640
- RRA:MAX:0.1:50:1210
- RRA:MAX:0.1:223:1202
- RRA:MAX:0.1:2635:1201
-
-By default collectd uses a 10 second I<step>. Thus the RRAs contain the
-following timespans. If you've changed the I<step> at compile time you will
-have calculate resolution and timespan yourself.
-
- PDP per CDP | Resolution | Data points | Timespan
- ------------+--------------+-------------+---------
- 1 | 10.0 seconds ! 8640 ! 1 day
- 50 | 8.3 minutes | 1210 | 1 week
- 223 | 37.2 minutes | 1202 | 1 month
- 2635 | 7.3 hours | 1201 | 1 year
-
-The DS'es depend on the module creating the RRD files:

+Of course not all plugins fit neatly into one of the two above categories. The
+C<network plugin>, for example, is able to send (i.E<nbsp>e. "write") B<and>
+receive (i.E<nbsp>e. "dispatch") values. Also, it opens a socket upon
+initialization and dispatches the values when it receives them and isn't
+triggered at the same time the input plugins are being read. You can think if
+the network receive part as working asynchronous if it helps.

+In addition to the above, there are "logging plugins". Right now those are the
+C<logfile plugin> and the C<syslog plugin>. With these plugins collectd can
+provide information about issues and significant situations to the user.
+Several loglevels let you suppress uninteresting messages.
-=back
+Please note that some plugins, that provide other means of communicating with
+the daemon, have manpages of their own to describe their functionality in more
+detail. In particular those are L<collectd-email(5)>, L<collectd-exec(5)>,
+L<collectd-perl(5)>, and L<collectd-unixsock(5)>

+ GNU GENERAL PUBLIC LICENSE
+ Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.
+ 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+ Preamble
+
+ The licenses for most software are designed to take away your
+freedom to share and change it. By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users. This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it. (Some other Free Software Foundation software is covered by
+the GNU Library General Public License instead.) You can apply it to
+your programs, too.
+
+ When we speak of free software, we are referring to freedom, not
+price. Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+ To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+ For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have. You must make sure that they, too, receive or can get the
+source code. And you must show them these terms so they know their
+rights.
+
+ We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+ Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software. If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+ Finally, any free program is threatened constantly by software
+patents. We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary. To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+ The precise terms and conditions for copying, distribution and
+modification follow.
+\f
+ GNU GENERAL PUBLIC LICENSE
+ TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+ 0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License. The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language. (Hereinafter, translation is included without limitation in
+the term "modification".) Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope. The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+ 1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+ 2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+ a) You must cause the modified files to carry prominent notices
+ stating that you changed the files and the date of any change.
+
+ b) You must cause any work that you distribute or publish, that in
+ whole or in part contains or is derived from the Program or any
+ part thereof, to be licensed as a whole at no charge to all third
+ parties under the terms of this License.
+
+ c) If the modified program normally reads commands interactively
+ when run, you must cause it, when started running for such
+ interactive use in the most ordinary way, to print or display an
+ announcement including an appropriate copyright notice and a
+ notice that there is no warranty (or else, saying that you provide
+ a warranty) and that users may redistribute the program under
+ these conditions, and telling the user how to view a copy of this
+ License. (Exception: if the Program itself is interactive but
+ does not normally print such an announcement, your work based on
+ the Program is not required to print an announcement.)
+\f
+These requirements apply to the modified work as a whole. If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works. But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+ 3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+ a) Accompany it with the complete corresponding machine-readable
+ source code, which must be distributed under the terms of Sections
+ 1 and 2 above on a medium customarily used for software interchange; or,
+
+ b) Accompany it with a written offer, valid for at least three
+ years, to give any third party, for a charge no more than your
+ cost of physically performing source distribution, a complete
+ machine-readable copy of the corresponding source code, to be
+ distributed under the terms of Sections 1 and 2 above on a medium
+ customarily used for software interchange; or,
+
+ c) Accompany it with the information you received as to the offer
+ to distribute corresponding source code. (This alternative is
+ allowed only for noncommercial distribution and only if you
+ received the program in object code or executable form with such
+ an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it. For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable. However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+\f
+ 4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License. Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+ 5. You are not required to accept this License, since you have not
+signed it. However, nothing else grants you permission to modify or
+distribute the Program or its derivative works. These actions are
+prohibited by law if you do not accept this License. Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+ 6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions. You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+ 7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License. If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all. For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices. Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+\f
+ 8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded. In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+ 9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time. Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number. If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation. If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+ 10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission. For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this. Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+ NO WARRANTY
+
+ 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+ 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+ END OF TERMS AND CONDITIONS
+\f
+ How to Apply These Terms to Your New Programs
+
+ If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+ To do so, attach the following notices to the program. It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+ <one line to give the program's name and a brief idea of what it does.>
+ Copyright (C) <year> <name of author>
+
+ This program is free software; you can redistribute it and/or modify
+ it under the terms of the GNU General Public License as published by
+ the Free Software Foundation; either version 2 of the License, or
+ (at your option) any later version.
+
+ This program is distributed in the hope that it will be useful,
+ but WITHOUT ANY WARRANTY; without even the implied warranty of
+ MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
+ GNU General Public License for more details.
+
+ You should have received a copy of the GNU General Public License
+ along with this program; if not, write to the Free Software
+ Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
+
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+ Gnomovision version 69, Copyright (C) year name of author
+ Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+ This is free software, and you are welcome to redistribute it
+ under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License. Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary. Here is a sample; alter the names:
+
+ Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+ `Gnomovision' (which makes passes at compilers) written by James Hacker.
+
+ <signature of Ty Coon>, 1 April 1989
+ Ty Coon, President of Vice
+
+This General Public License does not permit incorporating your program into
+proprietary programs. If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library. If this is what you want to do, use the GNU Library General
+Public License instead of this License.

+ * write-functions.
*
* ARGUMENTS
- * `host' Host(name) from which the data originates.
- * `type' Name of the plugin.
- * `inst' Instance (passed to the plugin's `write' function.
- * `val' Values for the RRD files. Also passed to the plugin.

+ * `vl' Value list of the values that have been read by a `read'
