- cpufreq
CPU frequency (For laptops with speed step or a similar technology)
+ - dbi
+ Executes SQL statements on various databases and interprets the returned
+ data.
+
- df
Mountpoint usage (Basically the values `df(1)' delivers)
Iptables' counters: Number of bytes that were matched by a certain
iptables rule.
+ - ipmi
+ IPMI (Intelligent Platform Management Interface) sensors information.
+
- ipvs
IPVS connection statistics (number of connections, octets and packets
for each service and destination).
PostgreSQL database statistics: active server connections, transaction
numbers, block IO, table row manipulations.
+ - powerdns
+ PowerDNS name server statistics.
+
- processes
Process counts: Number of running, sleeping, zombie, ... processes.
+ - rrdcached
+ RRDtool caching daemon (RRDcacheD) statistics.
+
- sensors
System sensors, accessed using lm_sensors: Voltages, temperatures and
fan rotation speeds.
- tcpconns
Number of TCP connections to specific local and remote ports.
+ - teamspeak2
+ TeamSpeak2 server statistics.
+
+ - thermal
+ Linux ACPI thermal zone information.
+
- users
Users currently logged in.
you can easily do weird stuff with the plugins we didn't dare think of
;) See collectd-perl(5).
+ - rrdcached
+ Output to round-robin-database (RRD) files using the RRDtool caching
+ daemon (RRDcacheD) - see rrdcached(1). That daemon provides a general
+ implementation of the caching done by the `rrdtool' plugin.
+
- rrdtool
Output to round-robin-database (RRD) files using librrd. See rrdtool(1).
This is likely the most popular destination for such values. Since
needed. Please read collectd-unixsock(5) for a description on how that's
done.
+ * Filtering and rewriting values dispatched to collectd can be done by the
+ following plugins:
+
+ - filter_pcre
+ Filter and rewrite value lists based on Perl-compatible regular
+ expressions.
+
* Logging is, as everything in collectd, provided by plugins. The following
plugins keep up informed about what's going on:
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 maintenance is necessary. Setup is kept as easy
as possible and the default values should be okay for most users.
* CoreFoundation.framework and IOKit.framework (optional)
For compiling on Darwin in general and the `apple_sensors' plugin in
particular.
+ <http://developer.apple.com/corefoundation/>
* libcurl (optional)
If you want to use the `apache', `ascent', or `nginx' plugin.
+ <http://curl.haxx.se/>
+
+ * libdbi (optional)
+ Used by the `dbi' plugin to connect to various databases.
+ <http://libdbi.sourceforge.net/>
* libesmtp (optional)
For the `notify_email' plugin.
+ <http://www.stafford.uklinux.net/libesmtp/>
* libhal (optional)
If present, the uuid plugin will check for UUID from HAL.
+ <http://hal.freedesktop.org/>
- * libiptc (optional)
+ * libiptc (optional, if not found a version shipped with this distribution
+ can be used if the Linux kernel headers are available)
For querying iptables counters.
+ <http://netfilter.org/>
* libmysqlclient (optional)
Unsurprisingly used by the `mysql' plugin.
+ <http://dev.mysql.com/>
* libnetlink (optional)
Used, obviously, for the `netlink' plugin.
+ <http://www.linuxfoundation.org/en/Net:Iproute2>
* libnetsnmp (optional)
For the `snmp' plugin.
+ <http://www.net-snmp.org/>
* libnotify (optional)
For the `notify_desktop' plugin.
+ <http://www.galago-project.org/>
* 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.
+ <http://verplant.org/liboping/>
* libowcapi (optional)
Used by the `onewire' plugin to read values from onewire sensors (or the
owserver(1) daemon).
+ <http://www.owfs.org/>
* libpcap (optional)
Used to capture packets by the `dns' plugin.
+ <http://www.tcpdump.org/>
+
+ * libpcre (optional)
+ Used by the `filter_pcre' plugin.
+ <http://www.pcre.org/>
* libperl (optional)
Obviously used by the `perl' plugin. The library has to be compiled with
ithread support (introduced in Perl 5.6.0).
+ <http://www.perl.org/>
* libpq (optional)
The PostgreSQL C client library used by the `postgresql' plugin.
+ <http://www.postgresql.org/>
- * 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 its values via multicast and not create any RRD files itself.
- Alternatively you can chose to write CSV-files (Comma Separated Values)
- instead.
+ * librrd (optional)
+ Used by the `rrdtool' and `rrdcached' plugins. The latter requires RRDtool
+ client support which was added after version 1.3 of RRDtool. Versions 1.0,
+ 1.2 and 1.3 are known to work with the `rrdtool' plugin.
+ <http://oss.oetiker.ch/rrdtool/>
* librt, libsocket, libkstat, libdevinfo (optional)
Various standard Solaris libraries which provide system functions.
+ <http://developers.sun.com/solaris/>
* libsensors (optional)
To read from `lm_sensors', see the `sensors' plugin.
+ <http://www.lm-sensors.org/>
- * libstatgrab (optional) 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/>
+ * libstatgrab (optional)
+ Used by various plugins to collect statistics on systems other than Linux
+ and/or Solaris.
+ <http://www.i-scream.org/libstatgrab/>

+ <http://libvirt.org/>
* libxml2 (optional)
Parse XML data. This is needed for the `ascent' and `libvirt' plugins.
+ <http://xmlsoft.org/>
* libxmms (optional)
+ <http://www.xmms.org/>
Configuring / Compiling / Installing
`./configure && make && make install'. For detailed, generic instructions
see INSTALL. For a complete list of configure options and their description,
run `./configure --help'.
-
+
By default, the configure script will check for all build dependencies and
disable all plugins whose requirements cannot be fulfilled (any other plugin
will be enabled). To enable a plugin, install missing dependencies (see
-* Parse options/identifiers with spaces in them correctly.
-* Figure out what to do with the onewire plugin.
+* Finalize the onewire plugin.
* Custom notification messages?
+* Implement moving-average calculation for the threshold stuff.
src/battery.c: commend not working code.
- be free of syntax errors.
* Port nfs module to solaris
* Port tape module to Linux
+* Port the apple_sensors plugin to Linux/PPC.
* Maybe look into porting the serial module
* Build Darwin package
* Maybe let the network plugin configure whether or not notifications should be

+-- Description
+--------------
+-- This will create a schema to provide collectd with the required permissions
+-- and space for statistic data.
+-- The idea is to store the output of some expensive queries in static tables
+-- and fill these tables with dbms_scheduler jobs as often as necessary.
+-- collectd will then just read from the static tables. This will reduces the
+-- chance that your system will be killed by excessive monitoring queries and
+-- gives the dba control on the interval the information provided to collectd
+-- will be refreshed. You have to create a dbms_scheduler job for each of the
+-- schemas you what to monitor for object-space-usage. See the example below.
+--
+-- Requirements
+---------------
+-- make sure you have:
+-- write permission in $PWD
+-- you have GID of oracle software owner
+-- set $ORACLE_HOME
+-- set $ORACLE_SID
+-- DB is up an running in RW mode
+-- execute like this:
+-- sqlplus /nolog @ create_collectd-schema.dll
+
+spool create_collectd-schema.log
+connect / as sysdba
+
+-- Create user, tablespace and permissions

+=head2 Plugin C<dbi>
+
+This plugin uses the "B<dbi>" library (L<http://libdbi.sourceforge.net/>) to
+connect to various databases, execute SQL statements and read back the results.
+You can configure how each column is to be interpreted and the plugin will
+generate one data set from each row returned according to these rules.
+
+Because the plugin is very generic, the configuration is a little more complex
+than those of other plugins. It usually looks something like this:
+
+ <Plugin dbi>
+ <Query "out_of_stock">
+ Statement "SELECT category, COUNT(*) AS value FROM products WHERE in_stock = 0 GROUP BY category"
+ Type "gauge"
+ InstancesFrom "category"
+ ValuesFrom "value"
+ </Query>
+ <Database "product_information">
+ Driver "mysql"
+ DriverOption "host" "localhost"
+ DriverOption "username" "collectd"
+ DriverOption "password" "aZo6daiw"
+ DriverOption "dbname" "prod_info"
+ SelectDB "prod_info"
+ Query "out_of_stock"
+ </Database>
+ </Plugin>
+
+The configuration above defines one query and one database. The query is then
+linked to the database with the B<Query> option I<within> the
+B<E<lt>DatabaseE<gt>> block. You can have any number of queries and databases
+and you can also use the B<Include> statement to split up the configuration
+file in multiple, smaller files. However, the B<E<lt>QueryE<gt>> block I<must>
+precede the B<E<lt>DatabaseE<gt>> blocks, because the file is interpreted from
+top to bottom!
+
+The following is a complete list of options:
+
+=head3 B<Query> blocks
+
+Query blocks define SQL statements and how the returned data should be
+interpreted. They are identified by the name that is given in the opening line
+of the block. Thus the name needs to be unique. Other than that, the name is
+not used in collectd.
+
+=over 4
+
+=item B<Statement> I<SQL>
+
+Sets the statement that should be executed on the server. This is B<not>
+interpreted by collectd, but simply passed to the database server. Therefore,
+the SQL dialect that's used depends on the server collectd is connected to.
+
+The query has to return at least two columns, one for the instance and one
+value. You cannot omit the instance, even if the statement is guaranteed to
+always return exactly one line. In that case, you can usually specify something
+like this:
+
+ Statement "SELECT \"instance\", COUNT(*) AS value FROM table"
+
+(That works with MySQL but may not be valid SQL according to the spec. If you
+use a more strict database server, you may have to select from a dummy table or
+something.)
+
+=item B<Type> I<Type>
+
+The B<type> that's used for each line returned. See L<types.db(5)> for more
+details on how types are defined. In short: A type is a predefined layout of
+data and the number of values and type of values has to match the type
+definition.
+
+If you specify "temperature" here, you need exactly one gauge column. If you
+specify "if_octets", you will need two counter columns. See the B<ValuesFrom>
+setting below.
+
+=item B<InstancesFrom> I<column0> [I<column1> ...]
+
+Specifies the columns whose values will be used to create the "TypeInstance"
+for each row. You need to specify at least one column for each query. If you
+specify more than one column, the value of all columns will be join together
+with the hyphen as separation character.
+
+The plugin itself does not check whether or not all built instances are
+different. It's your responsibility to assure that each is unique.
+
+=item B<ValuesFrom> I<column0> [I<column1> ...]
+
+Names the columns whose content is used as the actual data for the data sets
+that are dispatched to the daemon. How many such columns you need is determined
+by the B<Type> setting above. If you specify too many or not enough columns,
+the plugin will complain about that and no data will be submitted to the
+daemon.
+
+The actual data type in the columns is not that important. The plugin will
+automatically cast the values to the right type if it know how to do that. So
+it should be able to handle integer an floating point types, as well as strings
+(if they include a number at the beginning).
+
+=back
+
+=head3 B<Database> blocks
+
+Database blocks define a connection to a database and which queries should be
+sent to that database. Since the used "dbi" library can handle a wide variety
+of databases, the configuration is very generic. If in doubt, refer to libdbi's
+documentationE<nbsp>- we stick as close to the terminology used there.
+
+Each database needs a "name" as string argument in the starting tag of the
+block. This name will be used as "PluginInstance" in the values submitted to
+the daemon. Other than that, that name is not used.
+
+=over 4
+
+=item B<Driver> I<Driver>
+
+Specifies the driver to use to connect to the database. In many cases those
+drivers are named after the database they can connect to, but this is not a
+technical necessity. These drivers are sometimes referred to as "DBD",
+B<D>ataB<B>ase B<D>river, and some distributions ship them in separate
+packages. Drivers for the "dbi" library are developed by the B<libdbi-drivers>
+project at L<http://libdbi-drivers.sourceforge.net/>.
+
+You need to give the driver name as expected by the "dbi" library here. You
+should be able to find that in the documentation for each driver. If you
+mistype the driver name, the plugin will dump a list of all known driver names
+to the log.
+
+=item B<DriverOption> I<Key> I<Value>
+
+Sets driver-specific options. What option a driver supports can be found in the
+documentation for each driver, somewhere at
+L<http://libdbi-drivers.sourceforge.net/>. However, the options "host",
+"username", "password", and "dbname" seem to be deE<nbsp>facto standards.
+
+Unfortunately, drivers are not too keen to report errors when an unknown option
+is passed to them, so invalid settings here may go unnoticed. This is not the
+plugin's fault, it will report errors if it gets them from the libraryE<nbsp>/
+the driver. If a driver complains about an option, the plugin will dump a
+complete list of all options understood by that driver to the log.
+
+=item B<SelectDB> I<Database>
+
+In some cases, the database name you connect with is not the database name you
+want to use for querying data. If this option is set, the plugin will "select"
+(switch to) that database after the connection is established.
+
+=item B<Query> I<QueryName>
+
+Associates the query named I<QueryName> with this database connection. The
+query needs to be defined I<before> this statement, i.E<nbsp>e. all query
+blocks you want to refer to must be placed above the database block you want to
+refer to them from.

+=head2 Plugin C<filter_pcre>
+
+This plugin allows you to filter and rewrite value lists based on
+Perl-compatible regular expressions whose syntax and semantics are as close as
+possible to those of the Perl 5 language. See L<pcre(3)> for details.
+
+ <Plugin filter_pcre>
+ <RegEx>
+ Host "^mail\d+$"
+ Plugin "^tcpconns$"

+ </RegEx>
+
+ <RegEx>
+ Plugin "^sensors$"
+ PluginInstance "^Some Weird Sensor Chip Name Prefix"
+
+ SubstitutePluginInstance "foo"
+ </RegEx>
+ </Plugin>
+
+The configuration consists of one or more C<RegEx> blocks, each of which
+specifies a regular expression identifying a set of value lists and how to
+handle successful matches. A value list keeps the values of a single data-set
+and is identified by the tuple (host, plugin, plugin instance, type, type
+instance). The plugin and type instances are optional components. If they are
+missing they are treated as empty strings. Within those blocks, the following
+options are recognized:
+
+=over 4

+
+=item B<Plugin> I<regex>
+
+=item B<PluginInstance> I<regex>
+
+=item B<Type> I<regex>
+
+=item B<TypeInstance> I<regex>
+
+Specifies the regular expression for each component of the identifier. If any
+of these options is missing it is interpreted as a pattern which matches any
+string. All five components of a value list have to match the appropriate
+regular expression to trigger the specified action.
+
+=item B<Action> I<NoWrite>|I<NoThresholdCheck>|I<Ignore>
+
+Specify how to handle successful matches:
+
+=over 4
+
+=item B<NoWrite>
+
+Do not send the value list to any output (a.k.a. write) plugins.
+
+=item B<NoThresholdCheck>
+
+Skip threshold checking for this value list.
+
+=item B<Ignore>
+
+Completely ignore this value list.
+
+=back
+
+Two or more actions may be combined by specifying multiple B<Action> options.
+
+=item B<SubstituteHost> I<replacement>
+
+=item B<SubstitutePlugin> I<replacement>
+
+=item B<SubstitutePluginInstance> I<replacement>
+
+=item B<SubstituteType> I<replacement>
+
+=item B<SubstituteTypeInstance> I<replacement>
+
+Upon a successful match, the matching substring will be replaced by the
+specified I<replacement> text. These options require that an appropriate regex
+has been specified before, e.E<nbsp>g. B<SubstituteHost> requires that the
+B<Host> option has been specified before.
+
+B<Note>: It is not recommended to modify the type unless you really know what
+you are doing. The type is used to identify the data-set definition of the
+dispatched values.

Select this database. Defaults to I<no database> which is a perfectly reasonable
option for what this plugin does.

+=head2 Plugin C<oracle>
+
+The "oracle" plugin uses the Oracle® Call Interface (OCI) to connect to an
+Oracle® Database and lets you execute SQL statements there. It is very similar
+to the "dbi" plugin, because it was written around the same time. See the "dbi"
+plugin's documentation above for details.
+
+ <Plugin oracle>
+ <Query "out_of_stock">
+ Statement "SELECT category, COUNT(*) AS value FROM products WHERE in_stock = 0 GROUP BY category"
+ Type "gauge"
+ InstancesFrom "category"
+ ValuesFrom "value"
+ </Query>
+ <Database "product_information">
+ ConnectID "db01"
+ Username "oracle"
+ Password "secret"
+ Query "out_of_stock"
+ </Database>
+ </Plugin>
+
+=head3 B<Query> blocks
+
+The Query blocks are handled identically to the Query blocks of the "dbi"
+plugin. Please see its documentation above for details on how to specify
+queries.
+
+=head3 B<Database> blocks
+
+Database blocks define a connection to a database and which queries should be
+sent to that database. Each database needs a "name" as string argument in the
+starting tag of the block. This name will be used as "PluginInstance" in the
+values submitted to the daemon. Other than that, that name is not used.
+
+=over 4
+
+=item B<ConnectID> I<ID>
+
+Defines the "database alias" or "service name" to connect to. Usually, these
+names are defined in the file named C<$ORACLE_HOME/network/admin/tnsnames.ora>.
+
+=item B<Username> I<Username>
+
+Username used for authentication.
+
+=item B<Password> I<Password>
+
+Password used for authentication.
+
+=item B<Query> I<QueryName>
+
+Associates the query named I<QueryName> with this database connection. The
+query needs to be defined I<before> this statement, i.E<nbsp>e. all query
+blocks you want to refer to must be placed above the database block you want to
+refer to them from.

=head2 Plugin C<perl>
This plugin embeds a Perl-interpreter into collectd and provides an interface
(RSS), user- and system-time used, number of processes and number of threads,
and minor and major pagefaults.
+=item B<ProcessMatch> I<name> I<regex>
+
+Similar to the B<Process> option this allows to select more detailed
+statistics of processes matching the specified I<regex> (see L<regex(7)> for
+details). The statistics of all matching processes are summed up and
+dispatched to the daemon using the specified I<name> as an identifier. This
+allows to "group" several processes together. I<name> must not contain
+slashes.
+
+=back
+
+=head2 Plugin C<rrdcached>
+
+The C<rrdcached> plugin uses the RRDTool accelerator daemon, L<rrdcached(1)>,
+to store values to RRD files in an efficient manner. The combination of the
+C<rrdcached> B<plugin> and the C<rrdcached> B<daemon> is very similar to the
+way the C<rrdtool> plugin works (see below). The added abstraction layer
+provides a number of benefits, though: Because the cache is not within
+C<collectd> anymore, it does not need to be flushed when C<collectd> is to be
+restarted. This results in much shorter (if any) gaps in graphs, especially
+under heavy load. Also, the C<rrdtool> command line utility is aware of the
+daemon so that it can flush values to disk automatically when needed. This
+allows to integrate automated flushing of values into graphing solutions much
+more easily.
+
+There are disadvantages, though: The daemon may reside on a different host, so
+it may not be possible for C<collectd> to create the appropriate RRD files
+anymore. And even if C<rrdcached> runs on the same host, it may run in a
+different base directory, so relative paths may do weird stuff if you're not
+careful.
+
+So the B<recommended configuration> is to let C<collectd> and C<rrdcached> run
+on the same host, communicating via a UNIX domain socket. The B<DataDir>
+setting should be set to an absolute path, so that a changed base directory
+does not result in RRD files being createdE<nbsp>/ expected in the wrong place.
+
+=over 4
+
+=item B<DaemonAddress> I<Address>
+
+Address of the daemon as understood by the C<rrdc_connect> function of the RRD
+library. See L<rrdcached(1)> for details. Example:
+
+ <Plugin "rrdcached">
+ DaemonAddress "unix:/var/run/rrdcached.sock"
+ </Plugin>
+
+=item B<DataDir> I<Directory>
+
+Set the base directory in which the RRD files reside. If this is a relative
+path, it is relative to the working base directory of the C<rrdcached> daemon!
+Use of an absolute path is recommended.
+
+=item B<CreateFiles> B<true>|B<false>
+
+Enables or disables the creation of RRD files. If the daemon is not running
+locally, or B<DataDir> is set to a relative path, this will not work as
+expected. Default is B<true>.

+=head1 FILTER CONFIGURATION
+
+TODO: Update this entire section once development is done.
+
+Starting with collectd 4.6 there is a powerful filtering infrastructure
+implemented in the daemon. The concept has mostly been copied from I<iptables>,
+the packet filter infrastructure for Linux. We'll use a similar terminology, so
+that users that are familiar with iptables feel right at home.
+
+=head2 Terminology
+
+The most important terms are:
+
+=over 4
+
+=item B<Match>
+
+A I<match> is a criteria to select specific values. Examples are, of course, the
+name of the value or it's current value.
+
+=item B<Target>
+
+A I<target> is some action that is to be performed with data. Such actions
+could, for example, be to change part of the value's identifier or to ignore
+the value completely. Built-in functions are B<write> and B<stop>, see below.
+
+Some targets, for example the built-in B<stop> target, signal that processing
+of a value should be stopped. In that case processing of the current chain will
+be aborted.
+
+=item B<Rule>
+
+The combination of any number of matches and at least one target is called a
+I<rule>. The target actions will be performed for all values for which B<all>
+matches apply. If the rule does not have any matches associated with it, the
+target action will be performed for all values.
+
+If any target returns the stop condition, the processing will stop right away.
+This means that any targets following the current one will not be called after
+the stop condition has been returned.
+
+=item B<Chain>
+
+A I<chain> is a list of rules and possibly default targets. The rules are tried
+in order and if one matches, the associated target will be called. If a value
+is handled by a rule, it depends on the target whether or not any subsequent
+rules are considered or if traversal of the chain is aborted. After all rules
+have been checked and no target returned the stop condition, the default
+targets will be executed.
+
+=back
+
+=head2 General structure
+
+The following shows the resulting structure:
+
+ +---------+
+ ! Chain !
+ +---------+
+ !
+ V
+ +---------+ +---------+ +---------+ +---------+
+ ! Rule !->! Match !->! Match !->! Target !

+ ! Default !
+ ! Target !
+ +---------+
+
+=head2 Synopsis
+
+The configuration reflects this structure directly:
+
+ <Chain "main">
+ <Rule "ignore_mysql_show">
+ <Match "regex">
+ Plugin "^mysql$"
+ Type "^mysql_command$"
+ TypeInstance "^show_"
+ </Match>
+ <Target "stop">
+ </Target>
+ </Rule>
+ <Target "write">
+ Plugin "rrdtool"
+ </Target>
+ </Chain>
+
+The above configuration example will ignore all values where the plugin field
+is "mysql", the type is "mysql_command" and the type instance begins with
+"show_". All other values will be sent to the "rrdtool" write plugin via the
+default target of the chain.
+
+=head2 List of configuration options
+
+=over 4
+
+=item B<Chain> I<Name>
+
+Adds a new chain with a certain name. This name can be used to refer to a
+specific chain, for example to jump to it.
+
+Within the B<Chain> block, there can be B<Rule> blocks and B<Target> blocks.
+
+=item B<Rule> [I<Name>]
+
+Adds a new rule to the current chain. The name of the rule is optional and
+currently has no meaning for the daemon.
+
+Within the B<Rule> block, there may be any number of B<Match> blocks and there
+must be at least one B<Target> block.
+
+=item B<Match> I<Name>
+
+Adds a match to a B<Rule> block. The name specifies what kind of match should
+be performed. Available matches depend on the plugins that have been loaded.
+
+The arguments inside the B<Match> block are passed to the plugin implementing
+the match, so which arguments are valid here depends on the plugin being used.
+If you do not need any to pass any arguments to a match, you can use the
+shorter syntax:
+
+ Match "foobar"
+
+Which is equivalent to:
+
+ <Match "foobar">
+ </Match>
+
+=item B<Target> I<Name>
+
+Add a target to a rule or a default target to a chain. The name specifies what
+kind of target is to be added. Which targets are available depends on the
+plugins being loaded.
+
+The arguments inside the B<Target> block are passed to the plugin implementing
+the target, so which arguments are valid here depends on the plugin being used.
+If you do not need any to pass any arguments to a target, you can use the
+shorter syntax:

+ Target "stop"
+
+This is the same as writing:
+
+ <Target "stop">

+
+=head2 Built-in targets
+
+The following targets are built into the core daemon and therefore need no
+plugins to be loaded:
+
+=over 4
+
+=item B<return>
+
+Signals the "return" condition. This causes the current chain to stop
+processing the value and returns control to the calling chain. The calling
+chain will continue processing targets and rules just after the B<jump> target
+(see below). This is very similar to the B<RETURN> target of iptables, see
+L<iptables(8)>.
+
+This target does not have any options.
+
+Example:
+
+ Target "return"
+
+=item B<stop>
+
+Signals the "stop" condition, causing processing of the value to be aborted
+immediately. This is similar to the B<DROP> target of iptables, see
+L<iptables(8)>.
+
+This target does not have any options.
+
+Example:
+
+ Target "stop"
+
+=item B<write>
+
+Sends the value to write plugins.
+
+Available options:
+
+=over 4
+
+=item B<Plugin> I<Name>
+
+Name of the write plugin to which the data should be sent. This option may be
+given multiple times to send the data to more than one write plugin.
+

+
+If no plugin is explicitly specified, the values will be sent to all available
+write plugins.
+
+Example:
+
+ <Target "write">
+ Plugin "rrdtool"
+ </Target>
+
+=item B<jump>
+
+Starts processing the rules of another chain. If the end of that chain is
+reached, or a stop condition is encountered, processing will continue right
+after the B<jump> target, i.E<nbsp>e. with the next target or the next rule.
+This is similar to the B<-j> command line option of iptables, see
+L<iptables(8)>.

+
+Example:

+=item B<value>
+
+Matches the actual value of data sources against given minimumE<nbsp>/ maximum

+must match the specified ranges for a positive match.
+
+Available options:
+

+=item B<Min> I<Value>
+
+Sets the smallest value which still results in a match. If unset, behaves like
+negative infinity.

+Sets the largest value which still results in a match. If unset, behaves like
+positive infinity.
+
+=item B<Invert> B<true>|B<false>
+
+Inverts the selection. If the B<Min> and B<Max> settings result in a match,
+no-match is returned and vice versa.

+=head2 Backwards compatibility
+
+If you use collectd with an old configuration, i.E<nbsp>e. one without a
+B<Chain> block, it will behave as it used to. This is equivalent to the
+following configuration:
+
+ <Chain "main">
+ Target "write"
+ </Chain>
+
+If you specify a B<Chain> block anywhere, the B<write> target will not be added
+anywhere and you will have to make sure that it is called where appropriate. We
+suggest to add the above snippet as default target to your main chain.
+
+TODO: Notifications will be implemented using chains, too. Describe that here!
+
+=head2 Examples
+
+Ignore all values, where the hostname does not contain a dot, i.E<nbsp>e. can't
+be an FQDN.

+=======================================

+http://collectd.org/
+
+About
+-----
+
+ This is libiptc taken from the iptables source distribution. As it is not
+ meant to be a public interface by upstream it is not shipped in some binary
+ distributions. Thus, collectd ships its own copy as a fall-back.
+
+ The presently available version was imported from iptables 1.4.1.1.
+
+Changes to the iptables upstream sources:
+-----------------------------------------
+
+ * Added copyright headers mentioning the "Netfilter Core Team" as copyright
+ holder.
+
+ * Changed "libiptc/*" includes to "*".
+
+ * Use the shipped copy of "xtables.h" instead of the one possibly available
+ on the system.

+ * NAME

+ *
+ * DESCRIPTION
+ * Calls the write function of the given plugin with the provided data set and
+ * value list. It differs from `plugin_dispatch_value' in that it does not
+ * update the cache, does no do threshold checking, call the chain subsystem
+ * and so on. It looks up the requested plugin and invokes the function, end
+ * of story.
+ *
+ * ARGUMENTS
+ * plugin Name of the plugin. If NULL, the value is sent to all registered
+ * write functions.
+ * ds Pointer to the data_set_t structure. If NULL, the data set is
+ * looked up according to the `type' member in the `vl' argument.
+ * vl The actual value to be processes. Must not be NULL.
+ *
+ * RETURN VALUE
+ * Returns zero upon success or non-zero if an error occurred. If `plugin' is
+ * NULL and more than one plugin is called, an error is only returned if *all*
+ * plugins fail.
+ *
+ * NOTES
+ * This is the function used by the `write' built-in target. May be used by
+ * other target plugins.

+ * subst:
+ *
+ * Replace a substring of a string with the specified replacement text. The
+ * resulting string is stored in the buffer pointed to by 'buf' of length
+ * 'buflen'. Upon success, the buffer will always be null-terminated. The
+ * result may be truncated if the buffer is too small.
+ *
+ * The substring to be replaces is identified by the two offsets 'off1' and
+ * 'off2' where 'off1' specifies the offset to the beginning of the substring
+ * and 'off2' specifies the offset to the first byte after the substring.
+ *
+ * The minimum buffer size to store the complete return value (including the
+ * terminating '\0' character) thus has to be:
+ * off1 + strlen(replacement) + strlen(string) - off2 + 1
+ *
+ * Example:
+ *
+ * 01234567890
+ * string = "foo_____bar"
+ * ^ ^
+ * | |
+ * off1 off2
+ *
+ * off1 = 3
+ * off2 = 8
+ *
+ * replacement = " - "
+ *
+ * -> "foo - bar"
+ *
+ * The function returns 'buf' on success, NULL else.
