+ * collectd-nagios: The "-m" option has been implemented (treat NaNs as
+ critical).
+ * collectd-tg: Traffic generator creating bogus network traffic
+ compatible to the Network plugin. This utility can be used to
+ stress-test new write plugins and collectd in general.
+ * libcollectdclient: Creating and sending network packets has been
+ added to the collectd client library.
+ * All data sets: The data source name of all data sets with exactly
+ one data source has been changed to "value".
+ * All plugins: All "counter" data sources have been converted to
+ "derive" data sources. All plugins now use "derive" by default, but
+ plugins such as the network plugin can still handle "counter", of
+ course. The minimum value of all derive data sources is zero, the
+ maximum value is unspecified.
+ * amqp plugin: The new AMQP plugin can send data to and receive data
+ from an AMQP broker. Thanks to Sebastien Pahl for his code.
+ * apache plugin: Backwards compatibility code has been removed.
+ Support for the IBM HTTP Server has been added. Thanks to Manuel
+ Luis Sanmartín Rozada for his patch.
+ * contextswitch plugin: Support for sysctlbyname(3) has been added.
+ Thanks to Kimo Rosenbaum for his patch.
+ * df plugin: The default behavior has been changed to be equivalent to
+ the "ReportReserved" behavior of v4.
+ * dns plugin: Improved RFC 1035 name parsing has been imported from
+ "dnstop".
+ * exec plugin: Backwards compatibility code has been removed.
+ * GenericJMX plugin: The "InstancePrefix" option has been added to
+ "Connection" blocks.
+ * hddtemp plugin: The "TranslateDevicename" config option has been
+ removed.
+ * interface plugin: Use the "plugin instance" to store the interface
+ value.
+ * libvirt plugin: The "InterfaceFormat" option has been added. Thanks
+ to Ruben Kerkhof for his patch.
+ * lpar plugin: New plugins for "logical partitions", a virtualization
+ technique of POWER CPUs. Thanks to Aurélien Reynaud for his code and
+ patience.
+ * modbus plugin: Support for libmodbus 2.9.2 has been added and the
+ license has been changed to LGPLv2.1.
+ * mysql plugin: Backwards compatibility code has been removed. The
+ data sets used have been improved.
+ * network plugin: The default buffer size has been increased to
+ 1452 bytes.
+ * perl plugin: Backwards compatibility code has been removed.
+ * postgresql plugin: Backwards compatibility code has been removed.
+ * redis plugin: Plugin for collecting statistics from Redis, a key-
+ value store, has been added. Thanks to Andres J. Diaz for his code.
+ * swap plugin: Implement collection of physical and virtual memory
+ statistics under Solaris. The new default is collecting physical
+ memory. Thanks to Aurélien Reynaud for his patches.
+ * threshold plugin: The threshold configuration has been moved into
+ this separate plugin.
+ * unixsock plugin: The "DeleteSocket" option has been added.
+ * varnish plugin: The new Varnish plugin reads statistics from
+ Varnish, a web accelerator. Thanks to Jérôme Renard and Marc
+ Fournier for their contributions.
+ * write_redis: New plugin for writing data to Redis, a key-value
+ store.
+ * zfs_arc plugin: The data sets have been replaced by more elegant
+ alternatives.
+ * v5upgrade target: Target for converting v4 data sets to the v5
+ schema.
+
2013-04-07, Version 4.10.9
* Build system: A bad interaction between the Java detection code and
libltdl has been fixed. Thanks to Dave Cottlehuber for his patch.

+-- Description:
+-- ------------
+--
+-- This is a sample database setup that may be used to write data collected by
+-- collectd to a PostgreSQL database. We're using two tables, 'identifiers'
+-- and 'values' to store the value-list identifier and the actual values
+-- respectively.
+--
+-- The 'values' table is partitioned to improve performance and maintainance.
+-- Please note that additional maintainance scripts are required in order to
+-- keep the setup running -- see the comments below for details.
+--
+-- The function 'collectd_insert' may be used to actually insert values
+-- submitted by collectd into those tables.
+--
+-- Sample configuration:
+-- ---------------------
+--
+-- <Plugin postgresql>
+-- <Writer sqlstore>
+-- Statement "SELECT collectd_insert($1, $2, $3, $4, $5, $6, $7, $8, $9);"
+-- </Writer>
+-- <Database foo>
+-- # ...
+-- Writer sqlstore
+-- </Database>
+-- </Plugin>

-Summary: Statistics collection daemon for filling RRD files.
+#
+# q: What is this ?
+# a: A specfile for building RPM packages of current collectd releases, for
+# RHEL/CentOS versions 5, 6 and 7. By default all the plugins which are
+# buildable based on the libraries available in the distribution + the
+# EPEL repository, will be built. Plugins depending on external libs will
+# be packaged in separate RPMs.
+#
+# q: And how can I do that ?
+# a: By following these instructions, using mock:
+#
+# - install and configure mock (https://fedoraproject.org/wiki/Projects/Mock)
+#
+# - enable the EPEL repository (http://dl.fedoraproject.org/pub/epel/) in the
+# configuration files for your target systems (/etc/mock/*.cfg).
+#
+# - copy this file in your ~/rpmbuild/SPECS/ directory
+#
+# - fetch the desired collectd release file from https://collectd.org/files/
+# and save it in your ~/rpmbuild/SOURCES/ directory
+#
+# - build the SRPM first:
+# mock -r centos-6-x86_64 --buildsrpm --spec ~/rpmbuild/SPECS/collectd.spec \
+# --sources ~/rpmbuild/SOURCES/
+#
+# - then build the RPMs:
+# mock -r centos-6-x86_64 --no-clean --rebuild \
+# /var/lib/mock/centos-6-x86_64/result/collectd-X.Y.Z-NN.src.rpm
+#
+# - you can also optionally enable/disable plugins which are disabled/enabled
+# by default:
+# mock -r centos-6-x86_64 --no-clean --without=java --with=oracle --rebuild \
+# /var/lib/mock/centos-6-x86_64/result/collectd-X.Y.Z-NN.src.rpm

+# http://collectd.org/
+# Upstart is the replacement init system used in Debian, Ubuntu,
+# and in Fedora. Refer to http://upstart.ubuntu.com/cookbook/
+#
+# Normally this file will live as `/etc/init/collectd.conf`
+
+usage "initctl <start|stop> collectd"
+author "Dave Cottlehuber <dch@jsonified.com>"
+version "1.1"
+
+# There are a number of alternative start sequences however
+# most of those do not work on all Ubuntu flavours and releases.
+start on started networking and filesystem
+stop on runlevel [!2345]
+
+# collectd itself will run with reduced privileges, but not
+# all plugins will. Test and edit as required.
+# An alternative configuration is as a user script in ~/.init/ however
+# these cannot be started at boot time by the system without
+# arcane trickery. Also a root user will not see these tasks/jobs
+# by default. set*id is a reasonable and secure compromise.
+#setuid nobody
+#setgid nobody
+
+# Other parameters such as the path to the configuration file
+# will have been compiled into the binary. These are trivially
+# added as environment variables below, and then into both
+# `pre-start` command check before collectd runs, and subsequent
+# `exec` command parameters below. Remember that upstart runs all
+# shell commands via `sh -e`.
+env DAEMON=/usr/sbin/collectd
+
+# Tell upstart to watch for forking when tracking the pid for us.
+expect fork

This variable keeps the interval in seconds in which the read functions are
queried (see the B<Interval> configuration option).

+=head1 NAME
+
+collectd-threshold - Documentation of collectd's I<Threshold plugin>
+
+=head1 SYNOPSIS
+
+ LoadPlugin "threshold"
+ <Plugin "threshold">
+ <Type "foo">
+ WarningMin 0.00
+ WarningMax 1000.00
+ FailureMin 0.00
+ FailureMax 1200.00
+ Invert false
+ Instance "bar"
+ </Type>
+ </Plugin>
+
+=head1 DESCRIPTION
+
+Starting with version C<4.3.0> I<collectd> has support for B<monitoring>. By
+that we mean that the values are not only stored or sent somewhere, but that
+they are judged and, if a problem is recognized, acted upon. The only action
+the I<Threshold plugin> takes itself is to generate and dispatch a
+I<notification>. Other plugins can register to receive notifications and
+perform appropriate further actions.
+
+Since systems and what you expect them to do differ a lot, you can configure
+I<thresholds> for your values freely. This gives you a lot of flexibility but
+also a lot of responsibility.
+
+Every time a value is out of range, a notification is dispatched. This means
+that the idle percentage of your CPU needs to be less then the configured
+threshold only once for a notification to be generated. There's no such thing
+as a moving average or similar - at least not now.
+
+Also, all values that match a threshold are considered to be relevant or
+"interesting". As a consequence collectd will issue a notification if they are
+not received for B<Timeout> iterations. The B<Timeout> configuration option is
+explained in section L<collectd.conf(5)/"GLOBAL OPTIONS">. If, for example,
+B<Timeout> is set to "2" (the default) and some hosts sends it's CPU statistics
+to the server every 60 seconds, a notification will be dispatched after about
+120 seconds. It may take a little longer because the timeout is checked only
+once each B<Interval> on the server.
+
+When a value comes within range again or is received after it was missing, an
+"OKAY-notification" is dispatched.
+
+=head1 CONFIGURATION
+
+Here is a configuration example to get you started. Read below for more
+information.
+
+ LoadPlugin "threshold"
+ <Plugin "threshold">
+ <Type "foo">
+ WarningMin 0.00
+ WarningMax 1000.00
+ FailureMin 0.00
+ FailureMax 1200.00
+ Invert false
+ Instance "bar"
+ </Type>
+
+ <Plugin "interface">
+ Instance "eth0"
+ <Type "if_octets">
+ FailureMax 10000000
+ DataSource "rx"
+ </Type>
+ </Plugin>
+
+ <Host "hostname">
+ <Type "cpu">
+ Instance "idle"
+ FailureMin 10
+ </Type>
+
+ <Plugin "memory">
+ <Type "memory">
+ Instance "cached"
+ WarningMin 100000000
+ </Type>
+ </Plugin>
+
+ <Type "load">
+ DataSource "midterm"
+ FailureMax 4
+ Hits 3
+ Hysteresis 3
+ </Type>
+ </Host>
+ </Plugin>
+
+There are basically two types of configuration statements: The C<Host>,
+C<Plugin>, and C<Type> blocks select the value for which a threshold should be
+configured. The C<Plugin> and C<Type> blocks may be specified further using the
+C<Instance> option. You can combine the block by nesting the blocks, though
+they must be nested in the above order, i.e. C<Host> may contain either
+C<Plugin> and C<Type> blocks, C<Plugin> may only contain C<Type> blocks and
+C<Type> may not contain other blocks. If multiple blocks apply to the same
+value the most specific block is used.
+
+The other statements specify the threshold to configure. They B<must> be
+included in a C<Type> block. Currently the following statements are recognized:
+
+=over 4
+
+=item B<FailureMax> I<Value>
+
+=item B<WarningMax> I<Value>
+
+Sets the upper bound of acceptable values. If unset defaults to positive
+infinity. If a value is greater than B<FailureMax> a B<FAILURE> notification
+will be created. If the value is greater than B<WarningMax> but less than (or
+equal to) B<FailureMax> a B<WARNING> notification will be created.
+
+=item B<FailureMin> I<Value>
+
+=item B<WarningMin> I<Value>
+
+Sets the lower bound of acceptable values. If unset defaults to negative
+infinity. If a value is less than B<FailureMin> a B<FAILURE> notification will
+be created. If the value is less than B<WarningMin> but greater than (or equal
+to) B<FailureMin> a B<WARNING> notification will be created.
+
+=item B<DataSource> I<DSName>
+
+Some data sets have more than one "data source". Interesting examples are the
+C<if_octets> data set, which has received (C<rx>) and sent (C<tx>) bytes and
+the C<disk_ops> data set, which holds C<read> and C<write> operations. The
+system load data set, C<load>, even has three data sources: C<shortterm>,
+C<midterm>, and C<longterm>.
+
+Normally, all data sources are checked against a configured threshold. If this
+is undesirable, or if you want to specify different limits for each data
+source, you can use the B<DataSource> option to have a threshold apply only to
+one data source.
+
+=item B<Invert> B<true>|B<false>
+
+If set to B<true> the range of acceptable values is inverted, i.e. values
+between B<FailureMin> and B<FailureMax> (B<WarningMin> and B<WarningMax>) are
+not okay. Defaults to B<false>.
+
+=item B<Persist> B<true>|B<false>
+
+Sets how often notifications are generated. If set to B<true> one notification
+will be generated for each value that is out of the acceptable range. If set to
+B<false> (the default) then a notification is only generated if a value is out
+of range but the previous value was okay.
+
+This applies to missing values, too: If set to B<true> a notification about a
+missing value is generated once every B<Interval> seconds. If set to B<false>
+only one such notification is generated until the value appears again.
+
+=item B<PersistOK> B<true>|B<false>
+
+Sets how OKAY notifications act. If set to B<true> one notification will be
+generated for each value that is in the acceptable range. If set to B<false>
+(the default) then a notification is only generated if a value is in range but
+the previous value was not.
+
+=item B<Percentage> B<true>|B<false>
+
+If set to B<true>, the minimum and maximum values given are interpreted as
+percentage value, relative to the other data sources. This is helpful for
+example for the "df" type, where you may want to issue a warning when less than
+5E<nbsp>% of the total space is available. Defaults to B<false>.
+
+=item B<Hits> I<Value>
+
+Sets the number of occurrences which the threshold must be raised before to
+dispatch any notification or, in other words, the number of B<Interval>s
+that the threshold must be match before dispatch any notification.
+
+=item B<Hysteresis> I<Value>
+
+Sets the hysteresis value for threshold. The hysteresis is a method to prevent
+flapping between states, until a new received value for a previously matched
+threshold down below the threshold condition (B<WarningMax>, B<FailureMin> or
+everything else) minus the hysteresis value, the failure (respectively warning)
+state will be keep.
+
+=item B<Interesting> B<true>|B<false>
+
+If set to B<true> (the default), a notification with severity C<FAILURE> will
+be created when a matching value list is no longer updated and purged from the
+internal cache. When this happens depends on the I<interval> of the value list
+and the global B<Timeout> setting. See the B<Interval> and B<Timeout> settings
+in L<collectd.conf(5)> for details. If set to B<false>, this event will be
+ignored.

+By default, this is disabled. As a special exception, if the plugin name is

+

+
+Sets a plugin-specific interval for collecting metrics. This overrides the
+global B<Interval> setting. If a plugin provides own support for specifying an
+interval, that setting will take precedence.

Include "/etc/collectd.d/*.conf"
+Starting with version 5.3, this may also be a block in which further options
+affecting the behavior of B<Include> may be specified. The following option is
+currently allowed:

+ <Include "/etc/collectd.d">
+ Filter "*.conf"
+ </Include>
+

+
+=item B<Filter> I<pattern>
+
+If the C<fnmatch> function is available on your system, a shell-like wildcard
+I<pattern> may be specified to filter which files to include. This may be used
+in combination with recursively including a directory to easily be able to
+arbitrarily mix configuration files and other documents (e.g. README files).
+The given example is similar to the first example above but includes all files
+matching C<*.conf> in any subdirectory of C</etc/collectd.d>:
+
+ Include "/etc/collectd.d" "*.conf"

If more than one files are included by a single B<Include> option, the files
will be included in lexicographical order (as defined by the C<strcmp>
function). Thus, you can e.E<nbsp>g. use numbered prefixes to specify the
this setting uses iterations, the maximum allowed time without update depends
on the I<Interval> information contained in each value list. This is used in
the I<Threshold> configuration to dispatch notifications about missing values,
-see L<"THRESHOLD CONFIGURATION"> below.
+see L<collectd-threshold(5)> for details.
=item B<ReadThreads> I<Num>
Number of threads to start for reading plugins. The default value is 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.

+=item B<WriteThreads> I<Num>
+
+Number of threads to start for dispatching value lists to write plugins. The
+default value is B<5>, but you may want to increase this if you have more than
+five plugins that may take relatively long to write to.
=item B<Hostname> I<Name>
If B<Hostname> is determined automatically this setting controls whether or not
the daemon should try to figure out the "fully qualified domain name", FQDN.
-This is done using a lookup of the name returned by C<gethostname>.
-
-Using this feature (i.E<nbsp>e. setting this option to B<true>) is recommended.
-However, to preserve backwards compatibility the default is set to B<false>.
-The sample config file that is installed with C<makeE<nbsp>install> includes a
-line which sets this option, though, so that default installations will have
-this setting enabled.

+=head2 Plugin C<aggregation>
+
+The I<Aggregation plugin> makes it possible to aggregate several values into
+one using aggregation functions such as I<sum>, I<average>, I<min> and I<max>.
+This can be put to a wide variety of uses, e.g. average and total CPU
+statistics for your entire fleet.
+
+The grouping is powerful but, as with many powerful tools, may be a bit
+difficult to wrap your head around. The grouping will therefore be
+demonstrated using an example: The average and sum of the CPU usage across
+all CPUs of each host is to be calculated.
+
+To select all the affected values for our example, set C<Plugin cpu> and
+C<Type cpu>. The other values are left unspecified, meaning "all values". The
+I<Host>, I<Plugin>, I<PluginInstance>, I<Type> and I<TypeInstance> options
+work as if they were specified in the C<WHERE> clause of an C<SELECT> SQL
+statement.
+
+ Plugin "cpu"
+ Type "cpu"
+
+Although the I<Host>, I<PluginInstance> (CPU number, i.e. 0, 1, 2, ...) and
+I<TypeInstance> (idle, user, system, ...) fields are left unspecified in the
+example, the intention is to have a new value for each host / type instance
+pair. This is achieved by "grouping" the values using the C<GroupBy> option.
+It can be specified multiple times to group by more than one field.
+
+ GroupBy "Host"
+ GroupBy "TypeInstance"
+
+We do neither specify nor group by I<plugin instance> (the CPU number), so all
+metrics that differ in the CPU number only will be aggregated. Each
+aggregation needs I<at least one> such field, otherwise no aggregation would
+take place.
+
+The full example configuration looks like this:
+
+ <Plugin "aggregation">
+ <Aggregation>
+ Plugin "cpu"
+ Type "cpu"
+
+ GroupBy "Host"
+ GroupBy "TypeInstance"
+
+ CalculateSum true
+ CalculateAverage true
+ </Aggregation>
+ </Plugin>
+
+There are a couple of limitations you should be aware of:
+
+=over 4
+
+=item
+
+The I<Type> cannot be left unspecified, because it is not reasonable to add
+apples to oranges. Also, the internal lookup structure won't work if you try
+to group by type.
+
+=item
+
+There must be at least one unspecified, ungrouped field. Otherwise nothing
+will be aggregated.
+
+=back
+
+As you can see in the example above, each aggregation has its own
+B<Aggregation> block. You can have multiple aggregation blocks and aggregation
+blocks may match the same values, i.e. one value list can update multiple
+aggregations. The following options are valid inside B<Aggregation> blocks:
+
+=over 4
+
+=item B<Host> I<Host>
+
+=item B<Plugin> I<Plugin>
+
+=item B<PluginInstance> I<PluginInstance>
+
+=item B<Type> I<Type>
+
+=item B<TypeInstance> I<TypeInstance>
+
+Selects the value lists to be added to this aggregation. B<Type> must be a
+valid data set name, see L<types.db(5)> for details.
+
+If the string starts with and ends with a slash (C</>), the string is
+interpreted as a I<regular expression>. The regex flavor used are POSIX
+extended regular expressions as described in L<regex(7)>. Example usage:
+
+ Host "/^db[0-9]\\.example\\.com$/"
+
+=item B<GroupBy> B<Host>|B<Plugin>|B<PluginInstance>|B<TypeInstance>
+
+Group valued by the specified field. The B<GroupBy> option may be repeated to
+group by multiple fields.
+
+=item B<SetHost> I<Host>
+
+=item B<SetPlugin> I<Plugin>
+
+=item B<SetPluginInstance> I<PluginInstance>
+
+=item B<SetTypeInstance> I<TypeInstance>
+
+Sets the appropriate part of the identifier to the provided string.
+
+The I<PluginInstance> should include the placeholder C<%{aggregation}> which
+will be replaced with the aggregation function, e.g. "average". Not including
+the placeholder will result in duplication warnings and/or messed up values if
+more than one aggregation function are enabled.
+
+The following example calculates the average usage of all "even" CPUs:
+
+ <Plugin "aggregation">
+ <Aggregation>
+ Plugin "cpu"
+ PluginInstance "/[0,2,4,6,8]$/"
+ Type "cpu"
+
+ SetPlugin "cpu"
+ SetPluginInstance "even-%{aggregation}"
+
+ GroupBy "Host"
+ GroupBy "TypeInstance"
+
+ CalculateAverage true
+ </Aggregation>
+ </Plugin>
+
+This will create the files:
+
+=over 4
+
+=item
+
+foo.example.com/cpu-even-average/cpu-idle
+

+
+foo.example.com/cpu-even-average/cpu-system

+=head2 Plugin C<amqp>
+
+The I<AMQMP plugin> can be used to communicate with other instances of
+I<collectd> or third party applications using an AMQP message broker. Values
+are sent to or received from the broker, which handles routing, queueing and
+possibly filtering or messages.
+
+ <Plugin "amqp">
+ # Send values to an AMQP broker
+ <Publish "some_name">
+ Host "localhost"
+ Port "5672"
+ VHost "/"
+ User "guest"
+ Password "guest"
+ Exchange "amq.fanout"
+ # ExchangeType "fanout"
+ # RoutingKey "collectd"
+ # Persistent false
+ # Format "command"
+ # StoreRates false
+ # GraphitePrefix "collectd."
+ # GraphiteEscapeChar "_"
+ # GraphiteSeparateInstances false
+ # GraphiteAlwaysAppendDS false
+ </Publish>
+
+ # Receive values from an AMQP broker
+ <Subscribe "some_name">
+ Host "localhost"
+ Port "5672"
+ VHost "/"
+ User "guest"
+ Password "guest"
+ Exchange "amq.fanout"
+ # ExchangeType "fanout"
+ # Queue "queue_name"
+ # RoutingKey "collectd.#"
+ </Subscribe>
+ </Plugin>
+
+The plugin's configuration consists of a number of I<Publish> and I<Subscribe>
+blocks, which configure sending and receiving of values respectively. The two
+blocks are very similar, so unless otherwise noted, an option can be used in
+either block. The name given in the blocks starting tag is only used for
+reporting messages, but may be used to support I<flushing> of certain
+I<Publish> blocks in the future.
+
+=over 4

+
+Hostname or IP-address of the AMQP broker. Defaults to the default behavior of
+the underlying communications library, I<rabbitmq-c>, which is "localhost".
+
+=item B<Port> I<Port>
+
+Service name or port number on which the AMQP broker accepts connections. This
+argument must be a string, even if the numeric form is used. Defaults to
+"5672".
+
+=item B<VHost> I<VHost>
+
+Name of the I<virtual host> on the AMQP broker to use. Defaults to "/".

+
+Credentials used to authenticate to the AMQP broker. By default "guest"/"guest"
+is used.
+
+=item B<Exchange> I<Exchange>
+
+In I<Publish> blocks, this option specifies the I<exchange> to send values to.
+By default, "amq.fanout" will be used.
+
+In I<Subscribe> blocks this option is optional. If given, a I<binding> between
+the given exchange and the I<queue> is created, using the I<routing key> if
+configured. See the B<Queue> and B<RoutingKey> options below.
+
+=item B<ExchangeType> I<Type>
+
+If given, the plugin will try to create the configured I<exchange> with this
+I<type> after connecting. When in a I<Subscribe> block, the I<queue> will then
+be bound to this exchange.
+
+=item B<Queue> I<Queue> (Subscribe only)
+
+Configures the I<queue> name to subscribe to. If no queue name was configures
+explicitly, a unique queue name will be created by the broker.
+
+=item B<RoutingKey> I<Key>
+
+In I<Publish> blocks, this configures the routing key to set on all outgoing
+messages. If not given, the routing key will be computed from the I<identifier>
+of the value. The host, plugin, type and the two instances are concatenated
+together using dots as the separator and all containing dots replaced with
+slashes. For example "collectd.host/example/com.cpu.0.cpu.user". This makes it
+possible to receive only specific values using a "topic" exchange.
+
+In I<Subscribe> blocks, configures the I<routing key> used when creating a
+I<binding> between an I<exchange> and the I<queue>. The usual wildcards can be
+used to filter messages when using a "topic" exchange. If you're only
+interested in CPU statistics, you could use the routing key "collectd.*.cpu.#"
+for example.
+
+=item B<Persistent> B<true>|B<false> (Publish only)
+
+Selects the I<delivery method> to use. If set to B<true>, the I<persistent>
+mode will be used, i.e. delivery is guaranteed. If set to B<false> (the
+default), the I<transient> delivery mode will be used, i.e. messages may be
+lost due to high load, overflowing queues or similar issues.
+
+=item B<Format> B<Command>|B<JSON>|B<Graphite> (Publish only)
+
+Selects the format in which messages are sent to the broker. If set to
+B<Command> (the default), values are sent as C<PUTVAL> commands which are
+identical to the syntax used by the I<Exec> and I<UnixSock plugins>. In this
+case, the C<Content-Type> header field will be set to C<text/collectd>.
+
+If set to B<JSON>, the values are encoded in the I<JavaScript Object Notation>,
+an easy and straight forward exchange format. The C<Content-Type> header field
+will be set to C<application/json>.
+
+If set to B<Graphite>, values are encoded in the I<Graphite> format, which is
+"<metric> <value> <timestamp>\n". The C<Content-Type> header field will be set to
+C<text/graphite>.
+
+A subscribing client I<should> use the C<Content-Type> header field to
+determine how to decode the values. Currently, the I<AMQP plugin> itself can
+only decode the B<Command> format.
+
+=item B<StoreRates> B<true>|B<false> (Publish only)
+
+Determines whether or not C<COUNTER>, C<DERIVE> and C<ABSOLUTE> data sources
+are converted to a I<rate> (i.e. a C<GAUGE> value). If set to B<false> (the
+default), no conversion is performed. Otherwise the conversion is performed
+using the internal value cache.
+
+Please note that currently this option is only used if the B<Format> option has
+been set to B<JSON>.
+
+=item B<GraphitePrefix> (Publish and B<Format>=I<Graphite> only)
+
+A prefix can be added in the metric name when outputting in the I<Graphite> format.
+It's added before the I<Host> name.
+Metric name will be "<prefix><host><postfix><plugin><type><name>"
+
+=item B<GraphitePostfix> (Publish and B<Format>=I<Graphite> only)
+
+A postfix can be added in the metric name when outputting in the I<Graphite> format.

+Metric name will be "<prefix><host><postfix><plugin><type><name>"
+
+=item B<GraphiteEscapeChar> (Publish and B<Format>=I<Graphite> only)
+
+Specify a character to replace dots (.) in the host part of the metric name.
+In I<Graphite> metric name, dots are used as separators between different
+metric parts (host, plugin, type).
+Default is "_" (I<Underscore>).
+
+=item B<GraphiteSeparateInstances> B<true>|B<false>
+
+If set to B<true>, the plugin instance and type instance will be in their own
+path component, for example C<host.cpu.0.cpu.idle>. If set to B<false> (the
+default), the plugin and plugin instance (and likewise the type and type
+instance) are put into one component, for example C<host.cpu-0.cpu-idle>.
+
+=item B<GraphiteAlwaysAppendDS> B<true>|B<false>
+
+If set to B<true>, append the name of the I<Data Source> (DS) to the "metric"
+identifier. If set to B<false> (the default), this is only done when there is
+more than one DS.

=head2 Plugin C<apache>
To configure the C<apache>-plugin you first need to configure the Apache

number of currently connected clients. This field is also supported.
-The following options are accepted by the C<apache>-plugin:
+The configuration of the I<Apache> plugin consists of one or more

+
+Values are submitted to I<Sorted Sets>, using the metric name as the key, and
+the timestamp as the score. Retrieving a date range can then be done using the
+C<ZRANGEBYSCORE> I<Redis> command. Additionnally, all the identifiers of these

+retrieved using the C<SMEMBERS> I<Redis> command. See
+L<http://redis.io/commands#sorted_set> and L<http://redis.io/commands#set> for
+details.
+
+The information shown in the synopsis above is the I<default configuration>
+which is used by the plugin if no configuration is present.

+=item B<Host> I<Hostname>
+
+The B<Host> option is the hostname or IP-address where the I<Redis> instance is
+running on.
+
+=item B<Port> I<Port>
+
+The B<Port> option is the TCP port on which the Redis instance accepts

+=head1 NAME
+
+collectdctl - Control interface for collectd
+
+=head1 SYNOPSIS
+
+collectdctl I<[options]> I<E<lt>commandE<gt>> I<[command options]>
+
+=head1 DESCRIPTION
+
+collectdctl provides a control interface for collectd, which may be used to
+interact with the daemon using the C<unixsock plugin>.
+
+=head1 OPTIONS
+
+collectdctl supports the following options:
+
+=over 4
+
+=item B<-s> I<socket>
+
+Path to the UNIX socket opened by collectd's C<unixsock plugin>.
+Default: /var/run/collectd-unixsock
+
+=item B<-h>
+
+Display usage information and exit.
+
+=back
+
+=head1 AVAILABLE COMMANDS
+
+The following commands are supported:
+
+=over 4
+
+=item B<getval> I<E<lt>identifierE<gt>>
+
+Query the latest collected value identified by the specified
+I<E<lt>identifierE<gt>> (see below). The value-list associated with that
+data-set is returned as a list of key-value-pairs, each on its own line. Keys
+and values are separated by the equal sign (C<=>).
+
+=item B<flush> [B<timeout=>I<E<lt>secondsE<gt>>] [B<plugin=>I<E<lt>nameE<gt>>]
+[B<identifier=>I<E<lt>idE<gt>>]
+
+Flush the daemon. This is useful, e.E<nbsp>g., to make sure that the latest
+values have been written to the respective RRD file before graphing them or
+copying them to somewhere else.
+
+The following options are supported by the flush command:
+
+=over 4
+
+=item B<timeout=>I<E<lt>secondsE<gt>>
+
+Flush values older than the specified timeout (in seconds) only.
+
+=item B<plugin=>I<E<lt>nameE<gt>>
+
+Flush the specified plugin only. I.E<nbsp>e., data cached by the specified
+plugin is written to disk (or network or whatever), if the plugin supports
+that operation.
+
+Example: B<rrdtool>.
+
+=item B<identifier=>I<E<lt>idE<gt>>
+
+If this option is present, only the data specified by the specified identifier
+(see below) will be flushed. Note that this option is not supported by all
+plugins (e.E<nbsp>g., the C<network> plugin does not support this).
+
+=back
+
+The B<plugin> and B<identifier> options may be specified more than once. In
+that case, all combinations of specified plugins and identifiers will be
+flushed only.
+
+=item B<listval>
+
+Returns a list of all values (by their identifier) available to the
+C<unixsock> plugin. Each value is printed on its own line. I.E<nbsp>e., this
+command returns a list of valid identifiers that may be used with the other
+commands.
+
+=item B<putval> I<E<lt>identifierE<gt>> [B<interval=>I<E<lt>secondsE<gt>>]
+I<E<lt>value-list(s)E<gt>>
+
+Submit one or more values (identified by I<E<lt>identifierE<gt>>, see below)
+to the daemon which will then dispatch them to the write plugins. B<interval>
+specifies the interval (in seconds) used to collect the values following that
+option. It defaults to the default of the running collectd instance receiving
+the data. Multiple I<E<lt>value-list(s)E<gt>> (see below) may be specified.
+Each of them will be submitted to the daemon. The values have to match the
+data-set definition specified by the type as given in the identifier (see
+L<types.db(5)> for details).
+
+=back
+
+=head1 IDENTIFIERS
+
+An identifier has the following format:
+
+[I<hostname>/]I<plugin>[-I<plugin_instance>]/I<type>[-I<type_instance>]
+
+Examples:
+ somehost/cpu-0/cpu-idle
+ uptime/uptime
+ otherhost/memory/memory-used
+
+Hostname defaults to the local (non-fully qualified) hostname if omitted. No
+error is returned if the specified identifier does not exist (this is a
+limitation in the C<libcollectdclient> library).
+
+=head1 VALUE-LIST
+
+A value list describes one data-set as handled by collectd. It is a colon
+(C<:>) separated list of the time and the values. Each value is either given
+as an integer if the data-type is a counter, or as a double if the data-type
+is a gauge value. A literal C<U> is interpreted as an undefined gauge value.
+The number of values and the data-types have to match the type specified in
+the identifier (see L<types.db(5)> for details). The time is specified as
+epoch (i.E<nbsp>e., standard UNIX time) or as a literal C<N> which will be
+interpreted as now.
+
+=head1 EXAMPLES
+
+=over 4
+
+=item C<collectdctl flush plugin=rrdtool identifier=somehost/cpu-0/cpu-wait>
+
+Flushes all CPU wait RRD values of the first CPU of the local host.
+I.E<nbsp>e., writes all pending RRD updates of that data-source to disk.
+
+=item C<for ident in `collectdctl listval | grep users/users`; do
+ collectdctl getval $ident;
+ done>
+
+Query the latest number of logged in users on all hosts known to the local
+collectd instance.

- libiptc (IPTables Chains) in collectd
-=======================================
-http://netfilter.org/
-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.
