- conntrack
Number of nf_conntrack entries.
+ - contextswitch
+ Number of context switches done by the operating system.
+
- cpu
CPU utilization: Time spent in the system, user, nice, idle, and related
states.
MySQL server statistics: Commands issued, handlers triggered, thread
usage, query cache utilization and traffic/octets sent and received.
+ - netapp
+ Plugin to query performance values from a NetApp storage system using the
+ “Manage ONTAP” SDK provided by NetApp.
+
- netlink
Very detailed Linux network interface and routing statistics. You can get
(detailed) information on interfaces, qdiscs, classes, and, if you can
- protocols
Counts various aspects of network protocols such as IP, TCP, UDP, etc.
+ - python
+ The python plugin implements a Python interpreter into collectd. This
+ makes it possible to write plugins in Python which are executed by
+ collectd without the need to start a heavy interpreter every interval.
+ See collectd-python(5) for details.
+
- rrdcached
RRDtool caching daemon (RRDcacheD) statistics.
you can easily do weird stuff with the plugins we didn't dare think of
;) See collectd-perl(5).
+ - python
+ It's possible to implement write plugins in Python using the python
+ plugin. See collectd-python(5) for details.
+
- rrdcached
Output to round-robin-database (RRD) files using the RRDtool caching
daemon (RRDcacheD) - see rrdcached(1). That daemon provides a general
Log messages are propagated to plugins written in Perl as well.
See collectd-perl(5).
+ - python
+ It's possible to implement log plugins in Python using the python plugin.
+ See collectd-python(5) for details.
+
- syslog
Logs to the standard UNIX logging mechanism, syslog.
Notifications are propagated to plugins written in Perl as well.
See collectd-perl(5).
+ - python
+ It's possible to implement notification plugins in Python using the
+ python plugin. See collectd-python(5) for details.

* Value processing can be controlled using the "filter chain" infrastructure
and "matches" and "targets". The following plugins are available:
Unsurprisingly used by the `mysql' plugin.
<http://dev.mysql.com/>
+ * libnatapp (optional)
+ Required for the “netapp” plugin.
+ This library is part of the “Manage ONTAP SDK” published by NetApp.
+
* libnetlink (optional)
Used, obviously, for the `netlink' plugin.
<http://www.linuxfoundation.org/en/Net:Iproute2>
The PostgreSQL C client library used by the `postgresql' plugin.
<http://www.postgresql.org/>
+ * libpython (optional)
+ Used by the `python' plugin. Currently, only 2.3 ≦ Python < 3 is supported.
+ <http://www.python.org/>
+
+ * librouteros (optional)
+ Used by the `routeros' plugin to connect to a device running `RouterOS'.
+ <http://verplant.org/librouteros/>
+
* 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,

-=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 IDENTIFIERS
-
-The values in the collectd are identified using an five-tuple (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);

- {
- cluck ("Need `host', `plugin' and `type'");
- return;
- }
-

+=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 IDENTIFIERS
+
+The values in the collectd are identified using an five-tuple (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 NAME
+
+collectd-python - Documentation of collectd's C<python plugin>
+
+=head1 SYNOPSIS
+
+ <LoadPlugin python>
+ Globals true
+ </LoadPlugin>
+ # ...
+ <Plugin python>
+ ModulePath "/path/to/your/python/modules"
+ LogTraces true
+ Interactive true
+ Import "spam"
+
+ <Module spam>
+ spam "wonderful" "lovely"
+ </Module>
+ </Plugin>
+
+=head1 DESCRIPTION
+
+The C<python plugin> embeds a Python-interpreter into collectd and provides an
+interface to collectd's plugin system. This makes it possible to write plugins
+for collectd in Python. This is a lot more efficient than executing a
+Python-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.
+
+Currently only I<Python 2> is supported and at least I<version 2.3> is
+required.
+
+=head1 CONFIGURATION
+
+=over 4
+
+=item B<LoadPlugin> I<Plugin>
+
+Loads the Python plugin I<Plugin>. Unlike most other LoadPlugin lines, this one
+should be a block containing the line "Globals true". This will cause collectd
+to export the name of all objects in the python interpreter for all plugins to
+see. If you don't do this or your platform does not support it, the embeded
+interpreter will start anywa but you won't be able to load certain python
+modules, e.g. "time".
+
+=item B<Encoding> I<Name>
+
+The default encoding for Unicode objects you pass to collectd. If you omit this
+option it will default to B<ascii> on I<Python 2> and B<utf-8> on I<Python 3>.
+This is hardcoded in Python and will ignore everything else, including your
+locale.
+
+=item B<ModulePath> I<Name>
+
+Appends I<Name> to B<sys.path>. You won't be able to import any scripts you
+wrote unless they are located in one of the directories in this list. Please
+note that it only has effect on plugins loaded after this option. You can
+use multiple B<ModulePath> lines to add more than one directory.
+
+=item B<LogTraces> I<bool>
+
+If a python script throws an exception it will be logged by collectd with the
+name of the exception and the message. If you set this option to true it will
+also log the full stacktrace just like the default output of an interactive
+python interpreter. This should probably be set to false most of the time but
+is very useful for development and debugging of new modules.
+
+=item B<Interactive> I<bool>
+
+This option will cause the module to launch an interactive python interpreter
+that reads from and writes to the terminal. Note that collectd will terminate
+right after starting up if you try to run it as a daemon while this option is
+enabled to make sure to start collectd with the B<-f> option.
+
+The B<collectd> module is I<not> imported into the interpreter's globals. You
+have to do it manually. Be sure to read the help text of the module, it can be
+used as a reference guide during coding.
+
+This interactive session will behave slightly differently from a daemonized
+collectd script as well as from a normal python interpreter:
+
+=over 4
+
+=item
+
+B<1.> collectd will try to import the B<readline> module to give you a decent
+way of entering your commands. The daemonized collectd won't do that.
+
+=item
+
+B<2.> collectd will block I<SIGINT>. Pressing I<Ctrl+C> will usually cause
+collectd to shut down. This would be problematic in an interactive session,
+therefore this signal will be blocked. You can still use it to interrupt
+syscalls like sleep and pause but it won't generate a I<KeyboardInterrupt>
+exception either.
+
+To quit collectd send I<EOF> (press I<Ctrl+D> at the beginning of a new line).
+
+=back
+
+=item E<lt>B<Module> I<Name>E<gt> block
+
+This block may be used to pass on configuration settings to a Python module.
+The configuration is converted into an instance of the B<Config> class which is
+passed to the registered configuration callback. See below for details about
+the B<Config> class and how to register callbacks.
+
+The I<name> identifies the callback.
+
+=back
+
+=head1 WRITING YOUR OWN PLUGINS
+
+Writing your own plugins is quite simple. collectd manages plugins by means of
+B<dispatch functions> which call the appropriate B<callback functions>
+registered by the plugins. Any plugin basically consists of the implementation
+of these callback functions and initializing code which registers the
+functions with collectd. See the section "EXAMPLES" below for a really basic
+example. The following types of B<callback functions> are known to collectd
+(all of them are optional):
+
+=over 4
+
+=item configuration functions
+
+This type of functions is called during configuration if an appropriate
+B<Module> block has been encountered. It is called once for each B<Module>
+block which matches the name of the callback as provided with the
+B<register_config> method - see below.
+
+Python thread support has not been initialized at this point so do not use any
+threading functions here!
+
+=item init functions
+
+This type of functions is called once after loading the module and before any
+calls to the read and write functions. It should be used to initialize the
+internal state of the plugin (e.E<nbsp>g. open sockets, ...). This is the
+earliest point where you may use threads.
+
+=item read functions
+
+This type of function is used to collect the actual data. It is called once
+per interval (see the B<Interval> configuration option of collectd). Usually
+it will call B<plugin_dispatch_values> to dispatch the values to collectd
+which will pass them on to all registered B<write functions>. If this function
+throws any kind of exception the plugin will be skipped for an increasing
+amount of time until it returns normally again.
+
+=item write functions
+
+This type of function is used to write the dispatched values. It is called
+once for every value that was dispatched by any plugin.
+
+=item flush functions
+
+This type of function is used to flush internal caches of plugins. It is
+usually triggered by the user only. Any plugin which caches data before
+writing it to disk should provide this kind of callback function.
+
+=item log functions
+
+This type of function is used to pass messages of plugins or the daemon itself
+to the user.
+
+=item notification function
+
+This type of function is used to act upon notifications. In general, a
+notification is a status message that may be associated with a data instance.
+Usually, a notification is generated by the daemon if a configured threshold
+has been exceeded (see the section "THRESHOLD CONFIGURATION" in
+L<collectd.conf(5)> for more details), but any plugin may dispatch
+notifications as well.
+
+=item shutdown functions
+
+This type of function is called once before the daemon shuts down. It should
+be used to clean up the plugin (e.g. close sockets, ...).
+
+=back
+
+Any function (except log functions) may set throw an exception in case of any
+errors. The exception will be passed on to the user using collectd's logging
+mechanism. If a log callback throws an exception it will be printed to standard
+error instead.
+
+See the documentation of the various B<register_> methods in the section
+"FUNCTIONS" below for the number and types of arguments passed to each
+B<callback function>. This section also explains how to register B<callback
+functions> with collectd.
+
+To enable a module, copy it to a place where Python can find it (i.E<nbsp>e. a
+directory listed in B<sys.path>) just as any other Python plugin and add
+an appropriate B<Import> option to the configuration file. After restarting
+collectd you're done.
+
+=head1 CLASSES
+
+The following complex types are used to pass values between the Python plugin
+and collectd:
+
+=head2 Config
+
+The Config class is an object which keeps the informations provided in the
+configuration file. The sequence of children keeps one entry for each
+configuration option. Each such entry is another Config instance, which
+may nest further if nested blocks are used.
+
+ class Config(object)

+This represents a piece of collectd's config file. It is passed to scripts with
+config callbacks (see B<register_config>) and is of little use if created
+somewhere else.
+
+It has no methods beyond the bare minimum and only exists for its data members.
+
+Data descriptors defined here:

+
+=item parent
+
+This represents the parent of this node. On the root node
+of the config tree it will be None.
+
+=item key
+
+This is the keyword of this item, i.e. the first word of any given line in the
+config file. It will always be a string.
+
+=item values
+
+This is a tuple (which might be empty) of all value, i.e. words following the
+keyword in any given line in the config file.
+
+Every item in this tuple will be either a string or a float or a boolean,
+depending on the contents of the configuration file.
+
+=item children
+
+This is a tuple of child nodes. For most nodes this will be empty. If this node
+represents a block instead of a single line of the config file it will contain
+all nodes in this block.

+
+=head2 PluginData
+
+This should not be used directly but it is the base class for both Values and
+Notification. It is used to identify the source of a value or notification.
+
+ class PluginData(object)
+
+This is an internal class that is the base for Values and Notification. It is
+pretty useless by itself and was therefore not exported to the collectd module.
+
+Data descriptors defined here:
+
+=over 4
+
+=item host
+
+The hostname of the host this value was read from. For dispatching this can be
+set to an empty string which means the local hostname as defined in
+collectd.conf.
+
+=item plugin
+
+The name of the plugin that read the data. Setting this member to an empty
+string will insert "python" upon dispatching.
+
+=item plugin_instance
+
+Plugin instance string. May be empty.
+
+=item time
+
+This is the Unix timestamp of the time this value was read. For dispatching
+values this can be set to zero which means "now". This means the time the value
+is actually dispatched, not the time it was set to 0.
+
+=item type
+
+The type of this value. This type has to be defined in your I<types.db>.
+Attempting to set it to any other value will raise a I<TypeError> exception.
+Assigning a type is mandatory, calling dispatch without doing so will raise a
+I<RuntimeError> exception.
+
+=item type_instance
+
+Type instance string. May be empty.
+

+
+=head2 Values
+
+A Value is an object which features a sequence of values. It is based on then
+I<PluginData> type and uses its members to identify the values.
+
+ class Values(PluginData)
+
+A Values object used for dispatching values to collectd and receiving values
+from write callbacks.

+
+Methods defined here:
+
+=over 4
+
+=item B<dispatch>([type][, values][, plugin_instance][, type_instance][, plugin][, host][, time][, interval]) -> None.
+
+Dispatch this instance to the collectd process. The object has members for each
+of the possible arguments for this method. For a detailed explanation of these
+parameters see the member of the same same.
+
+If you do not submit a parameter the value saved in its member will be
+submitted. If you do provide a parameter it will be used instead, without
+altering the member.
+
+=item B<write>([destination][, type][, values][, plugin_instance][, type_instance][, plugin][, host][, time][, interval]) -> None.
+
+Write this instance to a single plugin or all plugins if "destination" is
+omitted. This will bypass the main collectd process and all filtering and
+caching. Other than that it works similar to "dispatch". In most cases
+"dispatch" should be used instead of "write".
+
+=back
+
+Data descriptors defined here:
+
+=over 4
+
+=item interval
+
+The interval is the timespan in seconds between two submits for the same data
+source. This value has to be a positive integer, so you can't submit more than
+one value per second. If this member is set to a non-positive value, the
+default value as specified in the config file will be used (default: 10).
+
+If you submit values more often than the specified interval, the average will
+be used. If you submit less values, your graphs will have gaps.
+
+=item values
+
+These are the actual values that get dispatched to collectd. It has to be a
+sequence (a tuple or list) of numbers. The size of the sequence and the type of
+its content depend on the type member your I<types.db> file. For more
+information on this read the L<types.db(5)> manual page.
+
+If the sequence does not have the correct size upon dispatch a I<RuntimeError>
+exception will be raised. If the content of the sequence is not a number, a
+I<TypeError> exception will be raised.
+

+
+=head2 Notification
+
+A notification is an object defining the severity and message of the status
+message as well as an identification of a data instance by means of the members
+of I<PluginData> on which it is based.
+
+class Notification(PluginData)
+The Notification class is a wrapper around the collectd notification.
+It can be used to notify other plugins about bad stuff happening. It works
+similar to Values but has a severity and a message instead of interval
+and time.
+Notifications can be dispatched at any time and can be received with
+register_notification.

+
+The following functions provide the C-interface to Python-modules.
+
+=over 4
+
+=item B<register_*>(I<callback>[, I<data>][, I<name>]) -> identifier
+
+There are eight different register functions to get callback for eight
+different events. With one exception all of them are called as shown above.
+
+=over 4
+
+=item
+
+I<callback> is a callable object that will be called every time the event is
+triggered.
+
+=item
+
+I<data> is an optional object that will be passed back to the callback function
+every time it is called. If you omit this parameter no object is passed back to
+your callback, not even None.
+
+=item
+
+I<name> is an optional identifier for this callback. The default name is
+B<python>.I<module>. I<module> is taken from the B<__module__> attribute of
+your callback function. Every callback needs a unique identifier, so if you
+want to register the same callback multiple time in the same module you need to
+specify a name here. Otherwise it's save to ignore this parameter I<identifier>
+is the full identifier assigned to this callback.
+
+=back
+
+These functions are called in the various stages of the daemon (see the section
+L<"WRITING YOUR OWN PLUGINS"> above) and are passed the following arguments:
+
+=over 4
+
+=item register_config
+
+The only argument passed is a I<Config> object. See above for the layout of this
+data type.
+Note that you can not receive the whole config files this way, only B<Module>
+blocks inside the Python configuration block. Additionally you will only
+receive blocks where your callback identifier matches B<python.>I<blockname>.
+
+=item register_init
+
+The callback will be called without arguments.
+
+=item register_read(callback[, interval][, data][, name]) -> identifier
+
+This function takes an additional parameter: I<interval>. It specifies the
+time between calls to the callback function.
+
+The callback will be called without arguments.
+
+=item register_shutdown
+
+The callback will be called without arguments.
+
+=item register_write
+
+The callback function will be called with one arguments passed, which will be a
+I<Values> object. For the layout of I<Values> see above.
+If this callback function throws an exception the next call will be delayed by
+an increasing interval.
+
+=item register_flush
+
+Like B<register_config> is important for this callback because it determines
+what flush requests the plugin will receive.
+
+The arguments passed are I<timeout> and I<identifier>. I<timeout> indicates
+that only data older than I<timeout> seconds is to be flushed. I<identifier>
+specifies which values are to be flushed.
+
+=item register_log
+
+The arguments are I<severity> and I<message>. The severity is an integer and
+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.
+
+If this callback throws an exception it will B<not> be logged. It will just be
+printed to B<sys.stderr> which usually means silently ignored.
+
+=item register_notification
+
+The only argument passed is a I<Notification> object. See above for the layout of this
+data type.
+
+=back
+
+=item B<unregister_*>(I<identifier>) -> None
+
+Removes a callback or data-set from collectd's internal list of callback
+functions. Every I<register_*> function has an I<unregister_*> function.
+I<identifier> is either the string that was returned by the register function
+or a callback function. The identifier will be constructed in the same way as
+for the register functions.
+
+=item B<flush>(I<plugin[, I<timeout>][, I<identifier>]) -> None
+
+Flush one or all plugins. I<timeout> and the specified I<identifiers> are
+passed on to the registered flush-callbacks. If omitted, the timeout defaults
+to C<-1>. The identifier defaults to None. If the B<plugin> argument has been
+specified, only named plugin will be flushed.
+
+=item B<error>, B<warning>, B<notice>, B<info>, B<debug>(I<message>)
+
+Log a message with the specified severity.
+
+=back
+
+=head1 EXAMPLES
+
+Any Python module will start similar to:
+
+ import collectd
+
+A very simple read function might look like:
+
+ def read(data=None):
+ vl = collectd.Values(type='gauge')
+ vl.plugin='python.spam'
+ vl.dispatch(values=[random.random() * 100])
+
+A very simple write function might look like:
+
+ def write(vl, data=None):
+ for i in vl.values:
+ print "%s (%s): %f" % (vl.plugin, vl.type, i)
+
+To register those functions with collectd:
+
+ collectd.register_read(read);
+ collectd.register_write(write);
+
+See the section L<"CLASSES"> above for a complete documentation of the data
+types used by the read, write and match functions.
+
+=head1 NOTES
+
+=over 4
+
+=item
+
+Please feel free to send in new plugins to collectd's mailinglist at
+E<lt>collectdE<nbsp>atE<nbsp>verplant.orgE<gt> for review and, possibly,
+inclusion in the main distribution. In the latter case, we will take care of
+keeping the plugin up to date and adapting it to new versions of collectd.
+
+Before submitting your plugin, please take a look at
+L<http://collectd.org/dev-info.shtml>.
+
+=back
+
+=head1 CAVEATS
+
+=over 4
+
+=item
+
+collectd is heavily multi-threaded. Each collectd thread accessing the python
+plugin will be mapped to a Python interpreter thread. Any such thread will be
+created and destroyed transparently and on-the-fly.
+
+Hence, any plugin has to be thread-safe if it provides several entry points
+from collectd (i.E<nbsp>e. if it registers more than one callback or if a
+registered callback may be called more than once in parallel).
+
+=item
+
+The Python thread module is initialized just before calling the init callbacks.
+This means you must not use Python's threading module prior to this point. This
+includes all config and possibly other callback as well.
+
+=item
+
+The python plugin exports the internal API of collectd which is considered
+unstable and subject to change at any time. We try hard to not break backwards
+compatibility in the Python API during the life cycle of one major release.
+However, this cannot be guaranteed at all times. Watch out for warnings
+dispatched by the python plugin after upgrades.
+
+=back
+
+=head1 KNOWN BUGS
+
+=over 4
+
+=item
+
+This plugin is not compatible with python3. Trying to compile it with python3
+will fail because of the ways string, unicode and bytearray bahavior was
+changed.
+
+=item
+
+Not all aspects of the collectd API are accessible from python. This includes
+but is not limited to meta-data, filters and data sets.

+=head3 The VolumePerf block
+
+This will collect various performance data about the individual volumes.
+
+You can select which data to collect about which volume using the following
+options. They follow the standard ignorelist semantic.
+
+B<Note:> To get this data the collectd user needs the
+I<api-perf-object-get-instances> capability.
+
+=over 4
+
+=item B<Interval> I<Seconds>
+
+Collect volume performance data every I<Seconds> seconds.
+
+=item B<GetIO> I<Volume>
+
+=item B<GetOps> I<Volume>
+
+=item B<GetLatency> I<Volume>
+
+Select the given volume for IO, operations or latency statistics collection.
+The argument is the name of the volume without the C</vol/> prefix.
+
+Since the standard ignorelist functionality is used here, you can use a string
+starting and ending with a slash to specify regular expression matching: To
+match the volumes "vol0", "vol2" and "vol7", you can use this regular
+expression:
+
+ GetIO "/^vol[027]$/"
+
+If no regular expression is specified, an exact match is required. Both,
+regular and exact matching are case sensitive.
+
+If no volume was specified at all for either of the three options, that data
+will be collected for all available volumes.
+
+=item B<IgnoreSelectedIO> B<true>|B<false>
+
+=item B<IgnoreSelectedOps> B<true>|B<false>
+
+=item B<IgnoreSelectedLatency> B<true>|B<false>
+
+When set to B<true>, the volumes selected for IO, operations or latency
+statistics collection will be ignored and the data will be collected for all
+other volumes.
+
+When set to B<false>, data will only be collected for the specified volumes and
+all other volumes will be ignored.
+
+If no volumes have been specified with the above B<Get*> options, all volumes
+will be collected regardless of the B<IgnoreSelected*> option.
+
+Defaults to B<false>
+
+=back
+
+=head3 The VolumeUsage block
+
+This will collect capacity data about the individual volumes.
+
+B<Note:> To get this data the collectd user needs the I<api-volume-list-info>
+capability.
+
+=over 4
+
+=item B<Interval> I<Seconds>
+
+Collect volume usage statistics every I<Seconds> seconds.
+
+=item B<GetCapacity> I<VolumeName>
+
+The current capacity of the volume will be collected. This will result in two
+to four value lists, depending on the configuration of the volume. All data
+sources are of type "df_complex" with the name of the volume as
+plugin_instance.
+
+There will be type_instances "used" and "free" for the number of used and
+available bytes on the volume. If the volume has some space reserved for
+snapshots, a type_instance "snap_reserved" will be available. If the volume
+has SIS enabled, a type_instance "sis_saved" will be available. This is the
+number of bytes saved by the SIS feature.
+
+B<Note:> The current NetApp API has a bug that results in this value being
+reported as a 32E<nbsp>bit number. This plugin tries to guess the correct
+number which works most of the time. If you see strange values here, bug
+NetApp support to fix this.
+
+Repeat this option to specify multiple volumes.
+
+=item B<IgnoreSelectedCapacity> B<true>|B<false>
+
+Specify whether to collect only the volumes selected by the B<GetCapacity>
+option or to ignore those volumes. B<IgnoreSelectedCapacity> defaults to
+B<false>. However, if no B<GetCapacity> option is specified at all, all
+capacities will be selected anyway.
+
+=item B<GetSnapshot> I<VolumeName>
+
+Select volumes from which to collect snapshot information.
+
+Usually, the space used for snapshots is included in the space reported as
+"used". If snapshot information is collected as well, the space used for
+snapshots is subtracted from the used space.
+
+To make things even more interesting, it is possible to reserve space to be
+used for snapshots. If the space required for snapshots is less than that
+reserved space, there is "reserved free" and "reserved used" space in addition
+to "free" and "used". If the space required for snapshots exceeds the reserved
+space, that part allocated in the normal space is subtracted from the "used"
+space again.
+
+Repeat this option to specify multiple volumes.
+
+=item B<IgnoreSelectedSnapshot>
+
+Specify whether to collect only the volumes selected by the B<GetSnapshot>
+option or to ignore those volumes. B<IgnoreSelectedSnapshot> defaults to
+B<false>. However, if no B<GetSnapshot> option is specified at all, all
+capacities will be selected anyway.

=head2 Plugin C<netlink>
The C<netlink> plugin uses a netlink socket to query the Linux kernel about
1800 seconds, but setting this to 86400 seconds (one day) will not do much harm
either.
+=item B<ReportStats> B<true>|B<false>
+
+The network plugin cannot only receive and send statistics, it can also create
+statistics about itself. Collected data included the number of received and
+sent octets and packets, the length of the receive queue and the number of
+values handled. When set to B<true>, the I<Network plugin> will make these
+statistics available. Defaults to B<false>.
+
=back
=head2 Plugin C<nginx>
Specifies the location of the status file.
+=item B<Compression> B<true>|B<false>
+
+Sets whether or not statistics about the compression used by OpenVPN should be
+collected. This information is only available in I<single> mode. Enabled by
+default.
+
=back
=head2 Plugin C<oracle>
Sets the Time-To-Live of generated ICMP packets.
+=item B<SourceAddress> I<host>
+
+Sets the source address to use. I<host> may either be a numerical network
+address or a network hostname.
+
+=item B<Device> I<name>
+
+Sets the outgoing network device to be used. I<name> has to specify an
+interface name (e.E<nbsp>g. C<eth0>). This might not be supported by all
+operating systems.
+
=back
=head2 Plugin C<postgresql>

+=head2 Plugin C<python>
+
+This plugin embeds a Python-interpreter into collectd and provides an interface
+to collectd's plugin system. See L<collectd-python(5)> for its documentation.
+
+=head2 Plugin C<routeros>
+
+The C<routeros> plugin connects to a device running I<RouterOS>, the
+Linux-based operating system for routers by I<MikroTik>. The plugin uses
+I<librouteros> to connect and reads information about the interfaces and
+wireless connections of the device. The configuration supports querying
+multiple routers:
+
+ <Plugin "routeros">
+ <Router>
+ Host "router0.example.com"
+ User "collectd"
+ Password "secr3t"
+ CollectInterface true
+ </Router>
+ <Router>
+ Host "router1.example.com"
+ User "collectd"
+ Password "5ecret"
+ CollectInterface true
+ CollectRegistrationTable true
+ </Router>
+ </Plugin>
+
+As you can see above, the configuration of the I<routeros> plugin consists of
+one or more B<E<lt>RouterE<gt>> blocks. Within each block, the following
+options are understood:
+
+=over 4
+
+=item B<Host> I<Host>
+
+Hostname or IP-address of the router to connect to.
+
+=item B<Port> I<Port>
+
+Port name or port number used when connecting. If left unspecified, the default
+will be chosen by I<librouteros>, currently "8728". This option expects a
+string argument, even when a numeric port number is given.
+
+=item B<User> I<User>
+
+Use the user name I<User> to authenticate. Defaults to "admin".
+
+=item B<Password> I<Password>
+
+Set the password used to authenticate.
+
+=item B<CollectInterface> B<true>|B<false>
+
+When set to B<true>, interface statistics will be collected for all interfaces
+present on the device. Defaults to B<false>.
+
+=item B<CollectRegistrationTable> B<true>|B<false>
+
+When set to B<true>, information about wireless LAN connections will be
+collected. Defaults to B<false>.
+
+=back
+
=head2 Plugin C<rrdcached>
The C<rrdcached> plugin uses the RRDtool accelerator daemon, L<rrdcached(1)>,
usually), the graph will be empty (NAN) for a long time. People may not
understand why.
+=item B<hashed>
+
+Calculates a hash value of the host name and matches values according to that
+hash value. This makes it possible to divide all hosts into groups and match
+only values that are in a specific group. The intended use is in load
+balancing, where you want to handle only part of all data and leave the rest
+for other servers.
+
+The hashing function used tries to distribute the hosts evenly. First, it
+calculates a 32E<nbsp>bit hash value using the characters of the hostname:
+
+ hash_value = 0;
+ for (i = 0; host[i] != 0; i++)
+ hash_value = (hash_value * 251) + host[i];
+
+The constant 251 is a prime number which is supposed to make this hash value
+more random. The code then checks the group for this host according to the
+I<Total> and I<Match> arguments:
+
+ if ((hash_value % Total) == Match)
+ matches;
+ else
+ does not match;
+
+Please note that when you set I<Total> to two (i.E<nbsp>e. you have only two
+groups), then the least significant bit of the hash value will be the XOR of
+all least significant bits in the host name. One consequence is that when you
+have two hosts, "server0.example.com" and "server1.example.com", where the host
+name differs in one digit only and the digits differ by one, those hosts will
+never end up in the same group.
+
+Available options:
+
+=over 4
+
+=item B<Match> I<Match> I<Total>
+
+Divide the data into I<Total> groups and match all hosts in group I<Match> as
+described above. The groups are numbered from zero, i.E<nbsp>e. I<Match> must
+be smaller than I<Total>. I<Total> must be at least one, although only values
+greater than one really do make any sense.
+
+You can repeat this option to match multiple groups, for example:
+
+ Match 3 7
+ Match 5 7
+
+The above config will divide the data into seven groups and match groups three
+and five. One use would be to keep every value on two hosts so that if one
+fails the missing data can later be reconstructed from the second host.
+
+=back
+
+Example:
+
+ # Operate on the pre-cache chain, so that ignored values are not even in the
+ # global cache.
+ <Chain "PreCache">
+ <Rule>
+ <Match "hashed">
+ # Divide all received hosts in seven groups and accept all hosts in
+ # group three.
+ Match 3 7
+ </Match>
+ # If matched: Return and continue.
+ Target "return"
+ </Rule>
+ # If not matched: Return and stop.
+ Target "stop"
+ </Chain>
