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

+
+The B<Server> statement sets the server to send datagrams B<to>. The statement
+may occur multiple times to send each datagram to multiple destinations.
+
+The B<Listen> statement sets the interfaces to bind to. When multiple
+statements are found the daemon will bind to multiple interfaces.
+
+The argument I<Host> may be a hostname, an IPv4 address or an IPv6 address. If
+the argument is a multicast address the daemon will join that multicast group.
+
+If no B<Listen> statement is found the server tries join both, the default IPv6
+multicast group and the default IPv4 multicast group. If no B<Server> statement
+is found the client will try to send data to the IPv6 multicast group first. If
+that failes the client will try the IPv4 multicast group.
+
+The default IPv6 multicast group is C<ff18::efc0:4a42>. The default IPv4
+multicast group is C<239.192.74.66>.
+
+The optional I<Port> argument sets the port to use. It can either be given
+using a numeric port number or a service name. If the argument is omited the
+default port B<25826> is assumed.
+
+=item B<TimeToLive> I<1-255>
+
+Set the time-to-live of sent packets. This applies to all, unicast and
+multicast, and IPv4 and IPv6 packets. The default is to not change this value.
+That means that multicast packets will be sent with a TTL of C<1> (one) on most
+operating systems.

+
+You can use the settings B<StepSize>, B<HeartBeat>, B<RRARows>, and B<XFF> to
+finetune your RRD-files. Please read L<rrdcreate(1)> if you encounter problems
+using these settings. If you don't want to dive into the depths of RRDTool, you
+can savely ignore these settings.
+
+=over 4
+
+=item B<DataDir> I<Directory>
+
+Set the directory to store CSV-files under. Per default CSV-files are generated
+beneath the daemon's working directory, i.E<nbsp>e. the B<BaseDir>.
+
+=item B<StepSize> I<Seconds>
+
+Sets the stepsize of newly created RRD-files. Ideally (and per default) this
+setting is identical to the global B<Interval>-option and should not be
+smaller. If unsure, don't set this option.
+
+=item B<HeartBeat> I<Seconds>
+
+Sets the heartbeat of newly created RRD-files. Ideally (and per default) this
+setting is bigger than the B<Interval>-setting. If unsure, don't set this
+option.
+
+=item B<RRARows> I<NumRows>
+
+The C<rrdtool plugin> calculates the number of PDPs per CDP based on the
+B<StepSize>, this setting and a timespan. This plugin creates RRD-files with
+three times five RRAs, i. e. five RRAs with the CFs B<MIN>, B<AVERAGE>, and
+B<MAX>. The five RRAs are optimized for graphs covering one hour, one day, one
+week, one month, and one year.
+
+So for each timespan, it calculates how many PDPs need to be consolidated into
+one CDP by calculating:
+ number of PDPs = timespan / (stepsize * rrarows)
+
+Bottom line is, set this no smaller than the width of you graphs in pixels.
+
+=item B<XFF> I<Factor>
+
+Set the "XFiles Factor". This is mostly interesting if you set B<StepSize>
+bigger than B<Interval>. If unsure, don't set this option.
+
+=item B<CacheFlush> I<Seconds>
+
+When the C<rrdtool plugin> uses a cache (by setting B<CacheTimeout>, see below)
+it writes all values for a certain RRD-file if the oldest value is older than
+(or equal to) the number of seconds specified. If some RRD-file is not updated
+anymore for some reason (the computer was shut down, the network is broken,
+etc.) some values may still be in the cache. If B<CacheFlush> is set, then the
+entire cache is searched for entries older than B<CacheTimeout> seconds and
+written to disk every I<Seconds> seconds. Since this is kind of expensive and
+does nothing under normal circumstances, this value should not be too small.
+900 seconds might be a good value, though setting this to 7200 seconds doesn't
+normally do much harm either.
+
+=item B<CacheTimeout> I<Seconds>
+
+If this option is set to a value greater than zero, the C<rrdtool plugin> will
+save values in a cache, as described above. Writing multiple values at once
+reduces IO-operations and thus lessens the load produced by updating the files.
+The tradeoff is that the graphs kind of "drag behind" and that more memory is
+used.

=over 4
-=item B<ExtendedSensorNaming> I<true>|I<false>
-
-If set to I<true> this option switches on the extended sensors and RRD-files
-naming. This option exists to preserve backwards compatibility. It is
-recommended that you set this option to I<true>. The default is I<false> to
-maintain compatibility only.
-
-Sensors get names like I<chip-bus-address/type-feature> (e.g.
-I<it8712-isa-0290/voltage-in1>) and RRD files are therefore stored in a
-standalone directory inside the B<DataDir> directory and get names like
-I<lm_sensors-chip-bus-address/type-feature.rrd> (e.g.
-I<lm_sensors-it8712-isa-0290/voltage-in1.rrd>).
-
-The B<ExtendedSensorNaming> option breaks the compatibility with previous
-sensors and RRD files naming and the place where RRDs are stored. If you turn
-it on, the plugin will create new RRD files in a standalone directory inside
-the B<DataDir> directory and without previous history. You can rename ``old''
-RRD-files to preserve already collected statistics, because the file layout
-hasn't changed. If you have two chips of the same type, you need to use
-B<ExtendedSensorNaming> in order to collect information from both chips.
-
-If not set or set to I<false>, the extended naming is not active. Sensors get
-names like I<chip-feature> (e.g. I<it8712-in1>) and RRD files are stored in the
-main B<DataDir> directory and get names like I<sensors-chip-feature.rrd> (e.g.
-I<sensors-it8712-in1.rrd>). You simply continue using the plugin the old way
-and additionally also getting data for newly added sensors in this mode.
-
-=item B<Sensor> I<chip-feature> or B<Sensor> I<chip-bus-address/type-feature>
-
-Both option modes select the name of the sensor which you want to collect.
-The naming scheme is dependent on the state of the B<ExtendedSensorNaming>
-option (see previous option). Both option modes can also deselect the
-sensor according to the B<IgnoreSelected> option (see below).
-
-For example the option "B<Sensor> I<it8712-in1>" will cause the collectd
-to gather data for the voltage sensor I<in1> of the I<it8712> chip in case
-of the B<ExtendedSensorNaming> option is set to I<false>.
-
-And likewise the option "B<Sensor> I<it8712-isa-0290/voltage-in1>" will
-cause the collectd to gather data for the voltage sensor I<in1> of the I<it8712>
-on the isa bus at the address 0290 in case of the B<ExtendedSensorNaming>
-option set to I<true>.
+=item B<Sensor> I<chip-bus-address/type-feature>
-=item B<IgnoreSelected> I<true>|I<false>
+Selects the name of the sensor which you want to collect or ignore, depending
+on the B<IgnoreSelected> below. For example, the option "B<Sensor>
+I<it8712-isa-0290/voltage-in1>" will cause collectd to gather data for the
+voltage sensor I<in1> of the I<it8712> on the isa bus at the address 0290.
-If no configuration if given, the B<sensors>-plugin will collect data from
-all sensors. This may not be practical, especially for uninteresting sensors.
-Thus, you can use the B<Sensor>-option to pick the sensors you're
-interested in. Sometimes, however, it's easier/prefered to collect all
-sensors I<except> a few ones. This option enables you to
-do that: By setting B<IgnoreSelected> to I<true> the effect of
-B<Sensor> is inversed: All selected sensors are ignored and all
-other sensors are collected.
