-=head1 NAME
-
-collectd-flush - Small command line utility to flush collectd
-
-=head1 SYNOPSIS
-
-collectd-flush I<[options]>
-
-=head1 DESCRIPTION
-
-This small command line utitilty uses C<libcollectdclient> to flush collectd
-through a socket from the L<unixsock plugin>. Useful if you want to be sure
-you have the latest values in your RRD files before graphing them or copying
-them somewhere else.
-
-=head1 ARGUMENTS AND OPTIONS
-
-The following arguments and options are understood by collectd-flush. The order
-of the arguments generally doesn't matter, as long as no argument is passed
-more than once.
-
-=over 4
-
-=item B<-h>, B<--help>
-
-Display information about the options.
-
-=item B<-s>, B<--socket=>I<socket>
-
-Path to the UNIX socket opened by collectd's C<unixsock plugin>.
-Default: /var/run/collectd-unixsock
-
-=item B<-p>, B<--plugin=>I<plugin>
-
-Plugin to flush I<to>. Example: B<rrdtool>.
-
-=item B<-i>, B<--identifier=>I<identifier>
-
-If this option is present, only the data specified by I<identifier> will be flushed.
-I<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 hostname if omitted. No error is returned if the
-specified identifier does not exist (this is a limitation in the
-C<libcollectdclient> library).You can only specify one identifier each time you
-run this program (even though L<collectd-unixsock(5)> supports multiple
-identifiers).
-
-=item B<-t>, B<--timeout=>I<timeout>
-
-Only flush values older than I<timeout>.

=head1 SYNOPSIS

+ Globals true
+ </LoadPlugin>
# ...
<Plugin perl>
IncludeDir "/path/to/perl/plugins"
Perl-script every time you want to read a value with the C<exec plugin> (see
L<collectd-exec(5)>) and provides a lot more functionality, too.
+When loading the C<perl plugin>, the B<Globals> option should be enabled.
+Else, the perl plugin will fail to load any Perl modules implemented in C,
+which includes, amongst many others, the B<threads> module used by the plugin
+itself. See the documentation of the B<Globals> option in L<collectd.conf(5)>
+for details.

type, data-set and value-list is passed to all write-callbacks that are
registered with the daemon.
-B<Note>: Prior to version 4.4 of collectd, the data-set type used to be passed

+available for resolving unresolved symbols in subsequently loaded plugins if
+that is supported by your system. By default, this is disabled.
+
+This is useful (or possibly even required), e.E<nbsp>g., when loading a plugin
+that embeds some scripting language into the daemon (e.E<nbsp>g. the C<perl>
+or C<python> plugins). Scripting languages usually provide means to load
+extensions written in C. Those extensions require symbols provided by the
+interpreter, which is loaded as a dependency of the respective collectd
+plugin. See the documentation of those plugins (e.E<nbsp>g.,
+L<collectd-perl(5)> or L<collectd-python(5)>) for details.

-The following options are accepted by the C<apache>-plugin:
+The configuration of the I<Apache> plugin consists of one or more
+C<E<lt>InstanceE<nbsp>/E<gt>> blocks. Each block requires one string argument
+as the instance name. For example:

+
+The instance name will be used as the I<plugin instance>. To emulate the old
+(versionE<nbsp>4) behavior, you can use an empty string (""). In order for the
+plugin to work correctly, each instance name must be unique. This is not
+enforced by the plugin and it is your responsibility to ensure it.

- ValuesFrom I<name of the x. column>

+=head2 Plugin C<redis>
+
+The I<Redis plugin> connects to one or more Redis servers and gathers
+information about each server's state. For each server there is a I<Node> block
+which configures the connection parameters for this node.
+
+ <Plugin redis>
+ <Node "example">
+ Host "localhost"
+ Port "6379"
+ Timeout 2000
+ </Node>
+ </Plugin>
+
+The information shown in the synopsis above is the I<default configuration>
+which is used by the plugin if no configuration is present.
+
+=over 4
+
+=item B<Node> I<Nodename>
+
+The B<Node> block identifies a new Redis node, that is a new Redis instance
+running in an specified host and port. The name for node is a canonical
+identifier which is used as I<plugin instance>. It is limited to
+64E<nbsp>characters in length.
+
+=item B<Host> I<Hostname>
+
+The B<Host> option is the hostname or IP-address where the Redis instance is
+running on.
+
+=item B<Port> I<Port>
+
+The B<Port> option is the TCP port on which the Redis instance accepts
+connections. Either a service name of a port number may be given. Please note
+that numerical port numbers must be given as a string, too.
+
+=item B<Timeout> I<Timeout in miliseconds>
+
+The B<Timeout> option set the socket timeout for node response. Since the Redis
+read function is blocking, you should keep this value as low as possible. Keep
+in mind that the sum of all B<Timeout> values for all B<Nodes> should be lower
+than B<Interval> defined globally.

The C<rrdcached> plugin uses the RRDtool accelerator daemon, L<rrdcached(1)>,

=item B<CounterAdd>
-Add the matched value to the internal counter.
+=item B<DeriveAdd>
+
+Add the matched value to the internal counter. In case of B<DeriveAdd>, the
+matched number may be negative, which will effectively subtract from the
+internal counter.
=item B<CounterInc>

+=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.
