+The I<gmond> plugin received the multicast traffic sent by B<gmond>, the
+statistics collection daemon of Ganglia. Mappings for the standard "metrics"
+are built-in, custom mappings may be added via B<Metric> blocks, see below.

+Synopsis:

=head2 Plugin C<ping>
+The I<Ping> plugin starts a new thread which sends ICMP "ping" packets to the
+configured hosts periodically and measures the network latency. Whenever the
+C<read> function of the plugin is called, it submits the average latency, the
+standard deviation and the drop rate for each host.
+
+Available configuration options:
+
=over 4
=item B<Host> I<IP-address>
Host to ping periodically. This option may be repeated several times to ping
multiple hosts.
+=item B<Interval> I<Seconds>
+
+Sets the interval in which to send ICMP echo packets to the configured hosts.
+This is B<not> the interval in which statistics are queries from the plugin but
+the interval in which the hosts are "pinged". Therefore, the setting here
+should be smaller than or equal to the global B<Interval> setting. Fractional
+times, such as "1.24" are allowed.
+
+Default: B<1.0>
+
+=item B<Timeout> I<Seconds>
+
+Time to wait for a response from the host to which an ICMP packet had been
+sent. If a reply was not received after I<Seconds> seconds, the host is assumed
+to be down or the packet to be dropped. This setting must be smaller than the
+B<Interval> setting above for the plugin to work correctly. Fractional
+arguments are accepted.
+
+Default: B<0.9>
+
=item B<TTL> I<0-255>
Sets the Time-To-Live of generated ICMP packets.
=back
+=head2 Plugin C<protocols>
+
+Collects a lot of information about various network protocols, such as I<IP>,
+I<TCP>, I<UDP>, etc.
+
+Available configuration options:
+
+=over 4
+
+=item B<Value> I<Selector>
+
+Selects whether or not to select a specific value. The string being matched is
+of the form "I<Protocol>:I<ValueName>", where I<Protocol> will be used as the
+plugin instance and I<ValueName> will be used as type instance. An example of
+the string being used would be C<Tcp:RetransSegs>.
+
+You can use regular expressions to match a large number of values with just one
+configuration option. To select all "extended" I<TCP> values, you could use the
+following statement:
+
+ Value "/^TcpExt:/"
+
+Whether only matched values are selected or all matched values are ignored
+depends on the B<IgnoreSelected>. By default, only matched values are selected.
+If no value is configured at all, all values will be selected.
+
+=item B<IgnoreSelected> B<true>|B<false>
+
+If set to B<true>, inverts the selection made by B<Value>, i.E<nbsp>e. all
+matching values will be ignored.
