+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

+=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.

+=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.

+=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
