+=head2 Plugin C<statsd>
+
+The I<statsd plugin> listens to a UDP socket, reads "events" in the statsd
+protocol and dispatches rates or other aggregates of these numbers
+periodically.
+
+The plugin implements the I<Counter>, I<Timer>, I<Gauge> and I<Set> types which
+are dispatched as the I<collectd> types C<derive>, C<latency>, C<gauge> and
+C<objects> respectively.
+
+The following configuration options are valid:

+These options control what happens if metrics are not updated in an interval.
+If set to B<False>, the default, metrics are dispatched unchanged, i.e. the
+rate of counters and size of sets will be zero, timers report C<NaN> and gauges
+are unchanged. If set to B<True>, the such metrics are not dispatched and
+removed from the internal cache.
+
+=item B<TimerPercentile> I<Percent>
+
+Calculate and dispatch the configured percentile, i.e. compute the latency, so
+that I<Percent> of all reported timers are smaller than or equal to the
+computed latency. This is useful for cutting off the long tail latency, as it's
+often done in I<Service Level Agreements> (SLAs).
