+=item B<Distribution>
+
+Type to do calculations based on the distribution of values, primarily
+calculating percentiles. This is primarily geared towards latency, but can be
+used for other metrics as well. The range of values tracked with this setting
+must be in the range (0–2^34) and can be fractional. Please note that neither
+zero nor 2^34 are inclusive bounds, i.e. zero I<cannot> be handled by a
+distribution.
+
+This option must be used together with the B<Percentile> and/or B<Bucket>
+options.

+=item B<Percentile> I<Percent>
+
+Calculate and dispatch the configured percentile, i.e. compute the value, so
+that I<Percent> of all matched values are smaller than or equal to the computed
+latency.
+
+Metrics are reported with the I<type> B<Type> (the value of the above option)
+and the I<type instance> C<[E<lt>InstanceE<gt>-]E<lt>PercentE<gt>>.
+
+This option may be repeated to calculate more than one percentile.
+
+=item B<Bucket> I<lower_bound> I<upper_bound>
+
+Export the number of values (a C<DERIVE>) falling within the given range. Both,
+I<lower_bound> and I<upper_bound> may be a fractional number, such as B<0.5>.
+Each B<Bucket> option specifies an interval C<(I<lower_bound>,
+I<upper_bound>]>, i.e. the range I<excludes> the lower bound and I<includes>
+the upper bound. I<lower_bound> and I<upper_bound> may be zero, meaning no
+lower/upper bound.
+
+To export the entire (0–inf) range without overlap, use the upper bound of the
+previous range as the lower bound of the following range. In other words, use
+the following schema:
+
+ Bucket 0 1
+ Bucket 1 2
+ Bucket 2 5
+ Bucket 5 10
+ Bucket 10 20
+ Bucket 20 50
+ Bucket 50 0
+
+Metrics are reported with the I<type> C<bucket> and the I<type instance>
+C<E<lt>TypeE<gt>[-E<lt>InstanceE<gt>]-E<lt>lower_boundE<gt>_E<lt>upper_boundE<gt>>.
+
+This option may be repeated to calculate more than one rate.

-As you'd expect the B<Gauge*> types interpret the submatch as a floating point
-number, using L<strtod(3)>. The B<Counter*> and B<AbsoluteSet> types interpret
-the submatch as an unsigned integer using L<strtoull(3)>. The B<Derive*> types
-interpret the submatch as a signed integer using L<strtoll(3)>. B<CounterInc>
-and B<DeriveInc> do not use the submatch at all and it may be omitted in this
-case.
