+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.

+Calculate and dispatch the configured percentile, i.e. compute the value, so

+latency.
+
+Metrics are reported with the I<type> B<Type> (the value of the above option)

+
+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
