B<LoadPlugin> statement. B<LoadPlugin> statements are still required for
plugins that don't provide any configuration, e.g. the I<Load plugin>.
+=item B<CollectInternalStats> B<false>|B<true>
+
+When set to B<true>, various statistics about the I<collectd> daemon will be
+collected, with "collectd" as the I<plugin name>. Defaults to B<false>.
+
+The "write_queue" I<plugin instance> reports the number of elements currently
+queued and the number of elements dropped off the queue by the
+B<WriteQueueLimitLow>/B<WriteQueueLimitHigh> mechanism.
+
+The "cache" I<plugin instance> reports the number of elements in the value list
+cache (the cache you can interact with using L<collectd-unixsock(5)>).
+
=item B<Include> I<Path> [I<pattern>]
If I<Path> points to a file, includes that file. If I<Path> points to a
unset, the latter will default to half of B<WriteQueueLimitHigh>.
If you do not want to randomly drop values when the queue size is between
-I<LowNum> and I<HighNum>, set If B<WriteQueueLimitHigh> and
-B<WriteQueueLimitLow> to same value.
+I<LowNum> and I<HighNum>, set B<WriteQueueLimitHigh> and B<WriteQueueLimitLow>
+to the same value.
+
+Enabling the B<CollectInternalStats> option is of great help to figure out the
+values to set B<WriteQueueLimitHigh> and B<WriteQueueLimitLow> to.

+=head2 Plugin C<battery>
+
+The I<battery plugin> reports the remaining capacity, power and voltage of
+laptop batteries.
+
+=over 4
+
+=item B<ValuesPercentage> B<false>|B<true>
+
+When enabled, remaining capacity is reported as a percentage, e.g. "42%
+capacity remaining". Otherwise the capacity is stored as reported by the
+battery, most likely in "Wh". This option does not work with all input methods,
+in particular when only C</proc/pmu> is available on an old Linux system.
+Defaults to B<false>.
+
+=item B<ReportDegraded> B<false>|B<true>
+
+Typical laptop batteries degrade over time, meaning the capacity decreases with
+recharge cycles. The maximum charge of the previous charge cycle is tracked as
+"last full capacity" and used to determine that a battery is "fully charged".
+
+When this option is set to B<false>, the default, the I<battery plugin> will
+only report the remaining capacity. If the B<ValuesPercentage> option is
+enabled, the relative remaining capacity is calculated as the ratio of the
+"remaining capacity" and the "last full capacity". This is what most tools,
+such as the status bar of desktop environments, also do.
+
+When set to B<true>, the battery plugin will report three values: B<charged>
+(remaining capacity), B<discharged> (difference between "last full capacity"
+and "remaining capacity") and B<degraded> (difference between "design capacity"
+and "last full capacity").

=head2 Plugin C<bind>
Starting with BIND 9.5.0, the most widely used DNS server software provides
that the manual selection of an interface for unicast traffic is only
necessary in rare cases.
+=item B<ResolveInterval> I<Seconds>
+
+Sets the interval at which to re-resolve the DNS for the I<Host>. This is
+useful to force a regular DNS lookup to support a high availability setup. If
+not specified, re-resolves are never attempted.
