+Since it's C<mod_status> module is very similar to Apache's, B<lighttpd> is
+also supported. It introduces a new field, called C<BusyServers>, to count the
+number of currently connected clients. This field is also supported.
+
The following options are accepted by the C<apache>-plugin:
=over 4
=back
+=head2 Plugin C<csv>
+
+=over 4
+
+=item B<DataDir> I<Directory>
+
+Set the directory to store RRD-files under. Per default RRD-files are generated
+beneath the daemon's working directory, i.E<nbsp>e. the B<BaseDir>.
+
+=back

=head2 Plugin C<df>
=over 4
=head2 Plugin C<rrdtool>
+You can use the settings B<StepSize>, B<HeartBeat>, B<RRARows>, and B<XFF> to
+finetune your RRD-files. Please read L<rrdcreate(1)> if you encounter problems
+using these settings. If you don't want to dive into the depths of RRDTool, you
+can savely ignore these settings.
+
=over 4
+=item B<DataDir> I<Directory>
+
+Set the directory to store CSV-files under. Per default CSV-files are generated
+beneath the daemon's working directory, i.E<nbsp>e. the B<BaseDir>.
+
+=item B<StepSize> I<Seconds>
+
+Sets the stepsize of newly created RRD-files. Ideally (and per default) this
+setting is identical to the global B<Interval>-option and should not be
+smaller. If unsure, don't set this option.
+
+=item B<HeartBeat> I<Seconds>
+
+Sets the heartbeat of newly created RRD-files. Ideally (and per default) this
+setting is bigger than the B<Interval>-setting. If unsure, don't set this
+option.
+
+=item B<RRARows> I<NumRows>
+
+The C<rrdtool plugin> calculates the number of PDPs per CDP based on the
+B<StepSize>, this setting and a timespan. This plugin creates RRD-files with
+three times five RRAs, i. e. five RRAs with the CFs B<MIN>, B<AVERAGE>, and
+B<MAX>. The five RRAs are optimized for graphs covering one hour, one day, one
+week, one month, and one year.
+
+So for each timespan, it calculates how many PDPs need to be consolidated into
+one CDP by calculating:
+ number of PDPs = timespan / (stepsize * rrarows)
+
+Bottom line is, set this no smaller than the width of you graphs in pixels.
+
+=item B<XFF> I<Factor>
+
+Set the "XFiles Factor". This is mostly interesting if you set B<StepSize>
+bigger than B<Interval>. If unsure, don't set this option.
+
=item B<CacheFlush> I<Seconds>
When the C<rrdtool plugin> uses a cache (by setting B<CacheTimeout>, see below)
The tradeoff is that the graphs kind of "drag behind" and that more memory is
used.
-=item B<DataDir> I<Directory>
-
-Set the directory to store RRD-files under. Per default RRD-files are generated
-beneath the daemon's working directory, i.E<nbsp>e. the B<BaseDir>.
