Do not set this more than the B<-w> value divided by your average RRD step
size.

The B<update> command can send values to the daemon instead of writing them to
updates have already been applied. It is I<only> valid in the journal; it
is not accepted from the other command channels.
+=item B<FIRST> I<filename> [I<rranum>]
+
+Return the timestamp for the first CDP in the specified RRA. Default is to
+use RRA zero if none is specified.
+
+=item B<LAST> I<filename>
+
+Return the timestamp for the last update to the specified RRD. Note that the
+cache is I<not> flushed before checking, as the client is expected to request
+this separately if it is required.
+
+=item B<INFO> I<filename>
+
+Return the configuration information for the specified RRD. Note that the
+cache is I<not> flushed before checking, as the client is expected to request
+this separately if it is required.
+
+The information is returned, one item per line, with the format:
+
+ I<keyname> I<type> I<value>
+
+=item B<CREATE> I<filename> [-s I<stepsize>] [-b I<begintime>] [-O] I<DSdefinitions> ... I<RRAdefinitions> ...
+
+This will create the RRD file according to the supplied parameters, provided
+the parameters are valid, and (if the -O option is given or if the rrdcached
+was started with the -O flag) the specified I<filename> does not already
+exist.
