+fresh data even if the daemon is configured to cache values for a long time.
+For a list of accepted formats, see the B<-l> option in the L<rrdcached> manual.

+=item B<--noflush>
+
+Omit the C<flush> command usually sent to the daemon prior to retrieving the
+data. If all you are interested in the the RRD Structure, and not the last update
