1) You'll need to modify the beginning of the file lib/Orca/Constants.pm.
   The variables to modify are: @RRA_PLOT_TYPES, @RRA_PDP_COUNTS,
   @RRA_ROW_COUNTS, @CONST_IMAGE_PLOT_TYPES and %CONST_IMAGE_PLOT_INFO.
   I would really read the RRD manual page to see how RRD works.

2) Edit orcallator.cfg to change the interval here.

3) Finally, you'll need to edit start_orcallator and change

   nohup $SE $SE_PATCHES -DWATCH_OS $WATCH_WEB $libdir/orcallator.se &

   to

   nohup $SE $SE_PATCHES -DWATCH_OS $WATCH_WEB $libdir/orcallator.se XXX &

   where XXX is your new measurement interval.

4) After you make these changes, you'll need to stop Orca, delete all of
   the RRD files, and restart Orca.

The graphs are updated every 5 minutes if you leave Orca running
continously.  Running Orca from cron obvious updates the graphs as often
as Orca is run.

Best,
