On my machines, I use the following boottime script
(/etc/rc2.d/S99orcallator).  As you showed see, this runs both Orca
components as a non-root user.  If you are running it as root, you should
remove the "su -" stuff.  On the non-graphing machines, I specifically
delete orcallator.cfg so that the graphing engine doesn't start.  I collect
data at regular intervals using rsync over ssh.

Not sure what you mean about file rotation and a monthly graph.  Monthly
graphs are part of what Orca generates by default.  If you mean you want to
retain a copy of a specific graph at regular intervals, that's just a
crontab job and a cp command.  No rocket science there.
