[Orca-users] RE: What is the best way to create classes of server s?

Ahh.  I understand now.  On a related topic ...

Now I see a section in the orcallator.cfg called "group group_name {}" where
I can apparently define files other
than those generated by orcallator to be examined by orca for graphing.  Am
I correct to assume that if I create
custom groups and if the files do not exist for a particular machine then
empty plots will not be created in the 
daily, weekly, monthly, etc subsections for that machine?  If not, is there
a method necessary to create excludes
based on machines or will I have to have a separate orca process to handle
the custom files?

Thanks again for your patience and time!  I am starting to generate some
really nice graphs!

No, all of the tests are for defined, not for 0 versus 1.

In your case, you'll need to modify start_orcallator and remove the
-DWATCH_OS from the line

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

because orcallator.se defines WATCH_NFS_CLIENT and WATCH_NFS_SERVER when
WATCH_OS is defined.

Then you'll need to add all of the other -DWATCH_**** that you want to watch
to start_orcallator.se.
