[Orca-users] newbie questions about monitoring multiple hosts...

[Steve Gilbert]

I'm a new Orca user (thanks for such a great tool, Blair...
this is really going to make my life easier), and thus far
I've just been using it to monitor one machine to test it
out.  Now I need to get it in production and monitor some
web servers that reside outside our firewall.  I've read
all the documentation on the web and looked through the
archives of this list.  I have a couple of (hopefully)
simple questions just to make sure I understand how all
the parts fit together.

First, in case it matters...
Solaris 2.6 (all SPARC platforms)
SE 3.1
Orca 0.26
orcallator.se 1.25
orcallator.cfg 1.25

My plan is to run the orcallator on the target systems, and
then use a perl script that calls rsync to pull the data files
back inside our firewall to a central collector host which will
run Orca, etc.

1. With this model, do I even need to install Orca at all on the
   target machines?  It seems that I should just be able to install
   SE and run orcallator.se on them.  If this is the case, where
   will my data files be written?  Under the prefix directory that
   is specified in /etc/rc3.d/S99orcallator?

2. The data files that orcallator.se generates are only the percol-*
   files, right?  The RRD files are only used by the orca script that
   runs on the collector machine?

3. By the same token, the orcallator.cfg file is also only used by
   orca on the collector?  The target machiens should have no use
   for that file?

...thanks for helping me put all this together.  I hope my questions
aren't too silly.  Did a FAQ for all this stuff ever get created?
