I read through the Distributed Monitoring Document in the following link: <a target="_blank" href="http://nagios.sourceforge.net/docs/2_0/distributed.html">http://nagios.sourceforge.net/docs/2_0/distributed.html</a> In the last section "Performing Host Checks", It mentions ochp command can be used for processing host check. Can I use check_by_ssh in the ochp command? The reason of using check_by_ssh is that my clients don't want to have an *Agent* installed in their server. If I can use check_by_ssh with ochp, my goal is accomplished.

If you haven't guessed, what you're trying to accomplish isn't clear. The question, as you've put it, doesn't make sense. About the only case I can think of that you might need to use NSCA and check_by_ssh together were if you were checking a third host that was only accessible from a second host, neither of which are directly accessible by your nagios server (i.e. firewalled, or other). send_nsca can be run on a remote host to send check results executed by an external program (nagios on that remote host or your own script), back to another nagios machine running NSCA. This is a passive check for nagios. Nagios doesn't 'call' or 'run' nsca or send_nsca. The Distributed Monitoring documentation, while specific to running a distributed nagios instance, talks about how this is accomplished. check_by_ssh is a plugin that is actively run by your nagios machine that will ssh into a remote host, execute a nagios plugin installed there and return the results to nagios as an active check. If you have direct access to the monitored machine and don't mind setting up key-based authentication for this purpose, this is probably the easiest way to go. Another option might be NRPE. Both accomplish the pretty much the same thing, just in very different ways. -- Marc ------------------------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
