What should I monitor with Nagios to tell if MS Exchange is up and running?

Hi,

I have Nagios up and running and I can monitor counters via Windows performance monitor in Nagios quite well. What I am looking for is the best counter that tells me reliable that MS Exchange 2003 is all fine up and running.

Is there one?

Best regards,

I would use the check_smtp  (port 25) plugin.
If the main exchange service fails, it would fail to properly accept SMTP sessions.


For more detailed checking, there is check_nt:

Or the Nagios Remote Plugin Executor:

You have the possibility of monitoring 'service running' state,  number of messages, queued.

And amount of traffic  (if network traffic greatly drops, then there may be something wrong, if it's a fairly active mail server)

Hi Mysidia,

thanks for your reply, reason why I am asking for some reliable check is that we recently expected our Exchange to pretend sending E-Mail to others but the mail was never delivered. Incoming mail was working fine...

I already set up some checks from that catch permon info, your NRPE links do basically the same, so I guess that's the way to go.
I think I will monitor number of messages queued and amount of traffic as you suggested.

Best regards,
