OWA current user monitoring

Question

Can Orion NPM easily monitor the current number of users accessing an OWA server?  Our OWA is accesible from the internet using an MS ISA server providing a reverse proxy in the DMZ, back to the internal OWA servers.  Is there a custom MIB that I can use to monitor/log the amount of concurrent/active/live connections to our OWA systems, either through ISA, IIS, or the Exchange services?  We have recently been snowbound and upper management would like to see remote user stats.  I have been monitoring active VPN connections through out ASA, but OWA eludes us.

BTW, we do not own APM, and the procurement process would put that months out.

Thanks!

While you get APM in house, you could use the free WMI tool here to pull the Exchange counter

We don't have any current plans for APM at this time.  That's why I was asking if there was any other way?

Simple Network Management Protocol (SNMP) support of industry standard MADMAN MIB allows an entire Exchange enterprise to be monitored remotely

I think this could give you some vision into what's going on with OWA
