No one has any ideas?
Have you try using the Windows eventlog to send SNMP syslogs or traps to your Orion Server & alert that way?I use Snare to send syslogs when any System eventlog with 'Solarwinds' is recorded to tell me when a service has stopped or started on my server.If there is a specific eventlog entry that indicates when a server is hung, you could alert on that (if you can catch it before it is completely fubarred).
What about using Orion to monitor volumes or interfaces on a server and alerting when the volume/interface is not UP (or is Unknown)?
If you only would have said that last week. I ended up watching the loop Back address on the servers for the status of unknow. Using the loop Back fixed the issue of nodes with two or more NIC's.
Just glad to hear that you found a solution that works for you!
