Symptom:

In SCOM 2012, we cannot discover windows computers as network devices, so the SNMP trap send from Windows computers can be received by SCOM management server.

Analysis:

After discussing with the owner of network monitoring in Operations Manager product group, I personally confirmed it’s not possible to monitor SNMP traps from a windows computer via SNMP monitors.

I also learnt that the reason to filter the windows computers out of network discovery is because after we introduced network monitoring in OM 2012, a device is either a network device or a computer, if we support SNMP on a Windows computer, the same device will be discovered twice, once as a Windows computer, once as a network device and this will cause problem.

So in this scenario, we will need to use other mechanism to receive the trap and generate alert.

Alternate Way:

1.       Customize the application to send alert via other method like eventlog.

2.       Use other solution to receive the trap and call SCOM API to generate a property bag, and SCOM can receive this and generate alert.
