We do have at least one customer who has built the integration with System Pulse based in the Northeast. I don't they did it through SNMP however. SystemPulse has a SOAP based API that can be leveraged for workflow response times and exceptions. We're looking at tying this directly into an event on the ServiceNow side, but we're still early on from a spoke/integration standpoint. It would be too hard to build on your own give the API.
Reach out with any questions and I'll update any progress here.
