Getting events from SIM DB with SiteScope DB Technology Integration monitor seems to be the easiest way. It proved to work many times in the past. An alternative may be SNMP Traps that SIM sends to SiteScope and SNMP Trap Technology Integration monitor processes the traps.
This integration is not productized, so no official documentation exists. HP Software Professional Services have some unofficial docs created by consultants who implemented the integration at customers sites. But apparently those docs are not supposed to be shared on a public forum.
Hmmm... since we did our whole install with Prof. services I wonder if they would give us the document. Integrating SIM was out of scope for their visit however now that we've been running for a bit we are realizing we need these SIM events on our console.
