We've integrated UIM 8.1 with Spectrum 9.4.1.
Events are getting through, but alert mapping is almost non-existent. Lots of UIM alerts are mapped to the same event id and get the same alert (ex 0x6330002), while they are different alerts.
Also lots of UIM alerts get the 0x10801 event, Unknown alert. This is almost unworkable as we'll need to manually map the events to the correct alerts or even create new ones.
It would be most useful if there's a decent event handling and alert mapping available in Spectrum for UIM.
