I have installed CUOM 2.3 and added my Publisher as a Device.
The first alarm I receive is "Unknown Publisher".
Description: The publisher in the cluster is unknown to Operations Manager. This event is generated based on polling RTMT precanned counters. Trigger: RTMT.
Device Type: Unified CM.
Recommended Action: Check if the Publisher is managed by Operations Manager.
But the server I have added is the publisher.
Have you got any idea why this happens?
