UOC - OSSM Configuration

[Vector2]

we have been using Unified OSS Console 2.3 to view the network alarms both historical and real time alarms using two plugins OSSA and OSSM.

Few days ago, server VMs got rebooted. after that all services were down . i started them one by one and it went just fine ossa is working fine which is used for historical alarms. but OSSM is not working and it is not showing the real time alarms. it is throwing error "Appropriate Notification is missing in the workspace".

also previous saved filter which was created on production time are gone.

alarms are being fetched from UMB to H2 File Memory. and i could see the alarm count is changing  in that memory. but it is not showing in console.

any help would be appreciated.

Regards
