I have a multi Tenancy Environment of UIM, the issue I face here is that nodes even after putting in maintenance mode are sending alerts. I want to check where are the logs which can state that my node was in maintenance mode from this to this time.
Increase the log level of nas to 3 and check log during the alert generated time. You can see below log for every alert with the maintenance state
nas: maint: dev_id 'D9772EFD29B0DDB67FF7252C72E3772AB' from 'subscriber' '10.50.208.48' is NOT in maintenance.
There is a known behavior in the past at maintenance_mode probe send a false alarm.
So need to check your current maintenance_mode probe version if is at least at 8.20 version.
For more details I recommend you to open a CA Support ticket!
If you have remote nas probes you need on those remote nas an extra key:
maintenance_mode_address = /domain/hubname/hubrobot/maintenance_mode
