Issue:

We're not able to see the spectrum alarms in Infrastructure Manager but we can see them in the UMP alarm console.

Environment:
UIM 8.51 with Spectrum integration
Cause:

Infrastructure Manager populates the alarm window in two ways:

1) By creating a temporary queue on the hub and listening to in-bound alarms live.

2) By reading the database.db and transactionlog.db files in the NAS directory.

When the alarm is generated in Spectrum the spectrumgtw will send the the alarm to the EMS probe rather than NAS. Infrastructure Manager will not be able to pull spectrumgtw alarm information after it leaves the temporary queue because it is not being stored in the database.db and transactionlog.db files. Once the Infrastructure Manager alarm console is refreshed, the alarm will disappear. 

 

Resolution:

This is expected behavior due to the limitations in Infrastructure Manager. Soon as Infrastructure Manager's alarm console updates the alarm will disappear.

UMP does not have this limitation as the UMP checks alarm's in both the NAS_ alarm tables and via callbacks to EMS.
