How do I view current and previous alarms?

The merged alarm list displays all active and previously-active alarms in the network (or for specific NEs) over a specified time period.

Perform the following operations to manage the order and content of your alarm list:

Filter the Merged Alarm List. Click on the Source and Time Period chip filters to display alarm messages from a specific source system, and over a specific time period.
Filter the alarm list under a specific column using a quick filter. Choose an operator and enter a value in the search field at the top of a column and press Enter, or use the date picker or drop-down list (where available) and press Enter.
Sort the alarm list under a specific column. Click on a column header to sort the list under that column. Click the column header a second time to toggle the sort order (ascending/descending), as indicated by the Up/Down arrow.
Refresh the alarm list manually. Click the Refresh button.
