Historical Alarms

Prerequisites

• By default, 20,000 historical alarms can be displayed. When the number of alarms exceeds the upper limit, the first 20,000 alarms are displayed based on the filter criteria and sorting. If you want to query other alarms, you can modify the filter criteria and sort the alarms.
• You can only monitor and view alarms of authorized MOs.
• A total number of 30 Historical Alarms pages can be opened concurrently by online users.

Procedure

1. Choose Device Management > Alarm Management > Historical Alarms.
2. On the Historical Alarms page, click Filter to expand the panel and set filter criteria to find desired historical alarms.
3. Click Save or Save As to save the current filter criteria as a filter template.

   You can click Template Management in the upper left corner of the page to view all filter templates and select a filter template from the Quick Filter panel. Users with the Administrators role can manage templates saved by all users.

   The following types of templates are provided:

   • Favorite: You can add the templates that you often use to your favorites.
