  2. From the left navigation pane click Alarm Management and select Alarms.

The Alarm Dashboard page is displayed. Use this dashboard to view the state of alarms across your monitored environment and take immediate action on them. It shows alarm counts by time, allowing you to identify excessive alarm counts or outage events.

Alarms Analysis

The Alarm Analysis view is to provide a snapshot of alarms and to help you investigate top issues in your environment, so you can more proactively manage your alerts, thresholds, and monitored system. The alarm count in this view includes SLA alarms.

The maximum number of alarms for the selected time range is set to 5000 by default. To change this value, type the number in the Max Number of Evaluated Alarms field, and then click Apply.

The Max Number of Evaluated Alarms is scaled from 0 to 100,000 and is managed by the Alarm_Analysis_Max_Object variable. To change the value of this variable, search for and edit Alarm_Analysis_Max_Object from Dashboards > Administration > Rules & Notifications > Manage Registry Variables.

The Alarms Analysis (Preview) view contains the following elements:

  • Alarms by Source: Lists all alarms (cleared or non-cleared) that are triggered by the alarm source. For more information about alarm sources, click Dashboards > Administration > Rules & Notifications > Rules. Click an alarm source to display a popup and see more detailed information about an alarm. For more information, see Viewing Alarm.

  • Counts by Severity chart: Summarizes the totals for each severity of alarm (Warning, Critical, or Fatal) and the total number of alarms.


Alarm(s) for the Entire System
