Summary: |
This article explains the conditions for setting and clearing alarms. |
Alarm states and whether you acknowledge or clear the alarm determine the notification behavior of your configured alarms.
Once you begin collecting data, define conditions that set or clear an alarm. Alarms can have a combination of the following states.
|
Set |
InsightCM detected that conditions for an alarm rule have been met and created an alarm instance. |
|
Acknowledged |
A user indicated awareness of the alarm. |
|
Clear |
InsightCM detected that the alarm rule is no longer true. A cleared alarm remains on the Active Trend Alarms tab or Active Spectral Alarms tab until you acknowledge it. |
The following table lists the different alarm states the web application displays on the Alarms page.
To demonstrate how an alarm enters a Set state, consider the following illustration where an alarm is set and cleared twice. Assume that you never acknowledged the alarm. In this example, the same alarm instance remains on the Active Trend Alarms tab or Active Spectral Alarms tab the entire time even though its status transitions to Clear twice. Since the first instance of the alarm was not acknowledged, InsightCM collects no additional data sets and issues no new notification when the alarm enters the Set state the second time.
Consider the same scenario and data as in the previous section. If you acknowledge the alarm at either time indicated by 
in the following illustration, the web application moves the first alarm instance from one of the Active Alarms tab to the Alarm Instances dialog. When the data crosses the set threshold the second time, the web application displays a new alarm instance an Active Alarms tab.
