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.
||InsightCM detected that conditions for an alarm rule have been met and
created an alarm instance.
||A user indicated awareness of the alarm.
Acknowledging an alarm does not clear it, so that if
the conditions for setting the alarm are met again, a new
alarm instance is not logged.
||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.

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

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

||Times when acknowledging the alarm will cause the web application to move the first alarm instance to the Alarm Instances
dialog box after its status becomes Clear.

To see the timestamps of an alarm entering Set, Cleared, or
Acknowledged states, double-click the alarm instance on the
