Alarm States
On the Alarms page, alarms can have a combination of the following states:
| Set | NI InsightCM Server detected the rule condition and created an instance of the alarm. The level that triggered the alarm is still being detected. |
| Acknowledged | A user indicated awareness of the alarm. |
| Clear | NI InsightCM Server detected that the alarm rule is no longer true. A cleared alarm remains on the Active System Alarms or Active Trend Alarms tab until someone acknowledges it. |
The following table lists the different alarm states the NI InsightCM web application displays on the Alarms page:
| Set? | Clear? | Acknowledged? | Location on Alarms page |
|---|---|---|---|
 |
 |
|
Active System Alarms tab |
|

|
Active System Alarms tab |

|
Active System Alarms tab |
|
|
|
Alarm Instances dialog box |
Example: Alarm Transitions without Acknowledgement
To demonstrate how alarm instances transition state, consider the following illustration where an alarm is set (1) and cleared (2) twice. Assume the alarm is never acknowledged by a user. In this example, the same alarm instance remains on the Active System Alarms or Active Trend Alarms tab the entire time even though its status transitions to Clear twice.

|
 |
Alarm set |
 |
Alarm clear |
Example: Alarm Transitions with Acknowledgement
Consider the same scenario and data as in the previous section. If you acknowledge the alarm at either time indicated by (3) in the following illustration, the NI InsightCM web application moves the first alarm instance from the Active System Alarms or Active Trend Alarm tab to the Alarm Instances dialog box. When the data rises above the set point the second time, the NI InsightCM web application displays a new alarm instance on the Active System Alarms or Active Trend Alarms tab.
|
|
|
|
Alarm set |
|
Alarm clear |
 |
Times when acknowledging the alarm will cause the NI InsightCM web application to move the first alarm instance to the Alarm Instances dialog box after its status becomes Clear |
Viewing Alarm Transitions between Set and Cleared
To see the transitions of an alarm instance from Set to Clear, select the alarm on the Active System Alarms tab or Alarm Instances dialog box of the Alarms page, then find the Transitions section on the Details pane as the following figure shows.
