Observing Alarms
Each alarm detail page and the alarming history page contain a list of state changes of alarms. Right after creation an alarm is disabled and needs to be enabled (turned on). After being activated it returns to the idled state which is basically the same as enabled just showing that it was activated before and which value caused the "deactivation". The activation can be acknowledged to show that the user is attending the problem or even solved it.
Possible states
| State Change | Explanation |
|---|---|
| Off | The alarm is disabled. |
| Enabled | The alarm is enabled and can now become active. |
| Idled | The alarm is enabled and waits for reaching the trigger. |
| Activated | The trigger was reached and the alarm turned active |
| Acknowledged | The occurrence of the alarm was acknowledged but the alarm is still active. |
Alarm Tracking
State changes of alarms can be found on the bottom half of the details page. Each occurrence marks one cycle from activation to the returning to the idled state. The table contains state changes, time of change and the value that lead to the change. The last column shows either a checkbox meaning the alarm activation can be acknowledged or the name of the user who already acknowledged it.
History View
The history view contains a list of all state changes that occurred on any alarm, however, it can be filtered easily using the button or the search function on the top right of the list.
Selecting one of the items in the history list leads to the details view of the according alarm.
