MultiProbe retains a complete record of alarm events in an archive that can be browsed and filtered.

To open the alarm event history, go to the Retrospectives screen, navigate to the Analytics section, and select Alarm history.

Figure 238. Alarm history screen

The screen shows a filtered list of alarm events based on the selected time range and location. The list contains the following columns:

• Alarm category icon — the alarm category (see Table 28).
• Alarm — the name of the alarm event.
• Monitoring object — the monitoring object for which the event was registered.
• Node — the node where the monitoring object is located.
• Detected — date and time the alarm was detected (to the second).
• Duration — duration of the event (to the second).
• Finished — date and time the event ended (to the second).

To filter by location, select the desired location in the location tree on the right and click Apply.

To set the time range, use the Time control bar at the top of the list. Its controls are described in Table 35 below.
