PRTG Manual: Alarms

You can see all sensors that are in the Down, Down (Partial), Down (Acknowledged), Warning, or the Unusual status. Sensors in other states, for example, Up, Paused, or Unknown, do not appear here. This is useful for keeping track of all irregularities in your network.

i_round_blueBy default, table lists that show alarms are sorted by priority. Click a column header to sort the list items by a different category.

Alarms List

Alarms List

There are two ways to display the alarms list. Either click the Alarms tab of a probe, group, or device, or click Alarms in the main menu bar.

Alarms (Object Tab)

Probe, group, device, and sensor pages have tabs that you can use to navigate between the different options. For example, you can view your network's status, view monitoring results, or change settings.

Tabs Bar for Groups and Probes

Tabs Bar for Groups and Probes

Click the Alarms tab of a probe, group, or device to show a table list of all sensors on the selected object that show the Down, Down (Partial), Down (Acknowledged), Warning, or Unusual status. This list is a subset of the entries that are available via the Alarms | All option in the main menu bar.

Acknowledge Alarm

An acknowledged alarm shows the Down (Acknowledged) status. It does not trigger any more notifications.
