PRTG Manual: Alarms

The alarms list shows all sensors that are in a Down, Down (Partial), Down (Acknowledged), Warning, or 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.

In the table list, you can sort the items via the column's header items.
