PRTG Manual: Alarms
The Alarm list shows all sensors that are currently 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 to keep track of all irregularities in your network.
In the table list, you can re-sort the items by clicking on the column's header items.
There are two possibilities to call the alarms list: Either you click on the Alarms tab on the detail page of a probe, group, or device (not available for sensors), or you choose the Alarms entry in the main menu.
Pages of probes, groups, device, and sensors have a tab-like interface. Using the tabs you can navigate through various sub-pages of an object in order to show your network's status, view monitoring results, or change settings.
On an object's detail view, click on the Alarms tab to show a table list of all sensors on this object that currently show a Down , Down (Partial) , Warning , or Unusual status. You will see a subset of sensors in an alarm state for the current object only. This is a subset of the entries available via the Alarms | All option in main menu. The tab is not available on a sensor's detail page.
Click the Alarms entry from the main menu to show a table list of all sensors in your configuration that currently show a Down , Down (Partial) , Down (Acknowledged) , Warning , or Unusual status. You can also show these sensors as gauges. Hover the Alarms entry and select another option to only show a subset of sensors in certain states. Choose between:
Shows a list of all sensors which currently show a Down , Down (Partial) , Down (Acknowledged) , Warning , or Unusual status.
- Show as Gauges
Shows the gauges of all sensors which currently show a Down , Down (Partial) , Down (Acknowledged) , Warning , or Unusual status. The size of the sensor gauges corresponds to their respective priority.
- Errors Only
Shows a list of all sensors which currently show a Down , Down (Partial) , or Down (Acknowledged) status.
- Warnings Only
Shows a list of all sensors which currently show a Warning status.
- Unusuals Only
Shows a list of all sensors which currently show an Unusual status.
An acknowledged alarm will show up in the alarms list as "acknowledged" (see Sensor States ) and will not trigger any more notifications. Note: If the alarm condition clears, the sensor will usually return into an Up status immediately with the next sensor scan.
In order to acknowledge an alarm, right-click on a sensor and choose Acknowledge Alarm... from the context menu, enter a message and click the OK button. The message will appear in the sensor's last message value. You can choose between: Acknowledge Indefinitely... , acknowledge For 5 Minutes... , For 15 Minutes... , For 1 Hour... , For 3 Hours... , For 1 Day... , or Until... .
If you choose Until... a popup window will appear:
Acknowledge Alarm until
Shows the sensor(s) for which you want to acknowledge the alarm. You can acknowledge alarms for more than one sensor using multi-edit.
Enter a text, for example, the reason why you acknowledge the alarm.
Enter the date when the acknowledge status will end. Use the date time picker to enter the date and time. Note: If the alarm condition still persists after the specified date, the sensor will show a Down status again.
