PRTG Manual: Notification Triggers Settings

<%NUMBERING1%>.<%NUMBERING2%>.<%NUMBERING3%> PRTG Manual: Notification Triggers Settings

You can use changes in a sensor's status or in the sensor's data to trigger notifications.

Notification Triggers Tab

Although sensors activate notification triggers, you can set notification triggers in the settings of objects that are higher in the object hierarchy. This allows you to use the inheritance of settings to define notification triggers for multiple sensors. Objects that inherit notification triggers show them on the Notification Triggers tab.
For more information, see section Triggers That Can Be Inherited from Parent Objects.

You can also define notification triggers in libraries. If a sensor is in a library that has notification triggers, the sensor shows them on the Notification Triggers tab.
For more information, see section Triggers That Are Defined in Libraries.

You can also directly edit notification templates on the Notification Triggers tab. To do so, click next to name of a notification template.

Note

You must take the following four steps to set up and use notifications:

Check and set up the notification delivery settings if you use PRTG Network Monitor. These settings define how PRTG sends messages.
Check and set up notification contacts for the user accounts. These contacts define the recipients to which PRTG sends notifications.
Check and set up several notification templates. These templates define the notification methods and their content.
You can also check or edit notification templates via the Notification Triggers tab. For more information, see section Notification Triggers Settings.
Check and set up notification triggers settings for objects. These triggers define when PRTG sends notifications.

Usually, there are three successive attempts to deliver a notification. If all of these attempts fail, the notification is lost. To never miss a notification, we recommend that you always set up at least two notifications with different notification methods for a notification trigger, for example, one email notification and one SMS notification. If delivery via email fails, PRTG can still notify you via smartphone as a fallback. For example, use the latency setting of a state trigger to choose a notification with a different notification method than in the first trigger condition, or set up a second trigger with a different notification method for the corresponding object.

For a detailed step-by-step guide, see the Paessler website: How to set up notifications via the PRTG web interface.

Custom notification scripts are also available in the PRTG Sensor Hub.

Notification Triggers

Select the Notification Triggers tab of an object to add or edit notification triggers. You can set up one or more of the following notification triggers:

Different options are available for every notification trigger. You see the Type of notification trigger and the notification Rule that the sensor executes once it activates a notification trigger.

Which notification triggers are available on the Notification Triggers tab depends on the kind of object you select.

State Trigger

The state trigger performs a notification when a sensor changes its status. Hover over and select Add State Trigger from the menu to add a new state trigger or click next to a state trigger to change it.

Add State Trigger

PRTG includes a state trigger for the root group by default. This notification trigger performs the notification Email and push notification to admin if any sensor is in the Down status for at least 10 minutes.

Setting	Description
When sensor state is [...]	Select the status that triggers a notification: Down: Trigger a notification if a sensor changes to the Down status. Warning: Trigger a notification if a sensor changes to the Warning status. Unusual: Trigger a notification if a sensor changes to the Unusual status. Down (Partial): Trigger a notification if a sensor changes to the Down (Partial) status. This status is only possible in a failover cluster. Up: Trigger a notification if a sensor changes to the Up status. Unknown: Trigger a notification if a sensor changes to the Unknown status.
for at least [...] seconds,	Enter the time in seconds that PRTG waits before it sends a notification (latency). This can avoid false alarms if, for example, a sensor changes to the Down status for only a few seconds. Enter an integer. Do not define a latency that is shorter than the scanning interval of a sensor that uses this trigger. The notification trigger might not work as expected in this case.
perform [...]	Select the notification that PRTG sends if the sensor is in the selected status and if the defined latency is over. You see all notification templates that you have defined under Setup \| Account Settings \| Notification Templates. Use the search box to filter for notification templates. You can also select no notification to not send a notification in this case. You can also directly create and use new notification templates by clicking in the dropdown list.
When sensor state is [...] for at least [...] seconds	Enter the escalation latency in seconds that PRTG waits before it sends an escalation notification. Use this to automatically escalate a notification if a problem exists for a longer time. Enter an integer. PRTG automatically fills in the selected status.
perform [...]	Select the notification that PRTG sends if the sensor is still in the selected status and if the defined escalation latency is over. You see all notification templates that you have defined under Setup \| Account Settings \| Notification Templates. Use the search box to filter for notification templates. You can also select no notification to not send a notification in this case. Select a notification with a different delivery method than in the first trigger condition to make sure that you receive a notification in case the first notification could not be sent. You can also directly create and use new notification templates by clicking in the dropdown list.
and repeat every [...] minutes	Enter the interval in minutes after which PRTG sends the escalation notification again. Enter an integer. If you enter 0, PRTG does not send the escalation notification again.
When sensor state is no longer [...] , perform [...]	Select the notification that PRTG sends if the sensor is no longer in the selected status and if the defined latency is over. You see all notification templates that you have defined under Setup \| Account Settings \| Notification Templates. Use the search box to filter for notification templates. You can also select no notification to not send a notification in this case. PRTG automatically fills in the selected status. You can also directly create and use new notification templates by clicking in the dropdown list.
