The status or the data of a sensor can trigger notifications. Using this mechanism, you can configure external alerting tailored to your needs.

Example of Notification Trigger Settings

Example of Notification Trigger Settings

Although the sensors activate a notification trigger, you can set notification triggers higher in the hierarchy (for example, for groups or devices). Because of this you can define notification triggers for multiple sensors using the inheritance mechanism. Monitoring objects with inherited notification triggers show these in section Triggers That Can Be Inherited From Parent Object(s) on the Notification Triggers tab.

PRTG already includes a default notification trigger for the Root Group. This default notification trigger provokes the standard notification Email and push notification to admin if there is any sensor in a Down status in your PRTG installation for at least 10 minutes.

You can also define notification triggers in Libraries. Sensors that are in a library with defined notification triggers show these notification triggers in section Triggers That Are Defined in Library Object(s) on the Notification Triggers tab.

Note

This section describes one of four steps to set up the notification system in PRTG. To complete your notification setup, go through all of the following steps:

  1. Check and set up the Notification Delivery settings to define how and to which recipient PRTG will send messages.
    For detailed information, see section System Administration—Notification Delivery.
  2. Check and set up Notification Contacts for the PRTG users to define the recipients of notifications.
    For detailed information, see section Account Settings—Notification Contacts.
  3. Check and set up Notification Templates to define the notification methods and their content.
    For detailed information, see section Account Settings—Notification Templates.
    icon-i-roundYou can also check or edit notification templates via the Notification Triggers tab. For more information, see section Sensor Notification Triggers Settings.
  4. Check and set up Notification Triggers for objects to define when notification messages will be sent.
    For detailed information, see section Sensor Notification Triggers Settings.

icon-i-roundWe recommend that you always set up at least two notifications with different delivery methods for a notification trigger, for example, one email notification and one SMS notification. If delivery via email fails (due to an email server failure or other reasons), PRTG can still notify you via your smartphone. Simply set your latency setting to a state trigger and a notification via a delivery method other than the one for the first trigger. Or set up a second trigger with another notification for the corresponding object.

icon-book-arrowsFor background information, see section Notifications.

Available Notification Triggers Settings

On an object's detail page, open the Notification Triggers tab to change sensor notification triggers. The available options are the same for all objects. When defining triggers for probes, groups, or devices, they can be inherited down to sensor level.

Triggers that can be inherited from parent object(s)

You see a list of all notification triggers that are defined higher in the hierarchy. The list is empty and shows the message (no triggers defined) when you have not set any triggers in probes, groups, or devices above the current object in the Object Hierarchy. You can see the Type of trigger and the notification Rule that the monitoring object executes once this trigger is activated.

Trigger Inheritance

Define the triggers you want to use for the current object. Choose between:

  • Inherit all triggers from parent objects and use the triggers defined above: Use the triggers shown in the list of inherited triggers and use the specific triggers for this object defined above in section Notification Triggers. If the defined conditions are met, the corresponding triggers are activated and the notifications provoked. To change settings of the specific notification triggers for this object, click the Edit button to the right of it. To change settings of the inherited notification triggers, click the name of the monitoring object in the column Inherited from to open its Overview tab and then open the Notification Triggers tab.
  • Only use the triggers defined above: Do not use the inherited triggers shown in the list. Only use the triggers that you define above in section Notification Triggers for this object.

This setting is valid for all triggers shown above and in the list of inherited triggers. It is not possible to select only some of the triggers.

In section Triggers that are defined in library object(s), you see all notification triggers that are set for Libraries that contain the currently selected sensor.

Triggers that Are Defined in Library Object(s)

You see a list of all notification triggers that are defined in libraries that include the currently selected sensor. The list is empty and shows the message (no triggers defined) when you have not set any triggers in libraries that contain the current sensor. You can see the Type of trigger and the notification Rule that the sensor executes once this trigger is activated.

Click the notification name to directly change its settings. Click a library name in the column Inherited from to view this library.

icon-i-roundYou cannot turn off trigger usage for the current sensor from a library here. If you do not want to use any notification triggers from a library for this sensor, open the library and remove this sensor from it or refine the triggers on the Notification Triggers tab.

You can set up one or more of the following triggers, each with different setting options. Which trigger types are visible depends on the kind of object you edit:

You can create all notification triggers by forming sentences in "natural language". There are different options available for every type.

Add State Trigger

Define a trigger that is activated when a sensor changes its current status. This is the most common reason to send out notifications. Hover over plus_button and select Add State Trigger from the menu to add a new trigger, or click the Edit button next to an existing trigger to change it. You can also directly edit notification templates via the Edit Notification Template button next to a notification template. Define the settings as described below. Every trigger provokes one or more notification(s) to be executed.

State Trigger

When sensor state is [...]

Select the status that will trigger the notification. The trigger will be activated when a sensor enters the selected status. Choose from the dropdown menu:

  • Down: The trigger is activated if a sensor changes to a Down status.
  • Warning: The trigger is activated if a sensor changes to a Warning status.
  • Unusual: The trigger is activated if a sensor changes to an Unusual status.
  • Partial Down: The trigger is activated if a sensor changes to a Down (Partial) status (available in a cluster configuration).
  • Up: The trigger is activated if a sensor changes to an Up status.
  • Unknown: The trigger is activated if a sensor changes to an Unknown status.

...for at least [...] seconds,

Define how many seconds PRTG waits before it sends out a notification (latency). This can avoid false alarms if a sensor 'flickers' and, for example, changes to a down status for just a few seconds. If the sensor status persists after the defined time in seconds, the notification is triggered. Please enter an integer value.

icon-i-round-redDo 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 a notification that PRTG sends out if the selected sensor status is true and the latency time defined has elapsed. Choose a notification template from the dropdown menu. The menu shows all notification templates defined in the Account Settings—Notification Templates settings. Use the search box to filter for existing notification templates. You can also choose no notification to only use other conditions for this trigger.

When sensor state is [...] for at least [...] seconds

Define an escalation latency in seconds. This "escalation" triggers a second notification if the number of seconds you enter here has passed since the sensor status has entered the defined condition. Use this to automatically escalate a notification in case a problem persists for a longer time. Please enter an integer value.

icon-i-roundPRTG automatically takes the status from the first trigger condition above.

...perform [...]

Select a (second) notification that PRTG sends out if the selected sensor status is true and the escalation latency time defined has elapsed. Choose a notification template from the dropdown menu. The menu shows all notification templates defined in the Account Settings—Notification Templates settings. Use the search box to filter for existing notification templates. You can also choose no notification to only use other conditions for this trigger.

icon-i-roundSelect a notification with another delivery method than above to ensure the delivery in case of technical issues with the first notification.

...and repeat every [...] minutes

Define an interval in minutes in which PRTG sends the escalation notification (defined above) repeatedly. The second (escalation) notification defined will be resent every x minutes that you enter here. Please enter an integer value.

icon-i-roundIf you enter 0, PRTG will not send repeating escalation notifications.

When sensor leaves [...] state after a notification was triggered, perform [...]

Select a notification that PRTG sends out if the selected sensor status is not true anymore because the sensor status changed again. Choose a notification template from the dropdown menu. The menu shows all notification templates defined in the Account Settings—Notification Templates settings. Use the search box to filter for existing notification templates. You can also choose no notification to only use other conditions for this trigger.

icon-i-roundPRTG sends notifications about cleared states if the time for the trigger activation elapsed (defined in the first line) and you choose a notification here. If you select no notification above, you will get the notification about the cleared status nevertheless if you define it here. The definition of an "escalation" notification does not influence notifications for cleared conditions.
