PRTG Manual: Notifications
PRTG uses notifications to send you alerts whenever PRTG discovers a defined status, such as slow or failing sensors, or when channels breach threshold values. You can define an unlimited number of notifications using one, or more, of several notification methods like email, text messaging, push notifications to Android and iOS devices, and many more. PRTG sends notifications to the desired user's notification contacts that you can define for each user account.
For more information, see the video tutorial: Notifications
PRTG sends a notification when a defined event triggers it. The following events can trigger notifications:
Sensor status changes
When a sensor changes its status from Up to Down or Warning because responses are slow, or when a sensor status changes to Unusual.
Sensor value threshold breaches
When a sensor shows a request time higher than 1,000 ms for more than 30 minutes, or when free disk space is below 10%.
Speed threshold breaches
When a traffic sensor shows more than 1 Mbit/s for more than 5 minutes.
Volume threshold breaches
When a traffic sensor shows more than 1 GB transferred in 24 hours.
Sensor value changes
When the value changes, for example, when monitoring files on a hard disk drive for some sensors.
A notification can use one or more of the following notification methods:
- Send Email
- Send Push Notification
- Send SMS/Pager Message
- Send Slack Message
- Send Microsoft Teams Message
- Add Entry to Event Log
- Send Syslog Message
- Send SNMP Trap
- Execute HTTP Action
- Execute Program
- Send Amazon Simple Notification Service (SNS) Message
- Assign Ticket
For details, see section Account Settings—Notification Templates.
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 add two different ways to get a notification. For example, use the latency setting of a state trigger to choose a notification with a different delivery method than in the first trigger condition, or set up a second trigger with a different notification for the corresponding object.
Notifications can contain valuable sensor information, such as:
- Last error message
- Last good/failed request
- Total downtime
- Total uptime
- Recent sensor history
- A direct link to the PRTG web interface

Overall, you have to go through four steps to use notifications.
- Check and set up the Notification Delivery settings if you use PRTG on premises. These define how PRTG sends messages.
For detailed information, see section System Administration—Notification Delivery.
- Check and set up Notification Contacts for the user accounts. These define where to send notifications.
For detailed information, see section Account Settings—Notification Contacts.
- Check and set up several Notification Templates. These define the kind of message and its content.
For detailed information, see section Account Settings—Notification Templates.
- Check and set up Notification Triggers for objects. These trigger the defined notifications.
For detailed information, see section Sensor Notification Triggers Settings.
We 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 (because of an email server outage or for other reasons), PRTG can still notify you via your smartphone in this case as a fallback. You can achieve this, for example, by using the latency setting in a state trigger and selecting a notification with a different delivery method than for the first trigger condition.
See the sections Setting Up Notifications Based on Sensor Limits: Example and Setting up Notifications Based on Libraries: Example for a step-by-step guide that describes a potential notifications setup.
Custom notification scripts are also available in the PRTG Script World.
