Prowl Agent alert notifications

Learn how to send notifications to Prowl using Netdata's Agent alert notification feature, which supports dozens of endpoints, user roles, and more.


This file assumes you have read the Introduction to Agent alert notifications, detailing how the Netdata Agent's alert notification method works.

Prowl is a push notification service for iOS devices.
Netdata supports delivering notifications to iOS devices through Prowl.

Because of how Netdata integrates with Prowl, there is a hard limit of at most 1000 notifications per hour (starting from the first notification sent). Any alerts beyond the first thousand in an hour will be dropped.

Warning messages will be sent with the 'High' priority, critical messages will be sent with the 'Emergency' priority, and all other messages will be sent with the normal priority. Opening the notification's associated URL will take you to the Netdata dashboard of the system that issued the alert, directly to the chart that it triggered on.


You will need:

  • a Prowl API key, which can be requested through the Prowl website after registering
  • terminal access to the Agent you wish to configure

Configure Netdata to send alert notifications to Prowl


This file mentions editing configuration files.

  • To edit configuration files in a safe way, we provide the edit config script located in your Netdata config directory (typically is /etc/netdata) that creates the proper file and opens it in an editor automatically.
    Note that to run the script you need to be inside your Netdata config directory.

It is recommended to use this way for configuring Netdata.

Edit health_alarm_notify.conf, changes to this file do not require restarting Netdata:

  1. Set SEND_PROWL to YES.
  2. Set DEFAULT_RECIPIENT_PROWL to the Prowl API key you want the alert notifications to be sent to.
    You can define multiple API keys like this: APIKEY1, APIKEY2.
    All roles will default to this variable if left unconfigured.

You can then have different API keys per role, by editing DEFAULT_RECIPIENT_PROWL with the API keys you want, in the following entries at the bottom of the same file:


An example of a working configuration would be:

# iOS Push Notifications
