ntfy agent alert notifications
Learn how to send alerts to an ntfy server 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.
ntfy (pronounce: notify) is a simple HTTP-based pub-sub notification service. It allows you to send notifications to your phone or desktop via scripts from any computer, entirely without signup, cost or setup. It's also open source if you want to run your own server.
This is what you will get:
You will need:
- (Optional) A self-hosted ntfy server, in case you don't want to use https://ntfy.sh
- A new topic for the notifications to be published to
- terminal access to the Agent you wish to configure

This file mentions editing configuration files.
- To edit configuration files in a safe way, we provide the
edit configscript 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.

DEFAULT_RECIPIENT_NTFYto the URL formed by the server-topic combination you want the alert notifications to be sent to. Unless you are hosting your own server, the server should always be set to https://ntfy.sh
You can define multiple recipient URLs like this:
All roles will default to this variable if left unconfigured.
All topics published on https://ntfy.sh are public, so anyone can subscribe to them and follow your notifications. To avoid that, ensure the topic is unique enough using a long, randomly generated ID, like in the following examples.
An example of a working configuration with two topics as recipients, using the https://ntfy.sh server would be:
You can then have different servers and/or topics per role, by editing
DEFAULT_RECIPIENT_NTFY with the server-topic combination you want, in the following entries at the bottom of the same file:
