Slack Agent alert notifications

Learn how to send notifications to a Slack workspace 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.

This is what you will get:



You will need:

  • a Slack app along with an incoming webhook, read Slack's guide on the topic here
  • one or more channels to post the messages to
  • terminal access to the Agent you wish to configure

Configure Netdata to send alert notifications to Slack


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_SLACK to YES.
  2. Set SLACK_WEBHOOK_URL to your Slack app's webhook URL.
  3. Set DEFAULT_RECIPIENT_SLACK to the Slack channel your Slack app is set to send messages to.
    The syntax for channels is #channel or channel.
    All roles will default to this variable if left unconfigured.

An example of a working configuration would be:

# slack ( global notification options
