Generic alerts integration

Version history

GitLab can accept alerts from any source via a generic webhook receiver. When you set up the generic alerts integration, a unique endpoint will be created which can receive a payload in JSON format, and will in turn create an issue with the payload in the body of the issue. You can always customize the payload to your liking.

The entire payload will be posted in the issue discussion as a comment authored by the GitLab Alert Bot.

Note In GitLab versions 13.1 and greater, you can configure External Prometheus instances to use this endpoint.

Setting up generic alerts

To obtain credentials for setting up a generic alerts integration:

  • Sign in to GitLab as a user with maintainer permissions for a project.
  • Navigate to the Operations page for your project, depending on your installed version of GitLab:
    • In GitLab versions 13.1 and greater, navigate to Settings > Operations in your project.
    • In GitLab versions prior to 13.1, navigate to Settings > Integrations in your project. GitLab will display a banner encouraging you to enable the Alerts endpoint in Settings > Operations instead.
  • Click Alerts endpoint.
  • Toggle the Active alert setting to display the URL and Authorization Key for the webhook configuration.

Customizing the payload

You can customize the payload by sending the following parameters. All fields other than title are optional:

Property Type 説明
title String The title of the incident. Required.
description String A high-level summary of the problem.
start_time DateTime The time of the incident. If none is provided, a timestamp of the issue will be used.
service String The affected service.
monitoring_tool String The name of the associated monitoring tool.
hosts String or Array One or more hosts, as to where this incident occurred.
severity String The severity of the alert. Must be one of critical, high, medium, low, info, unknown. Default is critical.
fingerprint String or Array The unique identifier of the alert. This can be used to group occurrences of the same alert.

You can also add custom fields to the alert’s payload. The values of extra parameters are not limited to primitive types, such as strings or numbers, but can be a nested JSON object. For example: 

{ "foo": { "bar": { "baz": 42 } } }
Payload size: Ensure your requests are smaller than the payload application limits.

Example request: 

curl --request POST \
  --data '{"title": "Incident title"}' \
  --header "Authorization: Bearer <authorization_key>" \
  --header "Content-Type: application/json" \
  <url>

The <authorization_key> and <url> values can be found when setting up generic alerts.

Example payload: 

{
  "title": "Incident title",
  "description": "Short description of the incident",
  "start_time": "2019-09-12T06:00:55Z",
  "service": "service affected",
  "monitoring_tool": "value",
  "hosts": "value",
  "severity": "high",
  "fingerprint": "d19381d4e8ebca87b55cda6e8eee7385",
  "foo": {
    "bar": {
      "baz": 42
    }
  }
}

Automatic grouping of identical alerts

Introduced in GitLab Premium 13.2.

In GitLab versions 13.2 and greater, GitLab groups alerts based on their payload. When an incoming alert contains the same payload as another alert (excluding the start_time and hosts attributes), GitLab groups these alerts together and displays a counter on the Alert Management List and details pages.
