(Version >= 1.21.0)

API keys can be enabled to manage access to the Prometheus metrics endpoint.

By default, HTTP basic authentication is used to secure access to the Prometheus metrics endpoint. As soon as you add your first API key, the use of basic authentication for the endpoint will be permanently disabled.

Adding an API key

Management of API keys is done through the API Keys page in settings This page will show you all of your API keys, including expired keys.

You can set the name of the key, as well as it's expiry date, or optionally set the key to never expire. When you click generate, you will be shown the API key in a pop up dialog, you should make sure to make a copy of the key as it will not be shown again. The API key cannot be used to access the web interface but you should treat API keys like you treat your passwords as they can still be used to access potentially sensitive data.

Disabling keys

It is possible to temporarily disable keys. This can be done through the settings page. This will prevent the key from being used for authentication until it is enabled again.

Expired keys

If a key has expired, it will not be automatically deleted. This is to aid in debugging systems that suddenly stop working. You can delete an expired key, or any key for that matter, by simply hitting the red delete button from the settings page.

Authenticating using an API key

Authentication is done by passing the API key in the Authorization header. For example, here is a request made with curl to the metrics endpoint.

curl -u":<key>" uptime.kuma/metrics

Note

: is required before the key, because basic authentication requires a username and password separated by a :. We don't make use of the username field.

Here is an example config for Prometheus:

  - job_name: 'uptime'
    scrape_interval: 30s
    scheme: http
    static_configs:
      - targets: ['uptime.url']
    basic_auth: 
      password: <api key>
