Drone is compatible with Prometheus and exposes a `/metrics` endpoint. Please note that access to the metrics endpoint is restricted and requires an authorization token with administrative privileges. ```nohighlight global: scrape_interval: 60s scrape_configs: - job_name: 'drone' bearer_token: eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9... static_configs: - targets: ['drone.domain.com'] ``` # Authorization An administrator will need to generate a user api token and configure in the prometheus configuration file as a bearer token. Please see the following example: ```diff global: scrape_interval: 60s scrape_configs: - job_name: 'drone' + bearer_token: eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9... static_configs: - targets: ['drone.domain.com'] ``` #
