Management API

Prometheus provides a set of management APIs to facilitate automation and integration.

Health check

GET /-/healthy
HEAD /-/healthy

This endpoint always returns 200 and should be used to check Prometheus health.

Readiness check

GET /-/ready
HEAD /-/ready

This endpoint returns 200 when Prometheus is ready to serve traffic (i.e. respond to queries).

Reload

PUT  /-/reload
POST /-/reload

This endpoint triggers a reload of the Prometheus configuration and rule files. It's disabled by default and can be enabled via the --web.enable-lifecycle flag.

Alternatively, a configuration reload can be triggered by sending a SIGHUP to the Prometheus process.

Quit

PUT  /-/quit
POST /-/quit

This endpoint triggers a graceful shutdown of Prometheus. It's disabled by default and can be enabled via the --web.enable-lifecycle flag.

Alternatively, a graceful shutdown can be triggered by sending a SIGTERM to the Prometheus process.
