How to Shutting down Prometheus?

Prometheus is a standard Unix binary, so can be asked to shutdown using a SIGTERM. You will need to know the process id of Prometheus, which you might be able to find with pgrep -f prometheus or in a file such as /var/run/prometheus.pid depending on your setup. Then you can run:

$ kill -TERM 1234
where 1234 is the pid.

$ curl -X POST http://localhost:9090/-/quit #  (when the --web.enable-lifecycle flag is enabled).

Prometheus help


$ ./prometheus -h
