==> Pouring prometheus-2.7.1.sierra.bottle.tar.gz
==> Caveats
When used with `brew services`, prometheus' configuration is stored as command line flags in
  /usr/local/etc/prometheus.args

Example configuration:
  echo "--config.file ~/.config/prometheus.yml" > /usr/local/etc/prometheus.args


To have launchd start prometheus now and restart at login:
  brew services start prometheus
Or, if you don't want/need a background service you can just run:
  prometheus
