Montioring Synology's Docker Daemon with Prometheus

October 20, 2019

Docker can be configured to expose Prometheus formated metrics, to enable this functionality you need to add the following to /var/packages/Docker/etc/dockerd.json :

{
  "experimental" : true,
  "metrics-addr" : "0.0.0.0:9999",
}

Once updated, restart your Docker package for the changes to take effect.
