Hi@akhtar,

By default, docker will not allow you to monitor its metrics. For that you have to configure your docker. You can use the below code to configure your docker engine.

• Go to your /etc/docker folder and create one file named daemon.json. Inside this file write down these below lines.

{
  "metrics-addr" : "0.0.0.0:9323",
  "experimental" : true
}

• After that restart your docker engine.

$ systemctl restart docker.

• Now you can browse your docker metrics.

$ localhost:9323/metrics

Hope this is helpful.
