Find Memory consumption of the container by using commands inside the container

Question

Hello

I am trying to use Healthcheck in the container. Want to make the container unhealthy when the memory consumption reaches 90%. Is there anyway to do that.

Hi,

You can use any monitoring tools like ELK or Grafana. This will give you a user-friendly graph in real-time. Or you can retrieve the metrics of your docker container. By default it is disabled. But you can enable this by using the below-given steps.

• 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.
