In this short article, we would like to show you how to display CPU and memory usage of docker containers.

1. Show stats for all docker containers

Edit

We can see CPU / memory usage and limits for all docker containers.

$ docker stats

2. Show stats for docker containers by container name

Edit

We can see CPU / memory usage and limits only for specified docker containers.
