Docker has a built-in stats command that makes it simple to see the amount of resources your containers are using. Just drop $ docker stats in your CLI and you’ll get a read out of the CPU, memory, network, and disk usage for all your running containers.
To use the command, open a terminal and run the docker stats command: $ docker stats CONTAINER CPU % MEM USAGE / LIMIT MEM % NET I/O BLOCK I/O redis1 0.07% 796 KB / 64 MB redis2 0.07%
Docker stats is a useful command that provides information about the resources your containers are using at a given point in time.
The Resource Usage extension shows which containers consume the most resources on their development machines by running the Docker stats command, then compiling the data into a user interface.
