Docker stats

You can use the docker stats command to live stream a container’s runtime metrics. The command supports CPU, memory usage, memory limit, and network IO metrics.

The following is a sample output from the docker stats command

$ docker stats redis1 redis2
CONTAINER           CPU %               MEM USAGE / LIMIT     MEM %               NET I/O             BLOCK I/O
redis1              0.07%               796 KB / 64 MB        1.21%               788 B / 648 B       3.568 MB / 512 KB
redis2              0.07%               2.746 MB / 64 MB      4.29%               1.266 KB / 648 B    12.4 MB / 0 B
