I used the following Docker command:
docker stats --all
You can change the --all
with -a
which would do the same.
This command would provide you to a nice live stream of very useful information like the CPU usage, the RAM usage, the NET I/O and more. The output would looke something like this:
CONTAINER ID NAME CPU % MEM USAGE / LIMIT MEM % NET I/O BLOCK I/O PIDS
b253d4071124 reverent_joliot 0.40% 1.703MiB / 3.853GiB 0.04% 688kB / 15.8MB 75MB / 0B 2
379cb50f3492 sharp_roentgen 0.00% 0B / 0B 0.00% 0B / 0B 0B / 0B 0
That way you could find out which container is using most of the resources on your server and possibly implement some resource limitations.
If you would like to check the resource usage for a specific container you could run:
docker stats CONTAINER_ID
If you would like to see only specific columns, you could use the --format
argument:
docker stats --format "{{.Container}}: {{.CPUPerc}}"
This would return something like:
b253d4071124 0.40%
Here is a quick video demo on how to do that as well:
For more information, I would suggest checking the official documentation here:

Hope that this helps!
