Check Resources Used by each Docker Container

Question

How do you check the amount of resources (CPU, memory etc) being used by each Docker container that is running on the (Ubuntu) server?

Answer 1

you have docker stats see the doc

http://docs.docker.com/reference/commandline/stats/

for example you can do

docker stats $(docker ps -q)

(that will display the id of the containers or if you want the name, see

Is there any way to display container names in docker stats?

, you can also you docker top if you are interested in a specific container

http://docs.docker.com/reference/commandline/top/

Answer 2

this displays real-time resource usage across all running containers on a single docker engine or entire swarm cluster

docker stats $( docker ps --format '{{ .Names }}' )

sample output

CONTAINER              CPU %               MEM USAGE / LIMIT     MEM %               NET I/O               BLOCK I/O           PIDS
