Resource consumption inside a Docker container

CONTAINER      CPU %    MEM USAGE / LIMIT     MEM %    NET I/O             BLOCK I/O           PIDS
48c16e180af6   0.20%    91.48MiB / 31.31GiB   0.29%    3.86kB / 0B         85.3MB / 0B         33

Does anyone know how to get resource consumption of a specific Docker container within its running environment?

Outside of a container, we can get it easily by typing a command "docker stats". Besides, if I try to get resource consumption inside a container, it will get the consumption (RAM, CPU) of the physical computer which the container runs on. Another option is using 'htop' command, but it does not show the result exactly compared to 'docker stats' command.

If you want the processes consumption inside the container, you can go into the container and monitor the processes.

docker exec -it <container-name> watch ps -aux

Notice that after running the above command, the container doesn't know about any docker processes running.
