docker stats command tutorial
The docker stats command can be used to dynamically display the resource consumption of Docker containers , including: CPU, memory, and network I/O. The docker stats command can also specify stopped containers, but will not return any information.
docker stats command syntax
haicoder(www.haicoder.net)# docker stats [options] [container...]
docker stats command parameters
| parameter | describe |
|---|---|
| –all, -a | View all container information (running ones are displayed by default). |
| –format | Go templates display image information. |
| –no-stream | Do not display some dynamic information of the container. |
the case
View non-running container information
Use the docker create -it command to create a dokcer container.
haicoder(www.haicoder.net)# docker create -it --name haicoder centos

Use the docker stats command to view information about a specified container.
haicoder(www.haicoder.net)# docker stats haicoder
At this point, the terminal displays the following:
That is, the container's CPU, memory, network I/O and other information are listed at this time, because the container is not running, so no information is output.
Use **docker kill** and docker rm commands to remove all containers.
haicoder(www.haicoder.net)# docker kill `docker ps -qa` ; docker rm `docker ps -aq`
View running container information
Use the docker run -it command to run a docker container.
haicoder(www.haicoder.net)# docker run -it -d --name haicoder centos

Use the docker stats command to view information about running containers.
haicoder(www.haicoder.net)# docker stats haicoder
At this point, the terminal displays the following:
CPUThat is, the container , memory, network I/O and other information are output at this time . Finally, we use the docker kill and docker rm commands to remove all containers.
haicoder(www.haicoder.net)# docker kill `docker ps -qa` ; docker rm `docker ps -aq`
View all container information
Using the docker run -it command, run three dokcer containers.
haicoder(www.haicoder.net)# docker run -it -d --name haicoder centos

haicoder(www.haicoder.net)# docker run -it -d --name HaiCoder centos

Use the docker stats --all command to view information about all containers.
haicoder(www.haicoder.net)# docker stats --all
At this point, the terminal displays the following:
That is, the CPU, memory, network I/O and other information of all containers are output at this time. Finally, we use the docker kill and docker rm commands to remove all containers.
haicoder(www.haicoder.net)# docker kill `docker ps -qa` ; docker rm `docker ps -aq`
Only display static information
Using the docker run -it command, run three dokcer containers.
haicoder(www.haicoder.net)# docker run -it -d --name haicoder centos

haicoder(www.haicoder.net)# docker run -it -d --name coder centos

haicoder(www.haicoder.net)# docker run -it -d --name HaiCoder centos

Use the docker stats command to view only the static information of the container.
haicoder(www.haicoder.net)# docker stats --no-stream
At this point, the terminal displays the following:
That is, the CPU, memory, network I/O and other information of all containers are output at this time, but it is not in a dynamic form, but only the latest information is displayed.
Use the docker kill and docker rm commands to remove all containers.
haicoder(www.haicoder.net)# docker kill `docker ps -qa` ; docker rm `docker ps -aq`
docker stats command output
| output | describe |
|---|---|
| CONTAINER | Displays the ID of the container in short format. |
| CPU % | CPU usage. |
| MEM USAGE / LIMIT | The currently used memory and the maximum available memory. |
| MEM % | Displays memory usage as a percentage. |
| NET I/O | Network I/O data. |
| BLOCK I/O | Disk I/O data. |
| PIDS | PID number. |
docker stats command summary
The docker stats command can be used to dynamically display the resource consumption of Docker containers, including: CPU, memory, and network I/O.
The docker stats command can also specify stopped containers, but will not return any information.
The docker stats command uses the --all parameter to list information about all containers. The docker stats command uses the --no-stream parameter to view only the static information of the container.
