`--no-stream`		Disable streaming stats and only pull the first result

Parent command

docker	The base command for the Docker CLI.

Extended description

The docker stats command returns a live data stream for running containers. To limit data to one or more specific containers, specify a list of container names or ids separated by a space. You can specify a stopped container but stopped containers do not return any data.

If you want more detailed information about a container’s resource usage, use the /containers/(id)/stats API endpoint.

Formatting

The formatting option (--format) pretty prints container output using a Go template.

Valid placeholders for the Go template are listed below:

Placeholder	Description
`.Container`	Container name or ID (user input)
`.Name`	Container name
`.ID`	Container ID
`.CPUPerc`	CPU percentage
`.MemUsage`	Memory usage
`.NetIO`	Network IO
`.BlockIO`	Block IO
`.MemPerc`	Memory percentage (Not available on Windows)
`.PIDs`	Number of PIDs (Not available on Windows)

When using the --format option, the stats command either outputs the data exactly as the template declares or, when using the table directive, includes column headers as well.

The following example uses a template without headers and outputs the Container and CPUPerc entries separated by a colon for all images:

$ docker stats --format "{{.Container}}: {{.CPUPerc}}"

09d3bb5b1604: 6.61%
9db7aa4d986d: 9.19%
3f214c61ad1d: 0.00%

To list all containers statistics with their name, CPU percentage and memory usage in a table format you can use:

$ docker stats --format "table {{.Container}}\t{{.CPUPerc}}\t{{.MemUsage}}"
