stats

Usage:  docker stats [OPTIONS] [CONTAINER...]

Display a live stream of container(s) resource usage statistics

Options:
  -a, --all             Show all containers (default shows just running)
      --format string   Pretty-print images using a Go template
      --help            Print usage
      --no-stream       Disable streaming stats and only pull the first result

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.

Examples

Running docker stats on all running containers against a Linux daemon.

$ docker stats

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}}"
