|
|
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
|
|
--no-trunc Don't truncate output
|
|
```
|
|
|
|
## 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.
|
|
|
|
## Examples
|
|
|
|
Running `docker stats` on all running containers against a Linux daemon.
|
|
|
|
```bash
|
|
$ docker stats
|
|
|
|

|
|
|
|
Running `docker stats` on multiple containers by name and id against a Linux daemon.
|
|
|
|
```bash
|
|
$ docker stats awesome_brattain 67b2525d8ad1
|
|
|
|

|
|
```
|
|
|
|
Running `docker stats` with customized format on all (Running and Stopped) containers.
|
|
|
|
```bash
|
|
$ docker stats --all --format "table {{.Container}}\t{{.CPUPerc}}\t{{.MemUsage}}" fervent_panini 5acfcb1b4fd1 drunk_visvesvaraya big_heisenberg
|
|
|
|
CONTAINER CPU % MEM USAGE / LIMIT
|
|
fervent_panini 0.00% 56KiB / 15.57GiB
|
|
5acfcb1b4fd1 0.07% 32.86MiB / 15.57GiB
|
|
drunk_visvesvaraya 0.00% 0B / 0B
|
|
big_heisenberg 0.00% 0B / 0B
|
|
```
|
|
|
|
`drunk_visvesvaraya` and `big_heisenberg` are stopped containers in the above example.
|
|
|
|
Running `docker stats` on all running containers against a Windows daemon.
|
|
|
|
```powershell

### 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:
|
|
|
|
```bash
|
|
$ 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:
|
|
|
|
```bash
|
|
$ docker stats --format "table {{.Container}}\t{{.CPUPerc}}\t{{.MemUsage}}"
|
|
|
|
CONTAINER CPU % PRIV WORKING SET
|
|
1285939c1fd3 0.07% 796 KiB / 64 MiB
|
|
9c76f7834ae2 0.07% 2.746 MiB / 64 MiB
|
|
d1ea048f04e4 0.03% 4.583 MiB / 64 MiB
|
|
```
|
|
|
|
The default format is as follows:
|
|
|
|
On Linux:
|
|
|
|
"table {{.ID}}\t{{.Name}}\t{{.CPUPerc}}\t{{.MemUsage}}\t{{.MemPerc}}\t{{.NetIO}}\t{{.BlockIO}}\t{{.PIDs}}"
|
|
|
|
On Windows:
|
|
|
|
"table {{.ID}}\t{{.Name}}\t{{.CPUPerc}}\t{{.MemUsage}}\t{{.NetIO}}\t{{.BlockIO}}"
|
|
|
|
|
|
> **Note**: On Docker 17.09 and older, the `{{.Container}}` column was used, in
|
|
> stead of `{{.ID}}\t{{.Name}}`.
