# stats
```markdown
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
```
## 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
CONTAINER CPU % MEM USAGE / LIMIT MEM % NET I/O BLOCK I/O

Running `docker stats` on multiple containers by name and id against a Linux daemon.
```bash
$ docker stats fervent_panini 5acfcb1b4fd1

```
Running `docker stats` with customized format on all (Running and Stopped) containers.
```bash
$ docker stats --all --format "table {{.ID}}\t{{.Name}}\t{{.CPUPerc}}\t{{.MemUsage}}"

`drunk_visvesvaraya` and `big_heisenberg` are stopped containers in the above example.

### 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

9c76f7834ae2 0.07% 2.746 MiB / 64 MiB
d1ea048f04e4 0.03% 4.583 MiB / 64 MiB
