# 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
--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 need more detailed information about a container's resource usage, use
the `/containers/(id)/stats` API endpoint.
> **Note**
>
> On Linux, the Docker CLI reports memory usage by subtracting cache usage from
> the total memory usage. The API does not perform such a calculation but rather
> provides the total memory usage and the amount from the cache so that clients
> can use the data as needed. The cache usage is defined as the value of
> `total_inactive_file` field in the `memory.stat` file on cgroup v1 hosts.
>
> On Docker 19.03 and older, the cache usage was defined as the value of `cache`
> field. On cgroup v2 hosts, the cache usage is defined as the value of
> `inactive_file` field.
> **Note**
>
> The `PIDS` column contains the number of processes and kernel threads created
> by that container. Threads is the term used by Linux kernel. Other equivalent
> terms are "lightweight process" or "kernel task", etc. A large number in the
> `PIDS` column combined with a small number of processes (as reported by `ps`
> or `top`) may indicate that something in the container is creating many threads.
## Examples
Running `docker stats` on all running containers against a Linux daemon.
```console
$ docker stats
CONTAINER ID NAME CPU % MEM USAGE / LIMIT MEM % NET I/O BLOCK I/O PIDS
b95a83497c91 awesome_brattain 0.28% 5.629MiB / 1.952GiB 0.28% 916B / 0B 147kB / 0B 9
67b2525d8ad1 foobar 0.00% 1.727MiB / 1.952GiB 0.09% 2.48kB / 0B 4.11MB / 0B 2

```
If you don't [specify a format string using `--format`](#formatting), the
following columns are shown.
| Column name | Description |
|---------------------------|-----------------------------------------------------------------------------------------------|
| `CONTAINER ID` and `Name` | the ID and name of the container |
| `CPU %` and `MEM %` | the percentage of the host's CPU and memory the container is using |
| `MEM USAGE / LIMIT` | the total memory the container is using, and the total amount of memory it is allowed to use |
| `NET I/O` | The amount of data the container has received and sent over its network interface |
| `BLOCK I/O` | The amount of data the container has written to and read from block devices on the host |
| `PIDs` | the number of processes or threads the container has created |
Running `docker stats` on multiple containers by name and id against a Linux daemon.
```console
$ docker stats awesome_brattain 67b2525d8ad1
CONTAINER ID NAME CPU % MEM USAGE / LIMIT MEM % NET I/O BLOCK I/O PIDS
b95a83497c91 awesome_brattain 0.28% 5.629MiB / 1.952GiB 0.28% 916B / 0B 147kB / 0B 9
67b2525d8ad1 foobar 0.00% 1.727MiB / 1.952GiB 0.09% 2.48kB / 0B 4.11MB / 0B 2
```
Running `docker stats` on container with name nginx and getting output in `json` format.
```console
$ docker stats nginx --no-stream --format "{{ json . }}"
{"BlockIO":"0B / 13.3kB","CPUPerc":"0.03%","Container":"nginx","ID":"ed37317fbf42","MemPerc":"0.24%","MemUsage":"2.352MiB / 982.5MiB","Name":"nginx","NetIO":"539kB / 606kB","PIDs":"2"}
```
Running `docker stats` with customized format on all (Running and Stopped) containers.
```console
$ 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:
```console
$ 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:
```console
$ 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}}"
