# 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 want 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 page 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 page cache so that clients can use the data as needed.

> **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.

```bash
$ docker stats

CONTAINER ID        NAME                                    CPU %               MEM USAGE / LIMIT     MEM %               NET I/O             BLOCK I/O           PIDS

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 sent and received over its network interface             |
| `BLOCK I/O`               | The amount of data the container has read to and written 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.

```bash
$ 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` 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.

### 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,
> instead of `{{.ID}}\t{{.Name}}`.
