--- title: "stats" description: "The stats command description and usage" keywords: "container, resource, statistics" --- # 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. ## 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 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 e5c383697914 test-1951.1.kay7x1lh1twk9c0oig50sd5tr 0.00% 196KiB / 1.952GiB 0.01% 71.2kB / 0B 770kB / 0B 1 4bda148efbc0 random.1.vnc8on831idyr42slu578u3cr 0.00% 1.672MiB / 1.952GiB 0.08% 110kB / 0B 578kB / 0B 2 ``` 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. Running `docker stats` on all running containers against a Windows daemon. ```powershell PS E:\> docker stats CONTAINER ID CPU % PRIV WORKING SET NET I/O BLOCK I/O 09d3bb5b1604 6.61% 38.21 MiB 17.1 kB / 7.73 kB 10.7 MB / 3.57 MB 9db7aa4d986d 9.19% 38.26 MiB 15.2 kB / 7.65 kB 10.6 MB / 3.3 MB 3f214c61ad1d 0.00% 28.64 MiB 64 kB / 6.84 kB 4.42 MB / 6.93 MB ``` Running `docker stats` on multiple containers by name and id against a Windows daemon. ```powershell PS E:\> docker ps -a CONTAINER ID NAME IMAGE COMMAND CREATED STATUS PORTS NAMES 3f214c61ad1d awesome_brattain nanoserver "cmd" 2 minutes ago Up 2 minutes big_minsky 9db7aa4d986d mad_wilson windowsservercore "cmd" 2 minutes ago Up 2 minutes mad_wilson 09d3bb5b1604 fervent_panini windowsservercore "cmd" 2 minutes ago Up 2 minutes affectionate_easley PS E:\> docker stats 3f214c61ad1d mad_wilson CONTAINER ID NAME CPU % PRIV WORKING SET NET I/O BLOCK I/O 3f214c61ad1d awesome_brattain 0.00% 46.25 MiB 76.3 kB / 7.92 kB 10.3 MB / 14.7 MB 9db7aa4d986d mad_wilson 9.59% 40.09 MiB 27.6 kB / 8.81 kB 17 MB / 20.1 MB ``` ### 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}}`.
