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. 30 31 If you want more detailed information about a container's resource usage, use the `/containers/(id)/stats` API endpoint. 32 33 ## Examples 34 35 Running `docker stats` on all running containers against a Linux daemon. 36 37 $ docker stats 38 CONTAINER CPU % MEM USAGE / LIMIT MEM % NET I/O BLOCK I/O 39 1285939c1fd3 0.07% 796 KiB / 64 MiB 1.21% 788 B / 648 B 3.568 MB / 512 KB 40 9c76f7834ae2 0.07% 2.746 MiB / 64 MiB 4.29% 1.266 KB / 648 B 12.4 MB / 0 B 41 d1ea048f04e4 0.03% 4.583 MiB / 64 MiB 6.30% 2.854 KB / 648 B 27.7 MB / 0 B 42 43 Running `docker stats` on multiple containers by name and id against a Linux daemon. 44 45 $ docker stats fervent_panini 5acfcb1b4fd1 46 CONTAINER CPU % MEM USAGE/LIMIT MEM % NET I/O 47 5acfcb1b4fd1 0.00% 115.2 MiB/1.045 GiB 11.03% 1.422 kB/648 B 48 fervent_panini 0.02% 11.08 MiB/1.045 GiB 1.06% 648 B/648 B 49 50 Running `docker stats` on all running containers against a Windows daemon. 51 52 PS E:\> docker stats 53 CONTAINER CPU % PRIV WORKING SET NET I/O BLOCK I/O 54 09d3bb5b1604 6.61% 38.21 MiB 17.1 kB / 7.73 kB 10.7 MB / 3.57 MB 55 9db7aa4d986d 9.19% 38.26 MiB 15.2 kB / 7.65 kB 10.6 MB / 3.3 MB 56 3f214c61ad1d 0.00% 28.64 MiB 64 kB / 6.84 kB 4.42 MB / 6.93 MB 57 58 Running `docker stats` on multiple containers by name and id against a Windows daemon. 59 60 PS E:\> docker ps -a 61 CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 62 3f214c61ad1d nanoserver "cmd" 2 minutes ago Up 2 minutes big_minsky 63 9db7aa4d986d windowsservercore "cmd" 2 minutes ago Up 2 minutes mad_wilson 64 09d3bb5b1604 windowsservercore "cmd" 2 minutes ago Up 2 minutes affectionate_easley 65 66 PS E:\> docker stats 3f214c61ad1d mad_wilson 67 CONTAINER CPU % PRIV WORKING SET NET I/O BLOCK I/O 68 3f214c61ad1d 0.00% 46.25 MiB 76.3 kB / 7.92 kB 10.3 MB / 14.7 MB 69 mad_wilson 9.59% 40.09 MiB 27.6 kB / 8.81 kB 17 MB / 20.1 MB 70 71 ## Formatting 72 73 The formatting option (`--format`) pretty prints container output 74 using a Go template. 75 76 Valid placeholders for the Go template are listed below: 77 78 Placeholder | Description 79 ------------ | -------------------------------------------- 80 `.Container` | Container name or ID 81 `.CPUPerc` | CPU percentage 82 `.MemUsage` | Memory usage 83 `.NetIO` | Network IO 84 `.BlockIO` | Block IO 85 `.MemPerc` | Memory percentage (Not available on Windows) 86 `.PIDs` | Number of PIDs (Not available on Windows) 87 88 89 When using the `--format` option, the `stats` command either 90 outputs the data exactly as the template declares or, when using the 91 `table` directive, includes column headers as well. 92 93 The following example uses a template without headers and outputs the 94 `Container` and `CPUPerc` entries separated by a colon for all images: 95 96 ```bash 97 $ docker stats --format "{{.Container}}: {{.CPUPerc}}" 98 99 09d3bb5b1604: 6.61% 100 9db7aa4d986d: 9.19% 101 3f214c61ad1d: 0.00% 102 ``` 103 104 To list all containers statistics with their name, CPU percentage and memory 105 usage in a table format you can use: 106 107 ```bash 108 $ docker stats --format "table {{.Container}}\t{{.CPUPerc}}\t{{.MemUsage}}" 109 110 CONTAINER CPU % PRIV WORKING SET 111 1285939c1fd3 0.07% 796 KiB / 64 MiB 112 9c76f7834ae2 0.07% 2.746 MiB / 64 MiB 113 d1ea048f04e4 0.03% 4.583 MiB / 64 MiB 114 ```
