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. 34 35 If you want more detailed information about a container's resource usage, use the `/containers/(id)/stats` API endpoint. 36 37 > **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. 38 39 ## Examples 40 41 Running `docker stats` on all running containers against a Linux daemon. 42 43 ```bash 44 $ docker stats 45 46 CONTAINER ID NAME CPU % MEM USAGE / LIMIT MEM % NET I/O BLOCK I/O PIDS 47 b95a83497c91 awesome_brattain 0.28% 5.629MiB / 1.952GiB 0.28% 916B / 0B 147kB / 0B 9 48 67b2525d8ad1 foobar 0.00% 1.727MiB / 1.952GiB 0.09% 2.48kB / 0B 4.11MB / 0B 2 49 e5c383697914 test-1951.1.kay7x1lh1twk9c0oig50sd5tr 0.00% 196KiB / 1.952GiB 0.01% 71.2kB / 0B 770kB / 0B 1 50 4bda148efbc0 random.1.vnc8on831idyr42slu578u3cr 0.00% 1.672MiB / 1.952GiB 0.08% 110kB / 0B 578kB / 0B 2 51 ``` 52 53 Running `docker stats` on multiple containers by name and id against a Linux daemon. 54 55 ```bash 56 $ docker stats awesome_brattain 67b2525d8ad1 57 58 CONTAINER ID NAME CPU % MEM USAGE / LIMIT MEM % NET I/O BLOCK I/O PIDS 59 b95a83497c91 awesome_brattain 0.28% 5.629MiB / 1.952GiB 0.28% 916B / 0B 147kB / 0B 9 60 67b2525d8ad1 foobar 0.00% 1.727MiB / 1.952GiB 0.09% 2.48kB / 0B 4.11MB / 0B 2 61 ``` 62 63 Running `docker stats` with customized format on all (Running and Stopped) containers. 64 65 ```bash 66 $ docker stats --all --format "table {{.Container}}\t{{.CPUPerc}}\t{{.MemUsage}}" fervent_panini 5acfcb1b4fd1 drunk_visvesvaraya big_heisenberg 67 68 CONTAINER CPU % MEM USAGE / LIMIT 69 fervent_panini 0.00% 56KiB / 15.57GiB 70 5acfcb1b4fd1 0.07% 32.86MiB / 15.57GiB 71 drunk_visvesvaraya 0.00% 0B / 0B 72 big_heisenberg 0.00% 0B / 0B 73 ``` 74 75 `drunk_visvesvaraya` and `big_heisenberg` are stopped containers in the above example. 76 77 Running `docker stats` on all running containers against a Windows daemon. 78 79 ```powershell 80 PS E:\> docker stats 81 CONTAINER ID CPU % PRIV WORKING SET NET I/O BLOCK I/O 82 09d3bb5b1604 6.61% 38.21 MiB 17.1 kB / 7.73 kB 10.7 MB / 3.57 MB 83 9db7aa4d986d 9.19% 38.26 MiB 15.2 kB / 7.65 kB 10.6 MB / 3.3 MB 84 3f214c61ad1d 0.00% 28.64 MiB 64 kB / 6.84 kB 4.42 MB / 6.93 MB 85 ``` 86 87 Running `docker stats` on multiple containers by name and id against a Windows daemon. 88 89 ```powershell 90 PS E:\> docker ps -a 91 CONTAINER ID NAME IMAGE COMMAND CREATED STATUS PORTS NAMES 92 3f214c61ad1d awesome_brattain nanoserver "cmd" 2 minutes ago Up 2 minutes big_minsky 93 9db7aa4d986d mad_wilson windowsservercore "cmd" 2 minutes ago Up 2 minutes mad_wilson 94 09d3bb5b1604 fervent_panini windowsservercore "cmd" 2 minutes ago Up 2 minutes affectionate_easley 95 96 PS E:\> docker stats 3f214c61ad1d mad_wilson 97 CONTAINER ID NAME CPU % PRIV WORKING SET NET I/O BLOCK I/O 98 3f214c61ad1d awesome_brattain 0.00% 46.25 MiB 76.3 kB / 7.92 kB 10.3 MB / 14.7 MB 99 9db7aa4d986d mad_wilson 9.59% 40.09 MiB 27.6 kB / 8.81 kB 17 MB / 20.1 MB 100 ``` 101 102 ### Formatting 103 104 The formatting option (`--format`) pretty prints container output 105 using a Go template. 106 107 Valid placeholders for the Go template are listed below: 108 109 Placeholder | Description 110 ------------ | -------------------------------------------- 111 `.Container` | Container name or ID (user input) 112 `.Name` | Container name 113 `.ID` | Container ID 114 `.CPUPerc` | CPU percentage 115 `.MemUsage` | Memory usage 116 `.NetIO` | Network IO 117 `.BlockIO` | Block IO 118 `.MemPerc` | Memory percentage (Not available on Windows) 119 `.PIDs` | Number of PIDs (Not available on Windows) 120 121 122 When using the `--format` option, the `stats` command either 123 outputs the data exactly as the template declares or, when using the 124 `table` directive, includes column headers as well. 125 126 The following example uses a template without headers and outputs the 127 `Container` and `CPUPerc` entries separated by a colon for all images: 128 129 ```bash 130 $ docker stats --format "{{.Container}}: {{.CPUPerc}}" 131 132 09d3bb5b1604: 6.61% 133 9db7aa4d986d: 9.19% 134 3f214c61ad1d: 0.00% 135 ``` 136 137 To list all containers statistics with their name, CPU percentage and memory 138 usage in a table format you can use: 139 140 ```bash 141 $ docker stats --format "table {{.Container}}\t{{.CPUPerc}}\t{{.MemUsage}}" 142 143 CONTAINER CPU % PRIV WORKING SET 144 1285939c1fd3 0.07% 796 KiB / 64 MiB 145 9c76f7834ae2 0.07% 2.746 MiB / 64 MiB 146 d1ea048f04e4 0.03% 4.583 MiB / 64 MiB 147 ``` 148 149 The default format is as follows: 150 151 On Linux: 152 153 "table {{.ID}}\t{{.Name}}\t{{.CPUPerc}}\t{{.MemUsage}}\t{{.MemPerc}}\t{{.NetIO}}\t{{.BlockIO}}\t{{.PIDs}}" 154 155 On Windows: 156 157 "table {{.ID}}\t{{.Name}}\t{{.CPUPerc}}\t{{.MemUsage}}\t{{.NetIO}}\t{{.BlockIO}}" 158 159 160 > **Note**: On Docker 17.09 and older, the `{{.Container}}` column was used, in 161 > stead of `{{.ID}}\t{{.Name}}`.
