     3  ## NAME
     4  podman\-stats - Display a live stream of one or more container's resource usage statistics
     5  
     6  ## SYNOPSIS
     7  **podman stats** [*options*] [*container*]
     8  
     9  **podman container stats** [*options*] [*container*]
    10  
    11  ## DESCRIPTION
    12  Display a live stream of one or more containers' resource usage statistics
    13  
    14  Note:  Podman stats will not work in rootless environments that use CGroups V1.
    15  Podman stats relies on CGroup information for statistics, and CGroup v1 is not
    16  supported for rootless use cases.
    17  
    18  Note: Rootless environments that use CGroups V2 are not able to report statistics
    19  about their networking usage.
    20  
    21  ## OPTIONS
    22  
    23  #### **--all**, **-a**
    24  
    25  Show all containers.  Only running containers are shown by default
    26  
    27  #### **--format**=*template*
    28  
    29  Pretty-print container statistics to JSON or using a Go template
    30  
    31  Valid placeholders for the Go template are listed below:
    32  
    33  | **Placeholder** | **Description**    |
    34  | --------------- | ------------------ |
    35  | .ID             | Container ID       |
    36  | .Name           | Container Name     |
    37  | .CPUPerc        | CPU percentage     |
    38  | .MemUsage       | Memory usage       |
    39  | .MemUsageBytes  | Memory usage (IEC) |
    40  | .MemPerc        | Memory percentage  |
    41  | .NetIO          | Network IO         |
    42  | .BlockIO        | Block IO           |
    43  | .PIDS           | Number of PIDs     |
    44  
    45  When using a GO template, you may precede the format with `table` to print headers.
    46  
    47  #### **--interval**=*seconds*, **-i**=*seconds*
    48  
    49  Time in seconds between stats reports, defaults to 5 seconds.
    50  
    51  #### **--latest**, **-l**
    52  
    53  Instead of providing the container name or ID, use the last created container. If you use methods other than Podman
    54  to run containers such as CRI-O, the last started container could be from either of those methods. (This option is not available with the remote Podman client, including Mac and Windows (excluding WSL2) machines)
    55  
    56  #### **--no-reset**
    57  
    58  Do not clear the terminal/screen in between reporting intervals
    59  
    60  #### **--no-stream**
    61  
    62  Disable streaming stats and only pull the first result, default setting is false
    63  
    64  ## EXAMPLE
    65  
    66  ```
    67  # podman stats -a --no-stream
    68  ID             NAME              CPU %   MEM USAGE / LIMIT   MEM %   NET IO    BLOCK IO   PIDS
    69  a9f807ffaacd   frosty_hodgkin    --      3.092MB / 16.7GB    0.02%   -- / --   -- / --    2
    70  3b33001239ee   sleepy_stallman   --      -- / --             --      -- / --   -- / --    --
    71  ```
    72  
    73  ```
    74  # podman stats --no-stream a9f80
    75  ID             NAME             CPU %   MEM USAGE / LIMIT   MEM %   NET IO    BLOCK IO   PIDS
    76  a9f807ffaacd   frosty_hodgkin   --      3.092MB / 16.7GB    0.02%   -- / --   -- / --    2
    77  ```
    78  
    79  ```
    80  # podman stats --no-stream --format=json a9f80
    81  [
    82      {
    83  	"id": "a9f807ffaacd",
    84  	"name": "frosty_hodgkin",
    85  	"cpu_percent": "--",
    86  	"mem_usage": "3.092MB / 16.7GB",
    87  	"mem_percent": "0.02%",
    88  	"netio": "-- / --",
    89  	"blocki": "-- / --",
    90  	"pids": "2"
    91      }
    92  ]
    93  ```
    94  
    95  ```
    96  # podman stats --no-stream --format "table {{.ID}} {{.Name}} {{.MemUsage}}" 6eae
    97  ID             NAME           MEM USAGE / LIMIT
    98  6eae9e25a564   clever_bassi   3.031MB / 16.7GB
    99  ```
   100  
   101  Note: When using a slirp4netns network with the rootlesskit port
   102  handler, the traffic send via the port forwarding will be accounted to
   103  the `lo` device.  Traffic accounted to `lo` is not accounted in the
   104  stats output.
