     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  #### **--latest**, **-l**
    28  
    29  Instead of providing the container name or ID, use the last created container. If you use methods other than Podman
    30  to run containers such as CRI-O, the last started container could be from either of those methods.
    31  
    32  The latest option is not supported on the remote client.
    33  
    34  #### **--no-reset**
    35  
    36  Do not clear the terminal/screen in between reporting intervals
    37  
    38  #### **--no-stream**
    39  
    40  Disable streaming stats and only pull the first result, default setting is false
    41  
    42  #### **--format**=*template*
    43  
    44  Pretty-print container statistics to JSON or using a Go template
    45  
    46  Valid placeholders for the Go template are listed below:
    47  
    48  | **Placeholder** | **Description**   |
    49  | --------------- | ---------------   |
    50  | .ID             | Container ID      |
    51  | .Name           | Container Name    |
    52  | .CPUPerc        | CPU percentage    |
    53  | .MemUsage       | Memory usage      |
    54  | .MemPerc        | Memory percentage |
    55  | .NetIO          | Network IO        |
    56  | .BlockIO        | Block IO          |
    57  | .PIDS           | Number of PIDs    |
    58  
    59  When using a GO template, you may precede the format with `table` to print headers.
