podman-stats(1)             General Commands Manual            podman-stats(1)

NAME
       podman-stats - Display a live stream of one or more container's
       resource usage statistics


SYNOPSIS
       podman stats [options] [container]


       podman container stats [options] [container]


DESCRIPTION
       Display a live stream of one or more containers' resource usage
       statistics


       Note:  Podman stats does not work in rootless environments that use
       CGroups V1.  Podman stats relies on CGroup information for statistics,
       and CGroup v1 is not supported for rootless use cases.


       Note: Rootless environments that use CGroups V2 are not able to report
       statistics about their networking usage.


OPTIONS
   --all, -a
       Show all containers.  Only running containers are shown by default


   --format=template
       Pretty-print container statistics to JSON or using a Go template


       Valid placeholders for the Go template are listed below:

       [1] Cgroups V1 only


       When using a Go template, precede the format with table to print
       headers.


   --interval, -i=seconds
       Time in seconds between stats reports, defaults to 5 seconds.


   --latest, -l
       Instead of providing the container name or ID, use the last created
       container.  Note: the last started container can be from other users of
       Podman on the host machine.  (This option is not available with the
       remote Podman client, including Mac and Windows (excluding WSL2)
       machines)


   --no-reset
       Do not clear the terminal/screen in between reporting intervals


   --no-stream
       Disable streaming stats and only pull the first result, default setting
       is false


   --no-trunc
       Do not truncate output


EXAMPLE
       List statistics about all running containers without streaming mode:

       # podman stats -a --no-stream
       ID             NAME              CPU %   MEM USAGE / LIMIT   MEM %   NET IO    BLOCK IO   PIDS
       a9f807ffaacd   frosty_hodgkin    --      3.092MB / 16.7GB    0.02%   -- / --   -- / --    2
       3b33001239ee   sleepy_stallman   --      -- / --             --      -- / --   -- / --    --



       List the specified container's statistics in streaming mode:

       # podman stats a9f80
       ID             NAME             CPU %   MEM USAGE / LIMIT   MEM %   NET IO    BLOCK IO   PIDS
       a9f807ffaacd   frosty_hodgkin   --      3.092MB / 16.7GB    0.02%   -- / --   -- / --    2



       List the specified statistics about the specified container in table
       format:

       $ podman stats --no-trunc 3667 --format 'table {{ .ID }} {{ .MemUsage }}'
       ID                                                                MEM USAGE / LIMIT
       3667c6aacb06aac2eaffce914c01736420023d56ef9b0f4cfe58b6d6a78b7503  49.15kB / 67.17GB



       List the specified container statistics in JSON format:

       # podman stats --no-stream --format=json a9f80
       [
           {
            "id": "a9f807ffaacd",
            "name": "frosty_hodgkin",
            "cpu_percent": "--",
            "mem_usage": "3.092MB / 16.7GB",
            "mem_percent": "0.02%",
            "netio": "-- / --",
            "blocki": "-- / --",
            "pids": "2"
           }
       ]



       List the specified container statistics in table format:

       # podman stats --no-stream --format "table {{.ID}} {{.Name}} {{.MemUsage}}" 6eae
       ID             NAME           MEM USAGE / LIMIT
       6eae9e25a564   clever_bassi   3.031MB / 16.7GB



       Note: When using a slirp4netns network with the rootlesskit port
       handler, the traffic sent via the port forwarding is accounted to the
       lo device.  Traffic accounted to lo is not accounted in the stats
       output.
