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 statis-
       tics

       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 head-
       ers.

   --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 con-
       tainer.  Note: the last started container can be  from  other  users  of
       Podman  on the host machine.  (This option is not available with the re-
       mote 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  han-
       dler,  the  traffic  sent via the port forwarding is accounted to the lo
       device.  Traffic accounted to lo is not accounted in the stats output.
