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:
Placeholder | Description
.AvgCPU | Average CPU, full precision float
.AVGCPU | Average CPU, formatted as a percent
.BlockInput | Total data read from block device
.BlockIO | Total data read/total data written to block device
.BlockOutput | Total data written to block device
.ContainerID | Container ID, full (untruncated) hash
.ContainerStats ... | Nested structure, for experts only
.CPU | Percent CPU, full precision float
.CPUNano | CPU Usage, total, in nanoseconds
.CPUPerc | Percentage of CPU used
.CPUSystemNano | CPU Usage, kernel, in nanoseconds
.Duration | Same as CPUNano
.ID | Container ID, truncated
.MemLimit | Memory limit, in bytes
.MemPerc | Memory percentage used
.MemUsage | Memory usage
.MemUsageBytes | Memory usage (IEC)
.Name | Container Name
.NetIO | Network IO
.Network ... | Network I/O, separated by network interface
.PerCPU | CPU time consumed by all tasks [1]
.PIDs | Number of PIDs
.PIDS | Number of PIDs (yes, we know this is a dup)
.SystemNano | Current system datetime, nanoseconds since epoch
.Up | Duration (CPUNano), in human-readable form
.UpTime | Same as Up

[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.
