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 will 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

Block Input

.BlockIO

Block IO

.BlockOutput

Block Output

.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

CPU percentage

.CPUSystemNano

CPU Usage, kernel, in nanoseconds

.Duration

Same as CPUNano

.ID

Container ID, truncated

.MemLimit

Memory limit, in bytes

.MemPerc

Memory percentage

.MemUsage

Memory usage

.MemUsageBytes

Memory usage (IEC)

.Name

Container Name

.NetInput

Network Input

.NetIO

Network IO

.NetOutput

Network Output

.PerCPU

CPU time consumed by all tasks [1]

.PIDs

Number of PIDs

.PIDS

Number of PIDs (yes, we know it’s a dup)

.SystemNano

Current system datetime, nanoseconds since epoch

.Up

Duration (CPUNano), in human-readable form

.UpTime

Same as UpTime

[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 could 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

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