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 |
| .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 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

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.
