## 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: Rootless environments 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 |
|
|
| .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 |
|
|
|
|
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.
|
|
|
|
@@option latest
|
|
|
|
@@option no-reset
|
|
|
|
@@option no-stream
|
|
|
|
#### **--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.
