# cgxget(1)

print parameter(s) of given group(s)

## NAME

cgxget - print parameter(s) of given group(s)

## SYNOPSIS

**cgxget** \[**-1**\] \[**-2**\] \[**-i**\] \[**-n**\] \[**-v**\] \[**-b**\] \[**-r** \<*name*\>\] \[**-g** \<*controller*\>\] \[**-a**\] \<**path**\> ...\
 **cgxget** \[**-1**\] \[**-2**\] \[**-i**\] \[**-n**\] \[**-v**\] \[**-b**\] \[**-r** \<*name*\>\] **-g** \<*controller*\>:\<**path**\> ...

## DESCRIPTION

Prints the parameter(s) of input cgroup(s). If neither controller nor variable are specified, the values of all possible variables are displayed. When the request's cgroup version differs from the system's cgroup version, **cgxget** will attempt to translate from one version to the other. If the request version and the system's version are the same, no translation is done and **cgxget** will behave like **cgget**. If no version is specified by the user (either \[**-1**\] or \[**-2**\]), the behavior is undefined.

- **\<path\>**

  is the name of the cgroup which should be read. This parameter can be used multiple times.

- **-1, --v1**

  data in/out of **cgxget** is in cgroup v1 format. In this mode, the user will provide values in cgroup v1 format and receive values in v1 format. format. If the system is running in cgroup v2 mode, libcgroup will convert the data as necessary

- **-2, --v2**

  data in/out of **cgxget** is in cgroup v2 format. In this mode, the user will provide values in cgroup v2 format and receive values in v2 format. If the system is running in cgroup v1 mode, libcgroup will convert the data as necessary

- **-a, --all**

  print the variables for all controllers which consist in the  given cgroup

- **-b**

  ignores the default systemd delegated hierarchy path and constructs the path of the control groups relative to the cgroup root hierarchy.

- **-g \<controller\>**

  defines controllers whose values should be displayed. This option can be used multiple times.

- **-g \<controller\>:\<path\>**

  defines control groups whose values should be displayed. This option can be used multiple times.

- **-h, --help**

  display help and exit

- **-i, --ignore-unmappable**

  ignore errors for values that cannot be converted from v1 to v2 or vice versa

- **-n**

  do not print headers, i.e. names of groups.

- **-r, --variable \<name\>**

  defines parameter to display. This option can be used multiple times.

- **-v, --values-only**

  print only values, not parameter names.

## EXAMPLES

```
$ cgxget -1 -r cpuset.cpus -r cpuset.mems first second
first:
cpuset.cpus=0-1
cpuset.mems=0
second:
cpuset.cpus=0
cpuset.mems=0
$ cgxget -1 -n -r cpuset.cpus -r cpuset.mems first second
cpuset.cpus=0-1
cpuset.mems=0
cpuset.cpus=0
cpuset.mems=0
$ cgxget -1 -nv -r cpuset.cpus -r cpuset.mems first second
0-1
0
0
0
$ cgxget -1 -n -g cpu /
cpu.rt_period_us=1000000
cpu.rt_runtime_us=950000
cpu.shares=1024
$ cgxget -2 -r cpu.max first
first:
cpu.max: max 100000
```

## ENVIRONMENT VARIABLES

- **CGROUP\_LOGLEVEL**

  controls verbosity of the tool. Allowed values are **DEBUG**, **INFO**, **WARNING** or **ERROR**.
