Ubuntu Manpage: cgxget - 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
