NAME

       cgcreate - create new cgroup(s)

SYNOPSIS

       cgcreate [-h] [-t <tuid>:<tgid>] [-a <agid>:<auid>] [-f mode] [-d mode] [-s mode] -g <controllers>:<path> [-g ...]

DESCRIPTION

       The command creates new cgroup(s) defined by the options -g.

       -a <agid>:<auid>
	      defines  the  name of the user and the group which own the rest of the defined control group's files. These users are allowed to set
	      subsystem parameters and create subgroups.  The default value is the same as has the parent cgroup.

       -d, --dperm=mode
	      sets the permissions of a control groups directory.  The permissions needs to be specified as octal numbers e.g.	-d 775.

       -f, --fperm=mode
	      sets the permissions of the control groups parameters.  The permissions needs to be specified as octal numbers e.g.   -f	775.   The
	      value  is  not  used as given because the current owner's permissions are used as an umask (so 777 will set group and others permis-
	      sions to the owners permissions).

       -g <controllers>:<path>
	      defines control groups to be added.  controllers is a list of controllers and path is the relative path to  control  groups  in  the
	      given controllers list. This option can be specified multiple times.

       -h, --help
	      display this help and exit

       -s, --tperm=mode
	      sets  the  permissions  of  the control group tasks file.  The permissions needs to be specified as octal numbers e.g.  -s 775.  The
	      value is not used as given because the current owner's permissions are used as an umask (so 777 will set group  and  others  permis-
	      sions to the owners permissions).

       -t <tuid>:<tgid>
	      defines  the  name of the user and the group, which owns tasks file of the defined control group. I.e. this user and members of this
	      group have write access to the file.  The default value is the same as has the parent cgroup.

ENVIRONMENT VARIABLES

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

NAME

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

SYNOPSIS

       cgget [-n] [-v] [-r <name>] [-g <controller>] [-a] <path> ...
       cgget [-n] [-v] [-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.

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

       -a, --all
	      print the variables for all controllers which consist in the  given cgroup

       -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

       -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

       $ cgget -r cpuset.cpus -r cpuset.mems first second
       first:
       cpuset.cpus=0-1
       cpuset.mems=0

       second:
       cpuset.cpus=0
       cpuset.mems=0

       $ cgget -n -r cpuset.cpus -r cpuset.mems first second
       cpuset.cpus=0-1
       cpuset.mems=0
       cpuset.cpus=0
       cpuset.mems=0

       $ cgget -nv -r cpuset.cpus -r cpuset.mems first second
       0-1
       0
       0
       0

       $ cgget -n -g cpu /
       cpu.rt_period_us=1000000
       cpu.rt_runtime_us=950000
