NAME
cgclassify - move running task(s) to given cgroups

SYNOPSIS
cgclassify [-g <controllers>:<path>] [--sticky | --cancel-sticky] <pidlist>

DESCRIPTION
this command moves processes defined by the list of processes (pidlist) to the given con-
trol groups.

The pids in the pidlist are separated by spaces

-g <controllers>:<path>
defines the control groups where the task will be moved. controllers is a list of
controllers and path is the relative path to control groups in the given con-
trollers list.

This flag can be used multiple times to define multiple pairs of lists of con-
trollers and relative paths. Instead of the list of all mounted controllers, the
wildcard * can be used.

If this option is not used then cgclassify will automatically move the task to a
control group based on /etc/cgrules.conf.

--sticky
If this option is used, the daemon of service cgred (cgrulesengd process) does not
change both the specified pidlist and their children tasks. Without this option,
the daemon does not change the specified pidlist but it automatically changes their
child tasks to the right cgroup based on /etc/cgrules.conf.

--cancel-sticky
If this option is used, the daemon of service cgred (cgrulesengd process) can auto-
matically change both the specified pidlist and their child tasks to the right
cgroup based on /etc/cgrules.conf.

EXAMPLES
cgclassify -g cpu:student 1234
moves process with pid number 1234 to control group student in cpu hierarchy.

cgclassify 1234
moves process with pid number 1234 to control groups based on /etc/cgrules.conf
configuration file.

cgclassify --sticky -g cpu:/student 1234
moves process with pid number 1234 to control group student in cpu hierarchy. The
daemon of service cgred does not change cgroups of pid 1234 and its children (based
on /etc/cgrules.conf).
