cgclassify - move running task(s) to given cgroups
cgclassify [-g
<controllers>:<path>] [--sticky | --cancel-sticky]
<pidlist>
this command moves processes defined by the list of processes
(pidlist) to the given control 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 controllers list.
This flag can be used multiple times to define multiple pairs
of lists of controllers 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 automatically change both the specified pidlist and their child
tasks to the right cgroup based on /etc/cgrules.conf.
- CGROUP_LOGLEVEL
- controls verbosity of the tool. Allowed values are DEBUG,
INFO, WARNING or ERROR.

- 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).
