CGCLASSIFY(1) libcgroup Manual CGCLASSIFY(1)
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 control groups.
The pids in the pidlist are separated by spaces
-g <controllers>:<path>
defines the control groups where the task will be moved. con-
trollers 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.
