NAME

       cgclassify - move running task(s) to given cgroups

SYNOPSIS

       cgclassify [-b] [-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

       -b     ignores the default systemd delegated hierarchy path and constructs the path of the control groups
              relative to the cgroup root hierarchy.

       -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.

       -r     Replaces systemd scope's idle process with the first process of the list of process (pidlist).

       --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.

ENVIRONMENT VARIABLES

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

FILES

       /etc/cgrules.conf
              default libcgroup configuration file

       /etc/cgrules.d
              default libcgroup configuration files directory

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).
