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).
