NAME

       cgrulesengd - control group rules daemon

SYNOPSIS

       cgrulesengd [options]

DESCRIPTION

       cgrulesengd  is	a  daemon,  which  distributes processes to control groups. When any process changes its effective UID or GID, cgrulesengd
       inspects the list of rules loaded from the cgrules.conf file and moves the process to the appropriate control group.

       The list of rules is read during the daemon startup is are cached in the daemon's memory.  The daemon reloads the list  of  rules  when	it
       receives SIGUSR2 signal.

       The daemon opens a standard unix socket to receive 'sticky' requests from cgexec.

OPTIONS

       -h|--help
	      Display help.

       -f <path>|--logfile=<path>
	      Write  log  messages to the given log file. When '-' is used as <path>, log messages are written to the standard output. If '-f' and
	      '-s' are used together, the logs are sent to both destinations.

       -s[facility]|--syslog=[facility]
	      Write log messages to syslog. The default facility is DAEMON. If '-f' and '-s' are used together, the logs are sent to both destina-
	      tions.

       -n|--nodaemon
	      Don't fork the daemon, stay in the foreground.

       -v|--verbose
	      Display more log messages. This option can be used twice to enable more verbose log messages.

       -q|--quiet
	      Display less log messages. This option can be used twice to enable even less log messages and to only log errors.

       -Q|--nolog
	      Disable logging.

       -d|--debug
	      Equivalent to '-nvvf -', i.e. don't fork the daemon, display all log messages and write them to the standard output.

       -u <user>|--socket-user=<user>
	      -g  <group>|--socket-group=<group>  Set the owner of cgrulesengd socket. Assumes that cgexec runs with proper suid permissions so it
	      can write to the socket when cgexec --sticky is used.

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.	controllers is a list of controllers and path is the relative path to con-
	      trol 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 chil-
	      dren 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
