NAME

       cgexec - run the task in given control groups

SYNOPSIS

       cgexec [-h] [-g <controllers>:<path>] [--sticky] command [arguments]

DESCRIPTION

       The cgexec program executes the task command with arguments arguments in the given control groups.

       -g <controllers>:<path>
	      defines  the  control  groups  in which the task will be run.  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 b"*b" can be used.

	      If this option is not used, cgexec will automatically place the task in the right cgroup based on /etc/cgrules.conf.

	      If  /etc/cgrules.conf  configuration file is used, there can be used template names. Then the control group name contains a template
	      in destination tag (see cgrules.conf (5)) and if the cgroup does not exist in execution time, it is created,  based  on  /etc/cgcon-
	      fig.conf specification.  If the specifications are not present the group is created with the default kernel values.

       -h, --help
	      Display this help and exit.

       --sticky
	      If running the task command with this option, the daemon of service cgred (cgrulesengd process) does not change both the task of the
	      command and the child tasks. Without this option, the daemon does not change the task of the command but it changes the child  tasks
	      to the right cgroup based on /etc/cgrules.conf automatically.

EXAMPLES

       cgexec -g *:test1 ls
       runs command ls in control group test1 in all mounted controllers.

       cgexec -g cpu,memory:test1 ls -l
       runs command ls -l in control group test1 in controllers cpu and memory.

       cgexec -g cpu,memory:test1 -g swap:test2 ls -l
       runs command ls -l in control group test1 in controllers cpu and memory and control group test2 in controller swap.

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 reloads the list of templates when it receives SIGUSR1 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 three times to enable more verbose log messages.

       -q|--quiet
	      Display less log messages.

       -Q|--nolog
	      Disable logging.

       -d|--debug
	      Equivalent to '-nvvvf -', 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.

ENVIRONMENT VARIABLES

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

FILES

       /etc/cgrules.conf
       the default libcgroup configuration file
