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 pro- cess to the appropriate control group.

The list of rules is read during the daemon startup is are cached in the daemons 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 destina- tions.

-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 des- tinations.

-n|--nodaemon Dont 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 /etc/cgconfig.conf the default templates file /etc/cgconfig.d/ the default templates directory
