CGSNAPSHOT(1)                  libcgroup Manual                  CGSNAPSHOT(1)



NAME
       cgsnapshot - generate the configuration file for given controllers


SYNOPSIS
       cgsnapshot [-h] [-s] [-t] [-b file] [-w file] [-f output_file]  [controller] [...]


DESCRIPTION
       cgsnapshot generates the cgconfig compatible configuration file for the given controllers.  If no controller is
       set, then cgsnapshot shows all mounted hierarchies.  The output is in the same format as the cgconfig.conf con-
       figuration file.


       -b file
              Display  only  variables  from  the  blacklist.   The  default location of the blacklist is /etc/cgsnap-
              shot_blacklist.conf.  This list contains all variables which should be ignored by the cgsnapshot If  the
              variable is blacklisted, it will not be displayed.  If it is not present on the blacklist, the whitelist
              is checked.


       -h, --help
              display this help and exit


       -f, --file
              Redirect the output to output_file



       -s, --silent
              Ignore all warnings


       -t, --strict
              Do not display the variables which are not on the whitelist



       -w file
              Set the blacklist configuration file.  This list contains all variables which  should  be  displayed  by
              cgsnapshot  If  the  variable  is  not blacklisted, the whitelist is checked.  If the variable is on the
              whitelist, it is displayed by cgsnapshot If the variable is not on the whitelist, the variable  is  dis-
              played and a warning message is produced.  By default the whitelist is not used.

              The  warning  message can be omitted using the -s, --silent flag.  If the -t, --strict flag is used, the
              variable which is not on the whitelist is not displayed.
