NAME cgsnapshot - generate the configuration file for given controllers

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

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 cgcon- fig.conf configuration file.

-b file Display only variables from the blacklist. The default location of the blacklist is /etc/cgsnapshot_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 vari- able is not blacklisted, the whitelist is checked. If the vari- able is on the whitelist, it is displayed by cgsnapshot If the variable is not on the whitelist, the variable is displayed 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.

controller defines the controller whose hierarchies will be output
