DESCRIPTION

16       cgsnapshot generates the cgconfig compatible configuration file for the
17       given  controllers.  If no controller is set, then cgsnapshot shows all
18       mounted hierarchies.  The output is in the same format  as  the  cgcon‐
19       fig.conf configuration file.

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

48       -w file
49              Set  the  blacklist  configuration file.  This list contains all
50              variables which should be displayed by cgsnapshot If  the  vari‐
51              able is not blacklisted, the whitelist is checked.  If the vari‐
52              able is on the whitelist, it is displayed by cgsnapshot  If  the
53              variable  is not on the whitelist, the variable is displayed and
54              a warning message is produced.  By default the whitelist is  not
55              used.
56
57              The  warning message can be omitted using the -s, --silent flag.
58              If the -t, --strict flag is used, the variable which is  not  on
