cgsnapshot - generate the configuration file for given
controllers
cgsnapshot [-h] [-s] [-t] [-b
file] [-w file] [-f output_file]
[controller] [...]
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 configuration file.
- -b file
- Display only variables from the denylist. The default location of the
denylist is /etc/cgsnapshot_denylist.conf. This list contains all
variables which should be ignored by the cgsnapshot If the variable
is denylisted, it will not be displayed. If it is not present on the
denylist, the allowlist 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 allowlist
- -w file
- Set the denylist configuration file. This list contains all variables
which should be displayed by cgsnapshot If the variable is not
denylisted, the allowlist is checked. If the variable is on the allowlist,
it is displayed by cgsnapshot If the variable is not on the
allowlist, the variable is displayed and a warning message is produced. By
default the allowlist 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 allowlist is not displayed.
