## 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 **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 ig‐
              nored 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 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


## ENVIRONMENT VARIABLES
       **CGROUP_LOGLEVEL**
              controls verbosity of the tool. Allowed values are **DEBUG**, **INFO**, **WARNING **or **ERROR**.
