       lvmsadc - LVM system activity data collector


       lvmsadc [-d|--debug] [-h|--help] [-v|--verbose] [LogFilePath]


       lvmsadc  collects  the  read/write  statistics  of  the  logical volume
       manager to the file "LogFilePath" or to stdout  if  no  LogFilePath  is
       given.   If  you  want  to  have I/O statistics at hand for performance
       tuning, you should create a cron entry for lvmsadc  which  runs  it  at
       regular intervals eg. 10 minutes. You need to take care of size control
       of the log file yourself!

       -d, --debug
              Enables additional debugging output (if compiled with DEBUG).

       -h, --help
              Print a usage message on standard output and exit  successfully.

       -v, --verbose
              Gives verbose runtime information about lvmsadc’s activities.


       lvmsadc returns an exit code of 0 for success or > 0 for error:

       1  no log file path and name on command line
       2  error opening log file for append
       3  no volume groups found for data collection
       4  error closing log file

       95 driver/module not in kernel
       96 invalid I/O protocol version
       97 error locking logical volume manager
       98 invalid lvmtab (run vgscan(8))
       99 invalid command line
