       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 "Log-
       FilePath" 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

       -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
