NAME
       lvmsadc - LVM system activity data collector

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

DESCRIPTION
       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!

   OPTIONS
       -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.
