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!
