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!
