man lvmsadc () - LVM system activity data collector
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.
DIAGNOSTICS
