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

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))
