LVMSADC(8)

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
