lvmsadc(8)
NAME
lvmsadc - LVM system activity data collector
SYNOPSIS
lvmsadc [-d|--debug] [-h|--help] [-v|--verbose] [Log_ FilePath]
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 statis
tics 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
