NAME
hwmond -- Mac OS X Server Hardware monitoring daemon
SYNOPSIS
hwmond [ -h | -t ] [ -s seconds ]
DESCRIPTION
hwmond is short for HardWare MONitoring Daemon which, in its current
form, executes on the Xserve platform running Mac OS X Server. hwmond
runs in the background periodically collecting various information about
the current state of the hardware.
OPTIONS
The following options are available:
-h Print usage summary and exit.
-s Specify the number of seconds for polling period (polled info).
-t Determine if we run on this machine and exit. (TRUE/FALSE)
USAGE
In typical usage, hwmond is launched during the boot process by the
launchd(8) user-daemon. Upon launch, hwmond moves to the background,
reads its configuration file and waits to be activated by a timer setup
to fire at a predetermined, or -s, number of seconds. hwmond will then
log relevant information in the file var/log/hwmond.log, and optionally
send an email using sendmail.
The information currently collected by hwmond is parsed, organized and
stored in a CFDictionary maintained in memory. This dictionary is
retrieved by the servermgr_xserve plugin that is part of the server man-
ager architechure.
hwmond is most useful when used in conjuction with the "Server Monitor"
application. This application provides a GUI to display the retrieved
CFDictionary and is also used to configure the hwmond file
/etc/hwmond.conf.
Finally, the hand-edited plist /etc/hwmond.SMART contains a list of stor-
age devices and resulting SMART errors that hwmond will log and report.
If a particular storage device is not listed in this file, generic SMART
errors will be logged.
