hwmond(8)                                BSD System Manager's Manual                               hwmond(8)

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 plat-form platform
     form running Mac OS X Server.  hwmond runs in the background periodically collecting various informa-tion information
     tion 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 infor-mation information
     mation 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 main-tained maintained
     tained in memory.  This dictionary is retrieved by the servermgr_xserve plugin that is part of the
     server manager 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 storage 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.
