NAME
       xenwatchdogd - Xen hypercall based watchdog daemon

SYNOPSIS
       xenwatchdogd [ OPTIONS ]	<TIMEOUT> [ <SLEEP> ]

DESCRIPTION
       xenwatchdogd arms the Xen watchdog timer	to TIMEOUT every SLEEP
       seconds.	If the xenwatchdogd process dies or is delayed for more	than
       TIMEOUT seconds,	then Xen will take the on_watchdog action specified in
       the domain configuration	(see xl.cfg(5)). If xenwatchdogd is running in
       dom0, the whole system will reboot.

OPTIONS
       -h, --help
	   Display a help message.

       -F, --foreground
	   Run in the foreground. The default behaviour	is to daemonize.

       -x, --safe-exit
	   Disable watchdog on orderly exit. The default behaviour is to arm
	   the watchdog	to 300 seconds to allow	time for the domain to
	   shutdown.  See also the SIGNALS section.

       timeout
	   The number of seconds to arm	the Xen	watchdog timer.	This must be
	   set to a minimum of two.

       sleep
	   The number of seconds to sleep in between calls to arm the Xen
	   watchdog timer. This	must be	at least one second, and less than the
	   timeout value. If not specified, it defaults	to half	the timeout
	   value.

SIGNALS
       SIGUSR1 Will cause the program to disarm	the watchdog timer and exit,
       regardless of whether the --safe-exit option was	passed.
