NAME
       wd_keepalive - a simplified software watchdog daemon

SYNOPSIS
       wd_keepalive [-c filename|--config-file filename]

DESCRIPTION
       This  is	 a  simplified	version	 of the watchdog daemon. It only opens
       /dev/watchdog, and keeps writing to it often enough to keep the	kernel
       from  resetting, at least once per minute. Each write delays the reboot
       time another minute. After a minute of inactivity the watchdog hardware
       will cause a reset. In the case of the software watchdog the ability to
       reboot will depend on the state of the machines and interrupts.

       The wd_keepalive daemon can be stopped without causing a reboot if  the
       device  /dev/watchdog  is  closed correctly, unless your kernel is com‐
       piled with the CONFIG_WATCHDOG_NOWAYOUT option enabled.

OPTIONS
       Available command line options are the following:

       -c config-file, --config-file config-file
	      Use config-file as the configuration file instead of the default
	      /etc/watchdog.conf.

FILES
       /dev/watchdog
	      The watchdog device.

       /var/run/wd_keepalive.pid
	      The pid file of the running wd_keepalive.
