WD_KEEPALIVE(8)WD_KEEPALIVE(8)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.
