6 wd_keepalive - a simplified software watchdog daemon
7
9 wd_keepalive [-c filename|--config-file filename]
10
12 This is a simplified version of the watchdog daemon. It only opens
13 /dev/watchdog, and keeps writing to it often enough to keep the kernel
14 from resetting, at least once per minute. Each write delays the reboot
15 time another minute. After a minute of inactivity the watchdog hardware
16 will cause a reset. In the case of the software watchdog the ability to
17 reboot will depend on the state of the machines and interrupts.
18
19 The wd_keepalive daemon can be stopped without causing a reboot if the
20 device /dev/watchdog is closed correctly, unless your kernel is com‐
21 piled with the CONFIG_WATCHDOG_NOWAYOUT option enabled.
22
24 Available command line options are the following:
25
26 -c config-file, --config-file config-file
27 Use config-file as the configuration file instead of the default
28 /etc/watchdog.conf.
29
31 /dev/watchdog
32 The watchdog device.
33
34 /var/run/wd_keepalive.pid
35 The pid file of the running wd_keepalive.
