wd_keepalive: a simplified software watchdog daemon
wd_keepalive - a simplified software watchdog daemon
SYNOPSISwd_keepalive [-c filename|--config-file filename]
DESCRIPTIONThis is a simplified version of the watchdog daemon. If configured so it only opens
The wd_keepalive daemon can be stopped without causing a reboot if the device /dev/watchdog is closed correctly, unless your kernel is compiled with the CONFIG_WATCHDOG_NOWAYOUT option enabled.
Under high system load wd_keepalive might be swapped out of memory and may fail to make it back in in time. Under these circumstances the Linux kernel will reset the machine. To make sure you won't get unnecessary reboots make sure you have the variable realtime set to yes in the configuration file watchdog.conf. This adds real time support to wd_keepalive: it will lock itself into memory and there should be no problem even under the highest of loads.
OPTIONSAvailable 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.
- The watchdog device.
- The pid file of the running wd_keepalive.
