WATCHDOG.CONF(5)

NAME
watchdog.conf - configuration file for the watchdog daemon

DESCRIPTION
This file carries all configuration options for the Linux watchdog daemon. Each option has to be written on a line for itself. Comments start with '#'. Blanks are ignored except after the '=' sign. An empty text after the '=' sign disables the feature as long as that makes sense.

OPTIONS

interval = <interval>
    Set the highest possible interval between two writes to the watchdog device. The device is triggered after each check regardless of the time it took. After finishing all checks watchdog goes to sleep for a full cycle of <interval> seconds. Default value is 1 second. The kernel drivers expects a write command every minute. Otherwise the system will be rebooted. Therefore an interval of more than a minute can only be used with the -f command-line option.

logtick = <logtick>
    If you enable verbose logging, a message is written into the syslog or a logfile. While this is nice, it is not necessary to get a message every 10 seconds which really fills up disk and needs CPU. logtick allows adjustment of the number of intervals skipped before a log message is written. If you use logtick = 60 and interval = 10, only every 10 minutes (600 seconds) a message is written. This may make the exact time of a crash harder to find but greatly reduces disk usage and administrator nerves if you're looking for a particular syslog entry in between of watchdog messages.

watchdog-device = <device>
    Set the watchdog device name. Default is to disable keep alive support.

watchdog-timeout = <timeout>
    Set the watchdog device timeout during startup. If not set, a default is used that should be set to the kernel timer margin at compile time.

realtime = <yes|no>
    If set to yes watchdog will lock itself into memory so it is never swapped out.

priority = <schedule priority>
    In realtime mode set the realtime scheduler priority using sched_setscheduler(2). In non-realtime mode set the scheduling priority using setpriority(2).

FILES

/etc/watchdog.conf
    The watchdog configuration file

/etc/watchdog.d/platform
    An optional configuration file to enable or disable running the wd_keepalive program. If the file /etc/watchdog.d/platform exists, it is sourced by the /etc/default/watchdog script. To enable the watchdog to run at system startup, edit the file /etc/watchdog.d/platform to contain the line:
       run_watchdog=1
    To prevent the watchdog from running at startup, edit the file /etc/watchdog.d/platform to contain the line:
       run_watchdog=0
