wd_identify - get watchdog driver identity
This utility opens /dev/watchdog
and gets the identification string from
the watchdog which then is printed. The device is closed afterwards.
An exit code of zero indicates success in getting the driver identity, while a
non-zero exit code indicates an error (not configured in the config file, no
device driver loaded, or driver failed to respond to ioctl request).
The wd_identify tool can only be used without causing a reboot if your kernel is
not compiled with the CONFIG_WATCHDOG_NOWAYOUT
Note that the watchdog
daemons may have to be
stopped to make sure that wd_identify
can access the watchdog device.
Available command line options are the following:
- -c config-file, --config-file
- Use config-file as the configuration file instead of
the default /etc/watchdog.conf.
- -v, --verbose
- Print more diagnostic messages. This covers parsing of the
config file and also causes the program to read-back the current watchdog
time-out value (if successful in opening the device).
