6 wd_identify - get watchdog driver identity
7
9 wd_identify [-c filename|--config-file filename] [-v|--verbose]
10
12 This utility opens /dev/watchdog and gets the identification string
13 from the watchdog which then is printed. The device is closed after‐
14 wards.
15
16 An exit code of zero indicates success in getting the driver identity,
17 while a non-zero exit code indicates an error (not configured in the
18 config file, no device driver loaded, or driver failed to respond to
19 ioctl request).
20
21 The wd_identify tool can only be used without causing a reboot if your
22 kernel is not compiled with the CONFIG_WATCHDOG_NOWAYOUT option
23 enabled.
24
25 Note that the watchdog and/or wd_keepalive daemons may have to be
26 stopped to make sure that wd_identify can access the watchdog device.
27
29 Available command line options are the following:
30
31 -c config-file, --config-file config-file
32 Use config-file as the configuration file instead of the default
33 /etc/watchdog.conf.
34
35 -v, --verbose
36 Print more diagnostic messages. This covers parsing of the con‐
37 fig file and also causes the program to read-back the current
38 watchdog time-out value (if successful in opening the device).
39
41 /dev/watchdog
42 The watchdog device.
