xnbd-watchdog - Watch a NBD device as started by xnbd-client(1)
xnbd-watchdog [--timeout SECONDS] [--interval SECONDS] [--recovery-command COMMAND] [--recovery-command-reboot] [NBD_DEVICE]
With the xnbd-watchdog, you can monitor a running xnbd-client and trigger actions on failure.
The following options are supported: --timeout SECONDS Triggers the recovery command action if the watchdog process is unable to connect to the NBD_DEVICE within the given timeout. If not given, this defaults to 10 seconds. --interval SECONDS Specifies the polling interval between probes. If not given, this defaults to 10 seconds. --recovery-command COMMAND If given, the COMMAND is executed if the watchdog is unable to connect the NBD device after timeout exceeded. --recovery-command-reboot This argument is a shortcut for --recovery-command "reboot now". That is, it will reboot the server upon failure.
The following positional options are supported: NBD_DEVICE The local nbd-device to be associated with the remote xnbd-server.
