With the xnbd-watchdog, you can monitor a running xnbd-client and
trigger actions on failure.
The following options are supported:
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.
Specifies the polling interval between probes. If not given, this
defaults to 10 seconds.
If given, the COMMAND is executed if the watchdog is unable to
connect the NBD device after timeout exceeded.
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:
The local nbd-device to be associated with the remote xnbd-server.
