NAME

       xnbd-watchdog - Watch a NBD device as started by xnbd-client(1)

SYNOPSIS

       xnbd-watchdog [--timeout SECONDS] [--interval SECONDS] [--recovery-command COMMAND]
       [--recovery-command-reboot] [NBD_DEVICE]

DESCRIPTION

       With the xnbd-watchdog, you can monitor a running xnbd-client and trigger actions on
       failure.

OPTIONS

       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.

POSITIONAL ARGUMENTS

       The following positional options are supported:

       NBD_DEVICE
           The local nbd-device to be associated with the remote xnbd-server.
