$0 manages the Platform's Maintenance command and communication to compute server guest services.

The 'start' ..... operation starts the guestAgent service daemon.

The 'stop' ...... operation stops the guestAgent service daemon.

The 'reload' .... operation stops and then starts the guestAgent service daemon.
|

The 'status' .... operation checks the status of the guestAgent service daemon.

The 'monitor' ... operation indicates the in-service status of the guestAgent service daemon.
|
|
The 'validate-all' operation reports whether the parameters are valid.
|

The 'meta-data' . operation reports the guestAgent's meta-data information.
