AeroNet
The Supervisory System
The AeroNet MSS provides distributed mechanisms for the
monitoring, the configuration, the statistics collection and the maintenance
of the MSS Center; roughly speaking, on every hardware unit composing AeroNet
MSS (Servers, Central System, Workstations) a Supervisory System module
resides, responsible for the management of the local resources (both software
modules running on the machine and local hardware components).
In addition to the distributed modules, a coordination module, for supervisory
goals, is present on the , which communicates
with the various distributed Supervisory modules, sending them commands
and requests, and receiving answers and spontaneous information.
This coordination unit has in charge the responsibility of the dialogue
with the user interface running on the Supervisor Workstation;
this Workstation is the only way, for human operators, to interact
with the Supervisory System.
The distributed Supervisory units have in charge the following activities:
-
at system start up, they perform check procedures to verify correctness
of the hardware and software resources, they start the processes that shall
be active on the machine, providing the configuration parameters and controlling
the correct start up
-
at any time, they control the configuration parameters of each module,
communicating to the coordination module on the Central System the possible
run-time changes, occurred as a consequence of a Center's status change
or upon the request of the Center Supervisor
-
they continuously monitor the status of all Center components, thus periodically
polling all machines to verify their behavior, receiving and storing alarms
and anomalies notices coming from the controlled modules, performing recovery
action whenever it is possible and notifying he critical situations to
the coordination unit, in order to be displayed to the personnel
-
they collect statistics coming from the controlled modules, elaborate these
statistics and send them to the coordination
unit.
The coordination unit collects all indications coming from the distributed
Supervisory modules and communicates them to the Supervisor Workstation
user interface: in the same way, it receives commands coming from the Center
Supervisor through the Workstation User interface, and sends them to the
distributed Supervisory modules, thus acting as a .
