/** |
| 31 |
|
* A startup component for the Local Clients. |
| 32 |
+ |
* This class starts the CORBA client used for alerting |
| 33 |
+ |
* purposes. It reads data using the ClientServant from CORBA |
| 34 |
+ |
* calls by the i-scream client interface. This data is then |
| 35 |
+ |
* used by the MonitorManager to pass to Monitors. Monitors then |
| 36 |
+ |
* analyse the data and raise alerts if needed, these are passed to |
| 37 |
+ |
* the Alerters, which send out alerts. They are looked after by |
| 38 |
+ |
* the AlerterManager. |
