Event processing
An event is any change in system configuration or operational state. An
event is also any action taken by the system that requires user notification.
Events can be as insignificant as a user logon attempt or as serious as a
faulty MPB96 card switching to disabled status.
All events are reported to the fault management server, a subsystem within
the CallPilot server. The fault management server enables the CallPilot
server to listen and respond to its clients. The interaction is called event
processing and is the means by which the server detects hardware faults.
Alarm notification
Alarms are warnings generated by events. Alarms communicate the same
information as events. However, alarms are reported in the Alarm Monitor
instead of the Event Browser, and are managed differently than events.
When an alarm appears in the Alarm Monitor, you must investigate the
problem, isolate it, and then fix the cause of the problem. When you fix the
problem, the alarm is cleared from the Alarm Monitor.
Component dependencies
The status of some components are dependent on the operational status
of other components. If a component fails or is stopped, the dependent
components go out of service.

Detecting hardware problems
Typically, you first become aware of a hardware problem when an alarm is
raised. All hardware faults produce an alarm (or series of alarms, depending
on the problem) in the Alarm Monitor.
