Monitoring multimedia hardware Standard 1.10

Understanding fault management

Fault management is a subsystem within CallPilot that detects and notifies you of potential or real hardware problems with the multimedia hardware. CallPilot monitors events in the multimedia hardware and raises an alarm when a fault occurs.

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 such as a faulty MPB96 card switching to disabled status.

All events are reported to the fault management server. The fault management server lets the CallPilot server listen and respond to its clients. The interaction is called event processing and the server detects hardware faults in the multimedia hardware.

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 is dependent on the operational status of other components. If a component fails or is stopped, the dependent components go out of service.
