Additionally the CEMF self-management functionality may report faults in the CEMF system itself. Other applications, such as the CEMF Event Manager may also register fault conditions based on performance monitoring threshold violations. The fault conditions are represented internally in CEMF as persistent alarms, and changes to the alarm status are communicated in terms of events. The events represent raising, acknowledging, and clearing of the CEMF alarms. There can also be purely informational events.
CEMF stores alarm and event information and maintains active alarm lists as well as historical data.
The events can be exported over any of the three FM integration interfaces. Different northbound systems may listen to different event channels with different filtering rules. Any of the events described above can be forwarded to northbound FM OSSs as SNMP traps. Basic scoping and filtering mechanisms are available. The scope of event forwarding can be set to any CEMF View.
