III-C.1 Event Management Services provided by the Management Platform

SNMP-based management platforms have several components for receiving and processing SNMP traps. Received events are forwarded through a chain of processes, each performing specific actions on them. The services of a filter process can be used to send certain kinds of events to registered management applications in order to allow automatic actions to be taken in case of unusual circumstances. Several filters can be active concurrently, each one defined for certain event attributes like source, type, time, etc. A log daemon stores all event data in a log file. This file can be accessed by users and applications to determine the event history of the network. A GUI application presents a graphical representation of events in so-called Dynamic Workspaces at the platform user interface. These dynamic workspaces can be used to cluster all incoming events or only those according to a specific, pre-defined filter.
