Abstract
An event correlation system for network management has computer code for at least one model of a process to be run on a node of a network, where said process is intended to be run on a different node of the network than the model. The correlation system also has code for an alarm monitor comparing the apparent behavior of the model to actual events generated by the process and generating alarm messages when the actual events of the process do not match expected events from the model. It also has code for an event correlation utility; and means for communicating alarms from the alarm monitor to the event correlation utility.
