Abstract: A system monitors performance in a network that includes several network resources. The system obtains a list of targets in the network. The targets include selected ones of the resources. The system sends a request to the targets, receives responses from the targets, and determines a status of the targets based on the received responses or a lack of responses from the targets. The system then analyzes the status of the targets to determine compliance with the service-level guarantee.

Abstract: Systems and methods consistent with the present invention perform message parsing in a distributed component-based network management system using a parsing knowledge structure called a Message Class Grammar (MCG) containing the set of all potential pre-calculated parsing sequences for an active network element. The MCG may be customized to the messages of different active network elements. A universal parsing procedure (UPP) may be used to traverse the hierarchy structure of the MCG. Tracing the MCG hierarchy from the root node along class-subclass arcs until a terminal node is reached determines the parsing sequence for a particular message. The MCG may be developed with a text editor or with a graphical user interface that enables a non-programmer to edit the parser structure.
