In Konark, a network monitoring system based on mobile-agents,agents can communicate witheach other to perform system-wide correlation of data.To minimize management efforts, our system incorporatesmechanisms to detect and self-recover frominternal failures in a decentralized and scalable fashion.In this paper, we discuss the mechanisms for self-recoveryachievedby using the same mechanisms as those used for monitoringcomputing resources in thenetwork.Self-monitoring of Konark also provides all the features ofnetwork monitoring,such as dynamic extensibility, active monitoring, andonline-correlation of data.The security mechanisms of Konark are also discussed.This work demonstrates that mobile-agent based approach is aviable alternative forbuilding robust and secure network monitoring systems.
