Cluster monitoring system with content-based event routing

摘要

A node manager ( 300 ) resides on a node ( 104 ) in a cluster computing system ( 100 ) and transfers information and events being communicated across the node ( 104 ) to a broker ( 102 ) coupled to the node manager ( 300 ). The broker ( 102 ) transmits information to client devices ( 106 ) who subscribe to particular events. The node manager ( 300 ) includes an adapter ( 304 ) that interprets events occurring on the system and publishes messages to the broker, and a system probe ( 302 ) that publishes information to the broker ( 102 ) in accordance with a configurable schedule. An autonomic agent ( 400 ) measures the rate of information loss between the node ( 104 ) and client ( 106 ) and regulates the rate of information by adjusting one or more information flow control points within the system once an overload state is detected.
