Abstract

The successful deployment of next-generation distributed systems is significantly dependent on the efficient management support that improves the performance and reliability of these applications at run-time. This paper motivates and describes a programmable agents approach for active monitoring as an important attribute for supporting scalable, highly-responsive and non-intrusive management architecture. Active monitoring enables defining re-configurable and self-directed management tasks that can be modified automatically at run-time in order to track the system behavior. Based on observed events and users' monitoring demands, monitoring agents can dynamically customize their assigned tasks and initiate the appropriate monitoring actions. This avoids activating unnecessary monitoring tasks and provides a dynamic monitoring operations. The presented system, which is referred to as HiFi, supports a comprehensive environment including code instrumentation, user subscription, event filtering and action service. The paper also shows monitoring examples that illustrates the application and the effectiveness of active monitoring in managing large-scale distributed systems.
