Usage Tracking Components for Service-Oriented Middleware Systems

Abstract

Collecting data on user activities is one of the fundamental middleware services in web-enabled systems. The collected data is analyzed and used by various highlevel services, like user profiling, accounting, security auditing, and system health monitoring. In this paper, we present architecture and performance evaluation of usage tracking components for service-oriented middleware systems. Presented middleware components are designed as loosely-coupled usage tracking services, which brings two important benefits. Usage tracking services can be seamlessly integrated with various service-oriented systems without disturbing their operation. Since usage tracking services are loosely-coupled, system users can dynamically deploy and manage multiple usage tracking configurations.
