RASSMon: Realtime asynchronous service status monitoring

The operation and maintenance of large distributed systems that are subject to high QoS conditions has led to the need of designing and developing advanced monitoring tools that facilitate the administration of the critical services required by the user communities. RASSMon is a portable, reliable, secure software platform able to collect monitoring data from multiple sources in heterogeneous environments that offers an unified overview on the resource and service status in distributed systems such as computing grids. This article presents the challenges encountered in order to create a real-time management tool for monitoring grid services, with reference to some of the latest theoretical advances in programming language semantics.
