Grid Infrastructure Monitoring as Reliable Information Service

A short overview of Grid infrastructure status monitoring is given followed by a discussion of key concepts for advanced status monitoring systems: passive information gathering based on direct application instrumentation, indirect one based on service and middleware instrumentation, multidimensional matrix testing, and on-demand active testing using non-dedicated user identities. We also propose an idea of augmenting information provided traditionally using Grid information services by information from the infrastructure status monitoring which gives verified and thus valid information only. The approach is demonstrated using a Testbed Status Monitoring Tool prototype developed for a GridLab project.
