Authors: Laurence Field, Felix Ehm, Joanna Huang, Min Tsai Grid Information Systems are mission-critical components in todays production grid infrastructures. They enable users, applications and services to discover which services exists in the infrastructure and further information about the service structure and state. It is therefore important that the information system components themselves are functioning correctly and that the information content is reliable. Grid Status (GStat) is a tool that monitors the structural integrity of the EGEE information system, which is a hierarchical system built out of more than 260 site level and about 70 global aggregation services. GStat checks the content and presents summary and history displays for Grid operators and System Administrators. A major new version, GStat 2.0, aims to build on the experience of GStat in production and provide additional functionality which enables it to be extended and combined with other tools. This paper describes the new architecture used for GStat 2.0 and how it can be at all levels to help provide a reliable information system.
