The Grid Observatory cluster of Enabling Grids for E-sciencE (EGEE) collects, publishes and analyses data on the behaviour of the EGEE grid. Its aim is to develop a scientific view of the dynamics of grid behaviour and usage. This helps both computer science researchers working in the field of autonomic computing and grid developers seeking to improve reliability, stability and performance. 
%BR% Grid infrastructures, as well as data centers, consist of a variety of hardware and software components, which are, in their own right, complex systems. Grids federate independently managed resources, and answer the requests of communities with evolving behaviour patterns. 
%BR% With extensive monitoring facilities already in place, EGEE grid offers an unprecedented opportunity to observe, and gain understanding of, new computing practices of e-Science.
