ResMon Cube Sample
Greg Galloway just published a ResMon cube sample on CodePlex that aggregates execution statistics (rolls up information about Analysis Services such as memory usage by object, perfmon counters, aggregation hits/misses, and current session stats) from Analysis Services dynamic management views (DMVs) and makes it easily available for slicing and dicing in a cube. I think this will be a very useful tool to analyze the runtime performance of an Analysis Services server or as a learning tool to understand how to work with DMVs. Kudos to Greg!
