Their own documents, “How Data Is Calculated,” give you a pretty good idea of what data they collect and how they calculate their metrics:

As you mentioned, these calculations are distributed on many machines using the integrated Google architecture, including Map / Reduce:

There is evidence that Google uses its BigTable-DB-Engine (which matches MapReduce) for reading, maps, and youtube.

on dbms2.com , they even say analytics uses MapReduce (can be classified as “insider knowledge”).
