The workingSet is not included in the resulting document for 2.8 rc1 and r2 nov 26th nightly build for 64-bit windows client.

Just stumbled over this during the m202 course. So for clarification, the section that says "fields vary by platform" is now the main indicator of database performance?

"extra_info" :

{ "note" : "fields vary by platform", "page_faults" : 6100 }
Comment by David Storch [ 30/Dec/14 ]

After consulting with some of our support engineers, we have concluded that statistics already provided on numbers of page faults is a good proxy for the "indexCounters", "recordStats", and "workingSet" sections. These sections provide insight into whether your data / indices fit into memory, or whether there may be thrashing due to a large working set. In many cases, the same information should be available via page fault counts. Closing as Won't Fix.
