Since query/update and others no longer use PageFaultExceptionSections we are no longer collecting stats about the yields.

Comment by David Storch [ 18/Mar/16 ]

scotthernandez, we already evaluated a very similar request, and closed it as Won't Fix: see SERVER-16378. I'll quote my comment from that ticket.

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.

Can this ticket be closed as a duplicate?
