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 } |

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. |
