    XMLWordPrintableJSON

Details

    • Sharding NYC
    • v5.0

    Description

      Should collect latency information as a histogram with coarse grained buckets (0-10ms,11-100ms,101-1000ms, 1001-10000ms, 10001+ms)
      Should track total number of invocations that complete
      Should report these metrics in serverStatus to be consumed by FTDC.
      Should report these metrics in currentOp if there is a resharding operation currently in progress.
