Investigate changes in SERVER-51730: Report histogram data on how long it takes cursors to drain

XMLWordPrintableJSON

      Description

      Downstream Change Summary

      Added a new server status metric to count the number of cursors with lifespans between pre-defined lifespan buckets. The buckets are 0s - 1s, 1s - 5s, 5s - 15s, 15s - 30s, 30s - 1m, 1m - 10m, and >= 10m. The ranges exclude the lower number include the upper number (so 1s - 5s means 1s < t <= 5s).

      The names of these buckets are:

      "cursor.lifespan.lessThan1Second", "cursor.lifespan.lessThan5Seconds", "cursor.lifespan.lessThan15Seconds", "cursor.lifespan.lessThan30Seconds", "cursor.lifespan.lessThan1Minute", "cursor.lifespan.lessThan10Minutes", "cursor.lifespan.greaterThanOrEqual10Minutes",

      Description of Linked Ticket

      Report histogram data in serverStatus on cursor drain times (i.e. the time from when a cursor is created to when it is exhausted or killed).
