      Use Case

      As a... Driver user
      I want... to ensure that server monitors correctly record heartbeat durations
      So that... server selection can correctly determine 

      User Impact

      • At least once customer has reported degraded performance on their production cluster due to server selection choosing the wrong server

      Dependencies

      • upstream and/or downstream requirements and timelines to bear in mind

      Unknowns

      • questions that need to be answered to determine implementation

      Acceptance Criteria

      Implementation Requirements

      • Fix Monitor class to ensure that it does not begin erroneously record rtt as 0ms

      Testing Requirements

      • Add integration tests to verify that rtt sampler is not accumulating zeros

      Documentation Requirements

      • None

      Follow Up Requirements
