public enum TrackedRequestFinalState
extends java.lang.Enum<TrackedRequestFinalState>

The final state of a single request that is tracked by operation tracker. Note that, after request is created in router, it is not guaranteed to be sent out. The request may already time out during connection checkout etc. This enum is consumed by operation tracker to change success/failure counter and determine whether to update Histograms.
