  17. def sampleRate: Float

    returns

    the current sample rate, 0.0-1.0

  18. def sampleRecord(record: Record): Boolean

    Decides if we should record this record or not.

    Decides if we should record this record or not. If this trace is marked as not sampled we just throw away all the records If this trace is marked as None (no decision has been made), consult the sampleTrace impl

    returns

    true if we should keep it, false for throw away

  19. def sampleTrace(traceId: TraceId, sampleRate: Float): Option[Boolean]

    Should we drop this particular trace or send it on to Scribe? True means keep.

    Should we drop this particular trace or send it on to Scribe? True means keep. False means drop.

    traceId

    check if this trace id passes the sampler

    sampleRate

    don't use the sampler's sample rate, instead use this one directly

  20. def sampleTrace(traceId: TraceId): Option[Boolean]

    Should we drop this particular trace or send it on to Scribe? True means keep.

    Should we drop this particular trace or send it on to Scribe? True means keep. False means drop.

    traceId

    check if this trace id passes the sampler

  21. def setSampleRate(sampleRate: Float): Unit

    Set the sample rate.

    Set the sample rate.

    How much to let through? For everything, use 1 = 100.00%
