FailureDetector

Type Members

sealed trait Config extends AnyRef

Base type used to identify and configure the FailureDetector.
case class DarkModeConfig(minPeriod: Duration = 5.seconds, threshold: Double = 2, windowSize: Int = 100, closeThreshold: Int = 1) extends Config with Product with Serializable

Indicated to use the default ping frequency and mark busy threshold; but it just exports stats instead of actually marking an endpoint as busy.
case class Param(param: Config) extends Product with Serializable

Helper class for configuring a FailureDetector within a com.twitter.finagle.Stackable client
case class ThresholdConfig(minPeriod: Duration = 5.seconds, threshold: Double = 2, windowSize: Int = 100, closeThreshold: Int = 1) extends Config with Product with Serializable

Indicated to use the com.twitter.finagle.mux.ThresholdFailureDetector configured with these values when creating a new detector.
Indicated to use the com.twitter.finagle.mux.ThresholdFailureDetector configured with these values when creating a new detector.
The default windowSize and threshold are chosen from examining a representative ping distribution in a Twitter data center. With long tail distribution, we want a reasonably large window size to capture long RTTs in the history. A small threshold makes the detection sensitive to potential failures. There can be a low rate of false positive, which is fine in most production cases with cluster redundancy.
