      Modifier and Type Method Description
      int getMinSampleCount()
      Returns the amount of samples which a sentinel has to provide to be counted as a valid sentinel.
      int getMinSentinelCount()
      Returns the amount of sentinels which must be available to perform a QoS calculation.
      protected int getPercentile()
      Returns the percentile which should be read from the metrics (sentinels).
      protected int getPeriod()
      Returns the period in seconds, after which the QoS calculation is executed.
      protected int getQuorum()
      Returns how many percent of all api's must be over the defined ratio, so the given api is rejected.

      • QoSConfig

        public QoSConfig​(int percentile,
                 int quorum,
                 int period,
                 int minSampleCount,
                 int minSentinelCount)
        Creates a new global configuration object for the QoS.
        Parameters:
        percentile - the percentile which should be read from the metrics (sentinels).
        quorum - defines how many percent of all api's must be over the defined ratio, so the given api is rejected.
        period - defines the period in seconds after which the calculation is executed.
        minSampleCount - defines the min. samples count of a sentinel so it can be used for the QoS calc.
        minSentinelCount - defines the min. sentinel count used to perform a QoS calc.
