Constructor Detail

ProportionalZoneFailureDetector

public ProportionalZoneFailureDetector(int minDatapoints,
                                       Duration timeToConsider,
                                       double maxProportionFailures)

Parameters:

minDatapoints - min number of attempts within the time period, to consider this measure reliable

timeToConsider - time for recent attempts (discard any attempts older than this)

maxProportionFailures - proportion (between 0 and 1) where numFailures/dataPoints >= this number means failure
