Constructor Detail

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.

Returns:

min amount of samples

getMinSentinelCount

public int getMinSentinelCount()
