Class LogNormal

java.lang.Object

com.github.tomakehurst.wiremock.http.LogNormal

All Implemented Interfaces:

DelayDistribution

public final class LogNormal
extends Object
implements DelayDistribution

Returns log normally distributed values. Takes two parameters, the median (50th percentile) of the lognormal and the standard deviation of the underlying normal distribution, plus an optional maximum value to truncate the result by resampling to prevent an extra long tail

The larger the standard deviation the longer the tails.

Constructor Details

LogNormal

public LogNormal(double median,
 double sigma,
 Double maxValue)

Parameters:

median - 50th percentile of the distribution in millis

sigma - standard deviation of the underlying normal distribution, a larger value produces a longer tail

maxValue - the maximum value to truncate the distribution at, or null to disable truncation

LogNormal

public LogNormal(double median,
 double sigma)

Parameters:

median - 50th percentile of the distribution in millis

sigma - standard deviation of the distribution, a larger value produces a longer tail

Method Details

sampleMillis

public long sampleMillis()

Description copied from interface: DelayDistribution

Samples a delay in milliseconds from the distribution.

Specified by:

sampleMillis in interface DelayDistribution

Returns:

next delay in millis
