Class SamplingStatCalculator

java.lang.Object
  org.apache.jmeter.visualizers.SamplingStatCalculator

Direct Known Subclasses:

CachingStatCalculator

public class SamplingStatCalculator
extends Object

Aggegate sample data container. Just instantiate a new instance of this class, and then call addSample(SampleResult) a few times, and pull the stats out with whatever methods you prefer.

long	getCount()
Sample	getCurrentSample()
Map<Number,Number[]>	getDistribution()
long	getElapsed() Get the elapsed time for the samples
long	getErrorCount()
double	getErrorPercentage() Returns the raw double value of the percentage of samples with errors that were recorded.
double	getKBPerSecond() Throughput in kilobytes / second
String	getLabel()
Number	getMax()
double	getMaxThroughput()
double	getMean()
Number	getMeanAsNumber()
Number	getMedian()

Constructor Detail

SamplingStatCalculator

public SamplingStatCalculator()

SamplingStatCalculator

public SamplingStatCalculator(String label)

Method Detail

clear

public void clear()

Clear the counters (useful for differential stats)

getCurrentSample

public Sample getCurrentSample()

getElapsed

public long getElapsed()

Get the elapsed time for the samples

Returns:

how long the samples took

getRate

public double getRate()

Returns the throughput associated to this sampler in requests per second. May be slightly skewed because it takes the timestamps of the first and last samples as the total time passed, and the test may actually have started before that start time and ended after that end time.

getBytesPerSecond

public double getBytesPerSecond()

Throughput in bytes / second

Returns:

throughput in bytes/second

getKBPerSecond

public double getKBPerSecond()

Throughput in kilobytes / second

Returns:

Throughput in kilobytes / second

getAvgPageBytes

public double getAvgPageBytes()

calculates the average page size, which means divide the bytes by number of samples.

Returns:

average page size in bytes (0 if sample count is zero)

getLabel

public String getLabel()

addSample

public Sample addSample(SampleResult res)

Records a sample.

getErrorPercentage

public double getErrorPercentage()

Returns the raw double value of the percentage of samples with errors that were recorded. (Between 0.0 and 1.0)

Returns:

the raw double value of the percentage of samples with errors that were recorded.

toString

public String toString()

For debugging purposes, only.

Overrides:

toString in class Object

getErrorCount

public long getErrorCount()

Returns:

errorCount

getMaxThroughput

public double getMaxThroughput()

Returns:

Returns the maxThroughput.

getDistribution

public Map<Number,Number[]> getDistribution()

getPercentPoint

public Number getPercentPoint(double percent)

getCount

public long getCount()

getMax

public Number getMax()

getMean

public double getMean()

getMeanAsNumber

public Number getMeanAsNumber()

getMedian

public Number getMedian()

getMin

public Number getMin()

getPercentPoint

public Number getPercentPoint(float percent)

getStandardDeviation

public double getStandardDeviation()
