org.apache.jmeter.visualizers
Class SamplingStatCalculator  

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

All Implemented Interfaces:

java.io.Serializable

---

public class SamplingStatCalculator

extends java.lang.Object

implements java.io.Serializable

Aggegate sample data container. Just instantiate a new instance of this class, and then call addSample(SampleResult) 55 a few times, and pull the stats out with whatever methods you prefer.

Constructor Detail

SamplingStatCalculator

private SamplingStatCalculator()

---

SamplingStatCalculator

public SamplingStatCalculator(java.lang.String label)

Use this constructor.

---

SamplingStatCalculator

public SamplingStatCalculator(SamplingStatCalculator stat)

Essentially a copy function

Method Detail

init

private void init()

---

addSamples

public void addSamples(SamplingStatCalculator ssc)

---

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

---

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.

---

getRateString

public java.lang.String getRateString()

Returns a String that represents the throughput associated for this sampler, in units appropriate to its dimension:

The number is represented in requests/second or requests/minute or requests/hour.

Examples: "34.2/sec" "0.1/sec" "43.0/hour" "15.9/min"

---

getPageSize

public double getPageSize()

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

---

getPageSizeString

public java.lang.String getPageSizeString()

formats the rate

---

getLabel

public java.lang.String getLabel()

---

addSample

public Sample addSample(org.apache.jmeter.samplers.SampleResult res)

Records a sample.

---

getSamples

public java.util.List getSamples()

---

getSample

public Sample getSample(int index)

---

getEndTime

private long getEndTime(org.apache.jmeter.samplers.SampleResult res)

---

setStartTime

private void setStartTime(org.apache.jmeter.samplers.SampleResult res)

---

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) If you want a nicer return format, see getErrorPercentageString() 55 .

---

getErrorPercentageString

public java.lang.String getErrorPercentageString()

Returns a String which represents the percentage of sample errors that have occurred. ("0.00%" through "100.00%")

---
