Calculator

public Calculator()

Calculator

public Calculator(String label)
Method Detail

clear

public void clear()

addValue

@Deprecated
public void addValue(long newValue)
Deprecated. Use addSample(SampleResult) instead

Add the value for a single sample.

Parameters:
newValue -
See Also:
addValue(long, int)

addBytes

public void addBytes(long newValue)

addSample

public void addSample(SampleResult res)
Add details for a sample result, which may consist of multiple samples. Updates the number of bytes read, error count, startTime and elapsedTime

Parameters:
res - the sample result; might represent multiple values
See Also:
addValue(long, int)

getTotalBytes

public long getTotalBytes()

getMean

public double getMean()

getMeanAsNumber

public Number getMeanAsNumber()

getStandardDeviation

public double getStandardDeviation()

getMin

public long getMin()

getMax

public long getMax()

getCount

public int getCount()

getLabel

public String getLabel()

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.

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.


getAvgPageBytes

public double getAvgPageBytes()
calculates the average page size, which means divide the bytes by number of samples.

Returns:
average page size in bytes

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
