Class Calculator

java.lang.Object
org.apache.jmeter.util.Calculator

public class Calculator extends Object
Class to calculate various items that don't require all previous results to be saved:
  • mean = average
  • standard deviation
  • minimum
  • maximum
  • Constructor Details

    • Calculator

      public Calculator()
    • Calculator

      public Calculator(String label)
  • Method Details

    • clear

      public void clear()
    • addSample

      public void addSample(SampleResult res)
      Add details for a sample result, which may consist of multiple samples. Updates the number of bytes read and sent, error count, startTime and elapsedTime
      Parameters:
      res - the sample result; might represent multiple values
    • addBytes

      public void addBytes(long newValue)
      add received bytes
      Parameters:
      newValue - received bytes
    • 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()
    • getCountLong

      public long getCountLong()
    • 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.
      Returns:
      throughput associated to this sampler in requests per 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
    • getBytesPerSecond

      public double getBytesPerSecond()
      Throughput in bytes / second
      Returns:
      throughput in bytes/second
    • getKBPerSecond

      public double getKBPerSecond()
      Sent Throughput in kilobytes / second
      Returns:
      Sent Throughput in kilobytes / second
    • getSentBytesPerSecond

      public double getSentBytesPerSecond()
      Sent bytes / second
      Returns:
      throughput in bytes/second
    • getSentKBPerSecond

      public double getSentKBPerSecond()
      Sent bytes throughput in kilobytes / second
      Returns:
      Throughput in kilobytes / second
