Class RunningSample

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

public class RunningSample extends Object

Running 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.

Please note that this class is not thread-safe. The calling class is responsible for ensuring thread safety if required. Versions prior to 2.3.2 appeared to be thread-safe but weren't as label and index were not final. Also the caller needs to synchronize access in order to ensure that variables are consistent.

  • Constructor Details

    • RunningSample

      public RunningSample(String label, int index)
      Use this constructor to create the initial instance
      Parameters:
      label - the label for this component
      index - the index of this component
    • RunningSample

      public RunningSample(RunningSample src)
      Copy constructor to create a duplicate of existing instance (without the disadvantages of clone()
      Parameters:
      src - existing RunningSample to be copied
  • Method Details

    • clear

      public void clear()
      Clear the counters (useful for differential stats)
    • 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.
      Returns:
      throughput associated with this sampler per second
    • getRatePerMin

      public double getRatePerMin()
      Returns the throughput associated to this sampler in requests per min. 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 with this sampler per minute
    • getRateString

      public 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"

      Returns:
      a String representation of the rate the samples are being taken at.
    • getLabel

      public String getLabel()
      Returns:
      the label for this component
    • getIndex

      public int getIndex()
      Returns:
      the index of this component
    • addSample

      public void addSample(SampleResult res)
      Records a sample.
      Parameters:
      res - sample to record
    • addSample

      public void addSample(RunningSample rs)
      Adds another RunningSample to this one. Does not check if it has the same label and index.
      Parameters:
      rs - sample to add
    • getMin

      public long getMin()
      Returns the time in milliseconds of the quickest sample.
      Returns:
      the time in milliseconds of the quickest sample.
    • getMax

      public long getMax()
      Returns the time in milliseconds of the slowest sample.
      Returns:
      the time in milliseconds of the slowest sample.
    • getAverage

      public long getAverage()
      Returns the average time in milliseconds that samples ran in.
      Returns:
      the average time in milliseconds that samples ran in.
