Package org.apache.jmeter.timers.poissonarrivals

Class PreciseThroughputTimer

java.lang.Object
org.apache.jmeter.testelement.AbstractTestElement
org.apache.jmeter.timers.poissonarrivals.PreciseThroughputTimer
All Implemented Interfaces:
Serializable, Cloneable, Searchable, TestBean, org.apache.jmeter.testelement.TestElement, TestStateListener, Timer
public class PreciseThroughputTimer extends AbstractTestElement implements Cloneable, Timer, TestStateListener, TestBean
This timer generates Poisson arrivals with constant throughput. On top of that, it tries to maintain the exact amount of arrivals for a given timeframe (throughputPeriod).
Since:
4.0

    • clone

      public Object clone()
      Specified by:
      clone in interface org.apache.jmeter.testelement.TestElement
      Overrides:
      clone in class AbstractTestElement

    • testStarted

      public void testStarted()
      Description copied from interface: TestStateListener

      Called just before the start of the test from the main engine thread. This is before the test elements are cloned. Note that not all the test variables will have been set up at this point.

      N.B. testStarted() and testEnded() are called from different threads.

      Specified by:
      testStarted in interface TestStateListener

    • testStarted

      public void testStarted(String host)
      Description copied from interface: TestStateListener

      Called just before the start of the test from the main engine thread. This is before the test elements are cloned. Note that not all the test variables will have been set up at this point.

      N.B. testStarted() and testEnded() are called from different threads.

      Specified by:
      testStarted in interface TestStateListener
      Parameters:
      host - name of host

    • testEnded

      public void testEnded()
      Description copied from interface: TestStateListener

      Called once for all threads after the end of a test. This will use the same element instances as at the start of the test.

      N.B. testStarted() and testEnded() are called from different threads.

      Specified by:
      testEnded in interface TestStateListener
      See Also:

    • testEnded

      public void testEnded(String s)
      Description copied from interface: TestStateListener

      Called once for all threads after the end of a test. This will use the same element instances as at the start of the test.

      N.B. testStarted() and testEnded() are called from different threads.

      Specified by:
      testEnded in interface TestStateListener
      Parameters:
      s - name of host

    • delay

      public long delay()
      Description copied from interface: Timer
      This method is called after a sampling process is done to know how much time the sampling thread has to wait until sampling again.
      Specified by:
      delay in interface Timer
      Returns:
      the computed delay value.

    • getThroughput

      public double getThroughput()
      Returns number of generated samples per getThroughputPeriod()
      Returns:
      number of samples per getThroughputPeriod()

    • setThroughput

      public void setThroughput(double throughput)
      Sets number of generated samples per getThroughputPeriod()
      Parameters:
      throughput - number of samples per getThroughputPeriod()

    • getThroughputPeriod

      public int getThroughputPeriod()
      Allows to use business values for throughput configuration. For instance, 100 samples per hour vs 100 samples per minute.
      Returns:
      the length of the throughput period in seconds
