Class PreciseThroughputTimer

java.lang.Object

org.apache.jmeter.testelement.AbstractTestElement

org.apache.jmeter.timers.poissonarrivals.PreciseThroughputTimer

All Implemented Interfaces:

Serializable, Cloneable, Searchable, TestBean, 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

PreciseThroughputTimer

public PreciseThroughputTimer()

Method Detail

clone

public Object clone()

Specified by:

clone in interface 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

See Also:

StandardJMeterEngine.run()

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

See Also:

StandardJMeterEngine.run()

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:

StandardJMeterEngine.stopTest()

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

See Also:

StandardJMeterEngine.stopTest()

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

setThroughputPeriod

public void setThroughputPeriod(int throughputPeriod)
