## org.apache.jmeter.reporters
Class Summariser

    java.lang.Object
      org.apache.jmeter.testelement.AbstractTestElement
          org.apache.jmeter.reporters.Summariser

All Implemented Interfaces:
  Serializable, Cloneable, NoThreadClone, Remoteable, SampleListener, TestElement, TestListener

    public class Summariser

extends AbstractTestElement
implements Serializable, SampleListener, TestListener, NoThreadClone, Remoteable

Generate a summary of the test run so far to the log file and/or standard output. Both running and differential totals are shown. Output is generated every n seconds (default 3 minutes) on the appropriate time boundary, so that multiple test runs on the same time will be synchronised. This is mainly intended for batch (non-GUI) runs Note that the RunningSample start and end times relate to the samples, not the reporting interval. Since the first sample in a delta is likely to have started in the previous reporting interval, this means that the delta interval is likely to be longer than the reporting interval. Also, the sum of the delta intervals will be larger than the overall elapsed time. Data is accumulated according to the test element name.

`COMMENTS, ENABLED, GUI_CLASS, NAME, TEST_CLASS`

Constructor Summary
`Summariser()`
`Summariser(String name)` Constructor for use during startup (intended for non-GUI use)

Method Summary
`void` | `sampleOccurred(SampleEvent e)` Accumulates the sample in two SampleResult objects - one for running totals, and the other for deltas.
`void` | `sampleStarted(SampleEvent e)` A sample has started.
`void` | `sampleStopped(SampleEvent e)` A sample has stopped.
`void` | `testEnded()` Called once for all threads after the end of a test.
`void` | `testEnded(String host)` Called from a different thread as testStarted() but using the same instance.
`void` | `testIterationStart(LoopIterationEvent event)` Each time through a Thread Group's test script, an iteration event is fired for each thread.
`void` | `testStarted()` Called just before the start of the test from the main engine thread.
`void` | `testStarted(String host)` Called once for each Summariser in the test plan.

Constructor Detail

### Summariser

    public Summariser()

### Summariser

    public Summariser(String name)

  Constructor for use during startup (intended for non-GUI use)

  Parameters:
    `name` - of summariser

Method Detail

### sampleOccurred

    public void sampleOccurred(SampleEvent e)

  Accumulates the sample in two SampleResult objects - one for running totals, and the other for deltas.

  Specified by:
    `sampleOccurred` in interface `SampleListener`
  See Also:
    `SampleListener.sampleOccurred(org.apache.jmeter.samplers.SampleEvent)`

### sampleStarted

    public void sampleStarted(SampleEvent e)

  A sample has started.

  Specified by:
    `sampleStarted` in interface `SampleListener`

### sampleStopped

    public void sampleStopped(SampleEvent e)

  A sample has stopped.

  Specified by:
    `sampleStopped` in interface `SampleListener`

### testStarted

    public void testStarted()

  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 `TestListener`
  See Also:
    `StandardJMeterEngine.run()`

### testEnded

    public void testEnded()

  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 `TestListener`
  See Also:
    `StandardJMeterEngine.stopTest()`

### testStarted

    public void testStarted(String host)

  Called once for each Summariser in the test plan. There may be more than one summariser with the same name, however they will all be called before the test proper starts.

  However, note that this applies to a single test only. When running in client-server mode, testStarted() may be invoked after sampleOccurred().

  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 `TestListener`
  Parameters:
    `host` - name of host
  See Also:
    `StandardJMeterEngine.run()`

### testEnded

    public void testEnded(String host)

  Called from a different thread as testStarted() but using the same instance. So synch is needed to fetch the accumulator, and the myName field will already be set up.

  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 `TestListener`
  Parameters:
    `host` - name of host
  See Also:
    `StandardJMeterEngine.stopTest()`

### testIterationStart

    public void testIterationStart(LoopIterationEvent event)

  Each time through a Thread Group's test script, an iteration event is fired for each thread. This will be after the test elements have been cloned, so in general the instance will not be the same as the ones the start/end methods call.

  Specified by:
    `testIterationStart` in interface `TestListener`
