## Class Summariser

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

- All Implemented Interfaces:
    Serializable, Cloneable, NoThreadClone, Searchable, Remoteable, SampleListener, TestElement, TestStateListener

      public class Summariser
      extends AbstractTestElement
      implements Serializable, SampleListener, TestStateListener, 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 30 seconds (property summariser.interval)) 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 This is mainly intended for batch (non-GUI) runs FIXME : Docs below are outdated, need fixing Note that the `SummariserRunningSample` start and end times relate to the samples, not the reporting interval.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.

- - ### 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`
      Parameters:
        `e` - the `SampleEvent` that has occurred
      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`
      Parameters:
        `e` - the `SampleEvent` that has started

    - #### sampleStopped

          public void sampleStopped(SampleEvent e)

      A sample has stopped.
      Specified by:
        `sampleStopped` in interface `SampleListener`
      Parameters:
        `e` - the `SampleEvent` that has stopped

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