Examples with Counter org.apache.samza.metrics.Counter used on opensource projects

Example 1 with Counter

use of org.apache.samza.metrics.Counter in project samza by apache.

the class TestOperatorImpl method testOnTimerUpdatesMetrics.

@Test
public void testOnTimerUpdatesMetrics() {
    TaskContext mockTaskContext = mock(TaskContext.class);
    MetricsRegistry mockMetricsRegistry = mock(MetricsRegistry.class);
    when(mockTaskContext.getMetricsRegistry()).thenReturn(mockMetricsRegistry);
    Counter mockMessageCounter = mock(Counter.class);
    Timer mockTimer = mock(Timer.class);
    when(mockMetricsRegistry.newCounter(anyString(), anyString())).thenReturn(mockMessageCounter);
    when(mockMetricsRegistry.newTimer(anyString(), anyString())).thenReturn(mockTimer);
    Object mockTestOpImplOutput = mock(Object.class);
    OperatorImpl<Object, Object> opImpl = new TestOpImpl(mockTestOpImplOutput);
    opImpl.init(mock(Config.class), mockTaskContext);
    // send a message to this operator
    MessageCollector mockCollector = mock(MessageCollector.class);
    TaskCoordinator mockCoordinator = mock(TaskCoordinator.class);
    opImpl.onTimer(mockCollector, mockCoordinator);
    // verify that it updates metrics
    verify(mockMessageCounter, times(0)).inc();
    verify(mockTimer, times(1)).update(anyLong());
}

Example 2 with Counter

use of org.apache.samza.metrics.Counter in project samza by apache.

the class TestOperatorImpl method testOnMessageUpdatesMetrics.

@Test
public void testOnMessageUpdatesMetrics() {
    TaskContext mockTaskContext = mock(TaskContext.class);
    MetricsRegistry mockMetricsRegistry = mock(MetricsRegistry.class);
    when(mockTaskContext.getMetricsRegistry()).thenReturn(mockMetricsRegistry);
    Counter mockCounter = mock(Counter.class);
    Timer mockTimer = mock(Timer.class);
    when(mockMetricsRegistry.newCounter(anyString(), anyString())).thenReturn(mockCounter);
    when(mockMetricsRegistry.newTimer(anyString(), anyString())).thenReturn(mockTimer);
    Object mockTestOpImplOutput = mock(Object.class);
    OperatorImpl<Object, Object> opImpl = new TestOpImpl(mockTestOpImplOutput);
    opImpl.init(mock(Config.class), mockTaskContext);
    // send a message to this operator
    MessageCollector mockCollector = mock(MessageCollector.class);
    TaskCoordinator mockCoordinator = mock(TaskCoordinator.class);
    opImpl.onMessage(mock(Object.class), mockCollector, mockCoordinator);
    // verify that it updates message count and timer metrics
    verify(mockCounter, times(1)).inc();
    verify(mockTimer, times(1)).update(anyLong());
}

Example 3 with Counter

use of org.apache.samza.metrics.Counter in project samza by apache.

the class TestNoOpMetricsRegistry method testNoOpMetricsHappyPath.

@Test
public void testNoOpMetricsHappyPath() {
    NoOpMetricsRegistry registry = new NoOpMetricsRegistry();
    Counter counter1 = registry.newCounter("testc", "a");
    Counter counter2 = registry.newCounter("testc", "b");
    Counter counter3 = registry.newCounter("testc2", "c");
    Gauge<String> gauge1 = registry.newGauge("testg", "a", "1");
    Gauge<String> gauge2 = registry.newGauge("testg", "b", "2");
    Gauge<String> gauge3 = registry.newGauge("testg", "c", "3");
    Gauge<String> gauge4 = registry.newGauge("testg2", "d", "4");
    Timer timer1 = registry.newTimer("testt", "a");
    Timer timer2 = registry.newTimer("testt", "b");
    Timer timer3 = registry.newTimer("testt2", "c");
    counter1.inc();
    counter2.inc(2);
    counter3.inc(4);
    gauge1.set("5");
    gauge2.set("6");
    gauge3.set("7");
    gauge4.set("8");
    timer1.update(1L);
    timer2.update(2L);
    timer3.update(3L);
    assertEquals(1, counter1.getCount());
    assertEquals(2, counter2.getCount());
    assertEquals(4, counter3.getCount());
    assertEquals("5", gauge1.getValue());
    assertEquals("6", gauge2.getValue());
    assertEquals("7", gauge3.getValue());
    assertEquals("8", gauge4.getValue());
    assertEquals(1, timer1.getSnapshot().getAverage(), 0);
    assertEquals(2, timer2.getSnapshot().getAverage(), 0);
    assertEquals(3, timer3.getSnapshot().getAverage(), 0);
