Example 1 with BackPressureSensor

use of com.twitter.heron.healthmgr.sensors.BackPressureSensor in project incubator-heron by apache.

the class BackPressureDetectorTest method testConfigAndFilter.

@Test

    HealthPolicyConfig config = mock(HealthPolicyConfig.class);
    when(config.getConfig(CONF_NOISE_FILTER, 20)).thenReturn(50);

    Map<String, ComponentMetrics> topologyMetrics = new HashMap<>();
    topologyMetrics.put("bolt", compMetrics);
    BackPressureSensor sensor = mock(BackPressureSensor.class);
    when(sensor.get()).thenReturn(topologyMetrics);
    BackPressureDetector detector = new BackPressureDetector(sensor, config);
    List<Symptom> symptoms = detector.detect();
    Assert.assertEquals(1, symptoms.size());
    compMetrics = new ComponentMetrics("bolt", "i1", METRIC_BACK_PRESSURE.text(), 45);
