Examples with DerivedDoubleGauge io.opencensus.metrics.DerivedDoubleGauge used on opensource projects

Example 1 with DerivedDoubleGauge

use of io.opencensus.metrics.DerivedDoubleGauge in project instrumentation-java by census-instrumentation.

the class MetricRegistryImplTest method getMetrics.

@Test
public void getMetrics() {
    LongGauge longGauge = metricRegistry.addLongGauge(NAME, METRIC_OPTIONS);
    LongPoint longPoint = longGauge.getOrCreateTimeSeries(LABEL_VALUES);
    longPoint.set(200);
    DoubleGauge doubleGauge = metricRegistry.addDoubleGauge(NAME_2, METRIC_OPTIONS);
    DoublePoint doublePoint = doubleGauge.getOrCreateTimeSeries(LABEL_VALUES);
    doublePoint.set(-300.13);
    DerivedLongGauge derivedLongGauge = metricRegistry.addDerivedLongGauge(NAME_3, METRIC_OPTIONS);
    derivedLongGauge.createTimeSeries(LABEL_VALUES, null, longFunction);
    DerivedDoubleGauge derivedDoubleGauge = metricRegistry.addDerivedDoubleGauge(NAME_4, METRIC_OPTIONS);
    derivedDoubleGauge.createTimeSeries(LABEL_VALUES, null, doubleFunction);
    Collection<Metric> metricCollections = metricRegistry.getMetricProducer().getMetrics();
    assertThat(metricCollections.size()).isEqualTo(4);
    assertThat(metricCollections).containsExactly(Metric.createWithOneTimeSeries(LONG_METRIC_DESCRIPTOR, TimeSeries.createWithOnePoint(ALL_VALUES, Point.create(Value.longValue(200), TEST_TIME), null)), Metric.createWithOneTimeSeries(DOUBLE_METRIC_DESCRIPTOR, TimeSeries.createWithOnePoint(ALL_VALUES, Point.create(Value.doubleValue(-300.13), TEST_TIME), null)), Metric.createWithOneTimeSeries(DERIVED_LONG_METRIC_DESCRIPTOR, TimeSeries.createWithOnePoint(ALL_VALUES, Point.create(Value.longValue(5), TEST_TIME), null)), Metric.createWithOneTimeSeries(DERIVED_DOUBLE_METRIC_DESCRIPTOR, TimeSeries.createWithOnePoint(ALL_VALUES, Point.create(Value.doubleValue(5.0), TEST_TIME), null)));
}
