Examples with ObservableLongCounter io.opentelemetry.api.metrics.ObservableLongCounter used on opensource projects

Example 1 with ObservableLongCounter

use of io.opentelemetry.api.metrics.ObservableLongCounter in project opentelemetry-java by open-telemetry.

the class SdkMeterProviderTest method removeAsyncInstrument.

@Test
void removeAsyncInstrument() {
    InMemoryMetricReader reader = InMemoryMetricReader.create();
    Meter meter = sdkMeterProviderBuilder.registerMetricReader(reader).build().get(getClass().getName());
    ObservableLongCounter observableCounter1 = meter.counterBuilder("foo").buildWithCallback(measurement -> measurement.record(10, Attributes.builder().put("callback", "one").build()));
    ObservableLongCounter observableCounter2 = meter.counterBuilder("foo").buildWithCallback(measurement -> measurement.record(10, Attributes.builder().put("callback", "two").build()));
    assertThat(reader.collectAllMetrics()).hasSize(1).satisfiesExactly(metricData -> assertThat(metricData).hasLongSum().points().hasSize(2).satisfiesExactlyInAnyOrder(pointData -> assertThat(pointData).hasAttributes(Attributes.builder().put("callback", "one").build()), (Consumer<LongPointData>) longPointData -> assertThat(longPointData).hasAttributes(Attributes.builder().put("callback", "two").build())));
    observableCounter1.close();
    assertThat(reader.collectAllMetrics()).hasSize(1).satisfiesExactly(metricData -> assertThat(metricData).hasLongSum().points().hasSize(1).satisfiesExactlyInAnyOrder((Consumer<LongPointData>) longPointData -> assertThat(longPointData).hasAttributes(Attributes.builder().put("callback", "two").build())));
    observableCounter2.close();
    assertThat(reader.collectAllMetrics()).hasSize(0);
}

Example 2 with ObservableLongCounter

use of io.opentelemetry.api.metrics.ObservableLongCounter in project opentelemetry-java by open-telemetry.

the class SdkObservableLongCounterTest method removeCallback.

@Test
void removeCallback() {
    InMemoryMetricReader sdkMeterReader = InMemoryMetricReader.create();
    ObservableLongCounter counter = sdkMeterProviderBuilder.registerMetricReader(sdkMeterReader).build().get(getClass().getName()).counterBuilder("testCounter").buildWithCallback(measurement -> measurement.record(10));
    assertThat(sdkMeterReader.collectAllMetrics()).satisfiesExactly(metric -> assertThat(metric).hasName("testCounter").hasLongSum().points().hasSize(1));
    counter.close();
    assertThat(sdkMeterReader.collectAllMetrics()).hasSize(0);
