Example 1 with ViewBuilderImpl

use of io.opentelemetry.sdk.metrics.internal.view.ViewBuilderImpl in project opentelemetry-java by open-telemetry.

the class SdkMeterProviderTest method viewSdk_capturesBaggageFromContext.

@Test

    InstrumentSelector selector = InstrumentSelector.builder().setType(InstrumentType.COUNTER).setName("test").build();
    InMemoryMetricReader reader = InMemoryMetricReader.create();
    SdkMeterProvider provider = sdkMeterProviderBuilder.registerMetricReader(reader).registerView(selector, ((ViewBuilderImpl) View.builder().setAggregation(Aggregation.sum())).appendAllBaggageAttributes().build()).build();
    Meter meter = provider.get(SdkMeterProviderTest.class.getName());
    Baggage baggage = Baggage.builder().put("baggage", "value").build();
    Context context = Context.root().with(baggage);
    LongCounter counter = meter.counterBuilder("test").build();
    // Make sure whether or not we explicitly pass baggage, all values have it appended.
    counter.add(1, Attributes.empty(), context);
    // Also check implicit context
    try (Scope ignored = context.makeCurrent()) {
        counter.add(1, Attributes.empty());
    }
    // Now make sure all metrics have baggage appended.
    // Implicitly we should have ONLY ONE metric data point that has baggage appended.
    assertThat(reader.collectAllMetrics()).satisfiesExactly(metric -> assertThat(metric).hasName("test").hasLongSum().isCumulative().points().satisfiesExactly(point -> assertThat(point).hasAttributes(Attributes.builder().put("baggage", "value").build())));
