    } catch (RuntimeException e) {
        throw new ConfigurationException("Failed to parse view config", e);
    }
}

Example 2 with Aggregation

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

the class SdkMeterProviderTest method sdkMeterProvider_supportsMultipleCollectorsDelta.

@Test
void sdkMeterProvider_supportsMultipleCollectorsDelta() {
    // Note: we use a view to do delta aggregation, but any view ALWAYS uses double-precision right
    // now.
    InMemoryMetricReader collector1 = InMemoryMetricReader.createDelta();
    InMemoryMetricReader collector2 = InMemoryMetricReader.createDelta();
    SdkMeterProvider meterProvider = sdkMeterProviderBuilder.registerMetricReader(collector1).registerMetricReader(collector2).registerView(InstrumentSelector.builder().setType(InstrumentType.COUNTER).setName("testSum").build(), View.builder().setAggregation(Aggregation.sum()).build()).build();
    Meter sdkMeter = meterProvider.get(SdkMeterProviderTest.class.getName());
    LongCounter counter = sdkMeter.counterBuilder("testSum").build();
    long startTime = testClock.now();
    counter.add(1L);
    testClock.advance(Duration.ofSeconds(1));
    assertThat(collector1.collectAllMetrics()).satisfiesExactly(metric -> assertThat(metric).hasResource(RESOURCE).hasName("testSum").hasLongSum().isDelta().points().satisfiesExactly(point -> assertThat(point).hasStartEpochNanos(startTime).hasEpochNanos(testClock.now()).hasValue(1)));
    long collectorOneTimeOne = testClock.now();
    counter.add(1L);
    testClock.advance(Duration.ofSeconds(1));
    // Make sure collector 2 sees the value collector 1 saw
    assertThat(collector2.collectAllMetrics()).satisfiesExactly(metric -> assertThat(metric).hasResource(RESOURCE).hasName("testSum").hasLongSum().isDelta().points().satisfiesExactly(point -> assertThat(point).hasStartEpochNanos(startTime).hasEpochNanos(testClock.now()).hasValue(2)));
    // Make sure Collector 1 sees the same point as 2, when it collects.
    assertThat(collector1.collectAllMetrics()).satisfiesExactly(metric -> assertThat(metric).hasResource(RESOURCE).hasName("testSum").hasLongSum().isDelta().points().satisfiesExactly(point -> assertThat(point).hasStartEpochNanos(collectorOneTimeOne).hasEpochNanos(testClock.now()).hasValue(1)));
}

Example 3 with Aggregation

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

the class ViewConfigTest method toView.

@Test
void toView() {
    View view = ViewConfig.toView(ViewSpecification.builder().name("name").description("description").aggregation("sum").attributeKeys(Arrays.asList("foo", "bar")).build());
    assertThat(view.getName()).isEqualTo("name");
    assertThat(view.getDescription()).isEqualTo("description");
    assertThat(view.getAggregation()).isEqualTo(Aggregation.sum());
    assertThat(ImmutableView.getAttributesProcessor(view).process(Attributes.builder().put("foo", "val").put("bar", "val").put("baz", "val").build(), Context.current())).containsEntry("foo", "val").containsEntry("bar", "val").satisfies((Consumer<Attributes>) attributes -> assertThat(attributes.get(AttributeKey.stringKey("baz"))).isBlank());
