Example 6 with Collector

use of zipkin2.collector.Collector in project zipkin by openzipkin.

the class ITKafkaCollector method skipsOnSpanStorageException.

/**
 * Guards against errors that leak from storage, such as InvalidQueryException
 */
@Test

        // the only way we could read this, is if the malformed span was skipped.
        assertThat(receivedSpans.take()).containsExactlyElementsOf(spans);
    }
    assertThat(kafkaMetrics.messages()).isEqualTo(3);
    // storage failure isn't a message failure

Example 7 with Collector

use of zipkin2.collector.Collector in project zipkin by openzipkin.

the class CollectorTest method accept_storageError.

@Test
public void accept_storageError() {
    StorageComponent storage = mock(StorageComponent.class);
    RuntimeException error = new RuntimeException("storage disabled");
    when(storage.spanConsumer()).thenThrow(error);
    collector = new Collector.Builder(LoggerFactory.getLogger("")).metrics(metrics).storage(storage).build();
    collector.accept(TRACE, callback);
    // error is async
    verify(callback).onSuccess(null);
    assertDebugLogIs("Cannot store spans [1, 2, 2, ...] due to RuntimeException(storage disabled)");
    verify(metrics).incrementSpans(4);
    verify(metrics).incrementSpansDropped(4);
}

Example 8 with Collector

use of zipkin2.collector.Collector in project zipkin by openzipkin.

    CollectorMetrics grpcMetrics = metrics.forTransport("grpc");
    Collector collector = Collector.newBuilder(getClass()).storage(storage).sampler(sampler).metrics(grpcMetrics).build();
    return sb -> sb.service("/zipkin.proto3.SpanService/Report", new SpanService(collector, grpcMetrics));
