Examples with Span zipkin.Span used on opensource projects

Example 6 with Span

use of zipkin.Span in project zipkin by openzipkin.

the class CassandraSpanConsumerTest method dontLogTimestampMissingOnMidTierServerSpan.

@Test
public void dontLogTimestampMissingOnMidTierServerSpan() {
    Span span = TestObjects.TRACE.get(0);
    accept(span);
    verify(mockAppender, never()).doAppend(considerSwitchStrategyLog());
}

Example 7 with Span

use of zipkin.Span in project zipkin by openzipkin.

the class CassandraSpanConsumerTest method doesntIndexCoreOrNonStringAnnotations.

/**
   * Core/Boundary annotations like "sr" aren't queryable, and don't add value to users. Address
   * annotations, like "sa", don't have string values, so are similarly not queryable. Skipping
   * indexing of such annotations dramatically reduces the load on cassandra and size of indexes.

@Test
public void doesntIndexCoreOrNonStringAnnotations() {
    Span span = TestObjects.TRACE.get(1);
    assertThat(span.annotations).extracting(a -> a.value).matches(Constants.CORE_ANNOTATIONS::containsAll);

Example 8 with Span

use of zipkin.Span in project zipkin by openzipkin.

Example 10 with Span

use of zipkin.Span in project zipkin by openzipkin.

the class CassandraSpanStoreTest method rawTraceStoredWithoutAdjustments.

/** Cassandra indexing is performed separately, allowing the raw span to be stored unaltered. */
