Examples with Sampler io.jaegertracing.spi.Sampler used on opensource projects

Example 11 with Sampler

use of io.jaegertracing.spi.Sampler in project jaeger-client-java by jaegertracing.

the class RemoteControlledSamplerTest method testUpdateToPerOperationSamplerReplacesProbabilisticSampler.

@Test
public void testUpdateToPerOperationSamplerReplacesProbabilisticSampler() throws Exception {
    List<PerOperationSamplingParameters> operationToSampler = new ArrayList<>();
    operationToSampler.add(new PerOperationSamplingParameters("operation", new ProbabilisticSamplingStrategy(0.1)));
    OperationSamplingParameters parameters = new OperationSamplingParameters(0.11, 0.22, operationToSampler);
    SamplingStrategyResponse response = new SamplingStrategyResponse(null, null, parameters);
    when(samplingManager.getSamplingStrategy(SERVICE_NAME)).thenReturn(response);
    undertest.updateSampler();
    PerOperationSampler perOperationSampler = new PerOperationSampler(2000, parameters);
    Sampler actualSampler = undertest.getSampler();
    assertEquals(perOperationSampler, actualSampler);
}

Example 12 with Sampler

use of io.jaegertracing.spi.Sampler in project jaeger-client-java by jaegertracing.

the class ProbabilisticSamplerTest method testSamplingBoundariesPositive.

@Test
public void testSamplingBoundariesPositive() {
    double samplingRate = 0.5;
    long halfwayBoundary = 0x3fffffffffffffffL;
    Sampler sampler = new ProbabilisticSampler(samplingRate);
    assertTrue(sampler.sample("", halfwayBoundary).isSampled());
    assertFalse(sampler.sample("", halfwayBoundary + 2).isSampled());
