Examples with Meter com.netflix.spectator.api.Meter used on opensource projects

Example 1 with Meter

use of com.netflix.spectator.api.Meter in project kork by spinnaker.

the class StackdriverWriterTest method testMeasurementsToTimeSeries.

@Test
public void testMeasurementsToTimeSeries() throws IOException {
    Measurement measureAXY = new Measurement(idAXY, clock.monotonicTime(), 1);
    Measurement measureBXY = new Measurement(idBXY, clock.monotonicTime(), 2);
    DefaultRegistry testRegistry = new DefaultRegistry(clock);
    testRegistry.counter(idAXY).increment();
    testRegistry.counter(idBXY).increment(2);
    // Note this writer is still using the mock Monitoring client stub.
    TestableStackdriverWriter spy = spy(new TestableStackdriverWriter(writerConfig.build()));
    Meter counterA = testRegistry.counter(idAXY);
    Meter counterB = testRegistry.counter(idBXY);
    doReturn(new TimeSeries()).when(spy).measurementToTimeSeries(eq(descriptorA.getType()), eq(testRegistry), eq(counterA), eq(measureAXY));
    doReturn(new TimeSeries()).when(spy).measurementToTimeSeries(eq(descriptorB.getType()), eq(testRegistry), eq(counterB), eq(measureBXY));
    // Just testing the call flow produces descriptors since
    // we return empty TimeSeries values.
    spy.registryToTimeSeries(testRegistry);
}

Example 2 with Meter

use of com.netflix.spectator.api.Meter in project kork by spinnaker.

the class StackdriverWriterTest method testAddMeasurementsToTimeSeries.

    Measurement measureAXY = new Measurement(idAXY, millisA, 1);
    Measurement measureBXY = new Measurement(idBXY, millisB, 20.1);
    descriptorRegistrySpy.addExtraTimeSeriesLabel(MetricDescriptorCache.INSTANCE_LABEL, INSTANCE_ID);
    Assert.assertEquals(makeTimeSeries(descriptorA, idAXY, 1, timeA), writer.measurementToTimeSeries(descriptorA.getType(), testRegistry, timerA, measureAXY));
    Assert.assertEquals(makeTimeSeries(descriptorB, idBXY, 20.1, timeB), writer.measurementToTimeSeries(descriptorB.getType(), testRegistry, timerB, measureBXY));
