Examples with TaggedMetricsServiceInvocationEventHandler com.palantir.tritium.event.metrics.TaggedMetricsServiceInvocationEventHandler used on opensource projects

Example 1 with TaggedMetricsServiceInvocationEventHandler

use of com.palantir.tritium.event.metrics.TaggedMetricsServiceInvocationEventHandler in project tritium by palantir.

the class InstrumentationBuilder method withTaggedMetrics.

/**
 * Supplies a TaggedMetricRegistry and a name prefix to be used across service invocations.
 *
 * <p>Uses a {@link TaggedMetricsServiceInvocationEventHandler} object for handling invocations, so metric names
 * are chosen based off of the interface name and invoked method.
 *
 * @param metricRegistry - TaggedMetricsRegistry used for this application.
 * @param prefix - Metrics name prefix to be used
 * @return - InstrumentationBuilder
 */
public InstrumentationBuilder<T, U> withTaggedMetrics(TaggedMetricRegistry metricRegistry, @Nullable String prefix) {
    checkNotNull(metricRegistry, "metricRegistry");
    String serviceName = prefix == null || prefix.isEmpty() ? interfaceClass.getName() : prefix;
    return withHandler(new TaggedMetricsServiceInvocationEventHandler(metricRegistry, serviceName));
}

Example 2 with TaggedMetricsServiceInvocationEventHandler

use of com.palantir.tritium.event.metrics.TaggedMetricsServiceInvocationEventHandler in project tritium by palantir.

the class InstrumentationTest method testStackDepth_notFunctionOfHandlers.

@Test
void testStackDepth_notFunctionOfHandlers() {
    StackTraceSupplier stackTraceSupplier = () -> cleanStackTrace(new Exception().getStackTrace());
    StackTraceSupplier singleHandlerInstrumentedStackSupplier = Instrumentation.builder(StackTraceSupplier.class, stackTraceSupplier).withHandler(new TaggedMetricsServiceInvocationEventHandler(new DefaultTaggedMetricRegistry(), "test0")).build();

    StackTraceElement[] singleHandlerInstrumentedStackTrace = singleHandlerInstrumentedStackSupplier.get();
    StackTraceElement[] multipleHandlerInstrumentedStack = multipleHandlerInstrumentedStackSupplier.get();
    // Tritium frames should not scale with the number of registered InvocationEventHandler instances.
    assertThat(singleHandlerInstrumentedStackTrace).hasSameSizeAs(multipleHandlerInstrumentedStack);
