Examples with PauseDetector io.micrometer.core.instrument.distribution.pause.PauseDetector used on opensource projects

Example 1 with PauseDetector

use of io.micrometer.core.instrument.distribution.pause.PauseDetector in project micrometer by micrometer-metrics.

the class MeterRegistryTest method histogramConfigTransformingMeterFilter.

@Test
void histogramConfigTransformingMeterFilter() {
    MeterRegistry registry = new SimpleMeterRegistry() {

        @Override
        protected Timer newTimer(@Nonnull Meter.Id id, DistributionStatisticConfig histogramConfig, PauseDetector pauseDetector) {
            assertThat(histogramConfig.isPublishingHistogram()).isTrue();
            return super.newTimer(id, histogramConfig, pauseDetector);
        }
    };
    registry.config().meterFilter(new MeterFilter() {

        @Override
        public DistributionStatisticConfig configure(Meter.Id mappedId, DistributionStatisticConfig config) {
            return DistributionStatisticConfig.builder().percentiles(0.95).percentilesHistogram(true).build().merge(config);
        }
    });
    registry.timer("my.timer");
}

Example 2 with PauseDetector

use of io.micrometer.core.instrument.distribution.pause.PauseDetector in project micrometer by micrometer-metrics.

the class AbstractTimer method initPauseDetector.

    pauseDetector.addListener((pauseLength, pauseEndTime) -> {
        // System.out.println("Pause of length " + (pauseLength / 1e6) + "ms, end time " + pauseEndTime);
        if (intervalEstimator != null) {
            long estimatedInterval = intervalEstimator.getEstimatedInterval(pauseEndTime);
