Examples with COUNT com.hazelcast.internal.metrics.ProbeUnit.COUNT used on opensource projects

Example 1 with COUNT

use of com.hazelcast.internal.metrics.ProbeUnit.COUNT in project hazelcast by hazelcast.

the class LongGaugeImplTest method whenCacheDynamicMetricValueReplacedWithCachedMetricSource.

@Test
public void whenCacheDynamicMetricValueReplacedWithCachedMetricSource() {
    LongGaugeImpl longGauge = metricsRegistry.newLongGauge("foo.longField");
    // provide concrete value
    DynamicMetricsProvider concreteProvider = (descriptor, context) -> context.collect(descriptor.withPrefix("foo"), "longField", INFO, COUNT, 142);
    metricsRegistry.registerDynamicMetricsProvider(concreteProvider);
    // needed to collect dynamic metrics and update the gauge created from them
    metricsRegistry.collect(mock(MetricsCollector.class));
    assertEquals(142, longGauge.read());
    metricsRegistry.deregisterDynamicMetricsProvider(concreteProvider);
    // provide metric source to be cached
    SomeObject someObject = new SomeObject();
    someObject.longField = 42;
    metricsRegistry.registerDynamicMetricsProvider(someObject);
    // needed to collect dynamic metrics and update the gauge created from them
    metricsRegistry.collect(mock(MetricsCollector.class));
    assertEquals(42, longGauge.read());
}

Example 2 with COUNT

use of com.hazelcast.internal.metrics.ProbeUnit.COUNT in project hazelcast by hazelcast.

    DynamicMetricsProvider concreteProvider = (descriptor, context) -> context.collect(descriptor.withPrefix("foo"), "longField", INFO, COUNT, 42);
    metricsRegistry.registerDynamicMetricsProvider(concreteProvider);
    LongGaugeImpl longGauge = metricsRegistry.newLongGauge("foo.longField");
    // needed to collect dynamic metrics and update the gauge created from them
    metricsRegistry.collect(mock(MetricsCollector.class));
    assertEquals(42, longGauge.read());
    // clears the cached metric source
    metricsRegistry.deregisterDynamicMetricsProvider(concreteProvider);
