Examples with CapturingCollector com.hazelcast.internal.metrics.impl.CapturingCollector used on opensource projects

Example 1 with CapturingCollector

use of com.hazelcast.internal.metrics.impl.CapturingCollector in project hazelcast by hazelcast.

the class TcpServerConnectionManagerMetricsTest method testUnifiedEndpointManagerMetricsCollectedOnce.

@Test
public void testUnifiedEndpointManagerMetricsCollectedOnce() {
    CapturingCollector collector = new CapturingCollector();
    HazelcastInstance instance = createHazelcastInstance();
    getNodeEngineImpl(instance).getMetricsRegistry().collect(collector);
    // defined by ServerEndpointManager
    verifyCollectedOnce(collector, metricDescriptor(TCP_PREFIX_CONNECTION, "count"));
    // defined by ServerUnifiedEndpointManager
    verifyCollectedOnce(collector, metricDescriptor(TCP_PREFIX_CONNECTION, "clientCount"));
    verifyCollectedOnce(collector, metricDescriptor(TCP_PREFIX_CONNECTION, "textCount"));
}

Example 2 with CapturingCollector

use of com.hazelcast.internal.metrics.impl.CapturingCollector in project hazelcast by hazelcast.

the class TcpMetricValuesTest method test.

private void test(String... members) {
    int timeoutSecs = 10;
    // start 3 member cluster
    final HazelcastInstance hz1 = Hazelcast.newHazelcastInstance(getConfig(members));
    final HazelcastInstance hz2 = Hazelcast.newHazelcastInstance(getConfig(members));
