Example 1 with ReadMetricsOperation

use of com.hazelcast.internal.metrics.managementcenter.ReadMetricsOperation in project hazelcast by hazelcast.

the class ReadMetricsOperationTest method testMetricsPresent_map.

@Test
public void testMetricsPresent_map() {
    Config config = new Config();
    HazelcastInstance hzInstance = createHazelcastInstance(config);
    IMap<Object, Object> map = hzInstance.getMap("map");
    map.put("key", "value");
    NodeEngineImpl nodeEngine = getNode(hzInstance).getNodeEngine();
    OperationServiceImpl operationService = nodeEngine.getOperationService();
    AtomicLong nextSequence = new AtomicLong();
    assertTrueEventually(() -> {
        long sequence = nextSequence.get();
        ReadMetricsOperation readMetricsOperation = new ReadMetricsOperation(sequence);
        InternalCompletableFuture<RingbufferSlice<Map.Entry<Long, byte[]>>> future = operationService.invokeOnTarget(MetricsService.SERVICE_NAME, readMetricsOperation, nodeEngine.getThisAddress());
        RingbufferSlice<Map.Entry<Long, byte[]>> ringbufferSlice = future.get();
        MetricsResultSet metricsResultSet = new MetricsResultSet(ringbufferSlice.nextSequence(), ringbufferSlice.elements());
        nextSequence.set(metricsResultSet.nextSequence());
        boolean mapMetric = false;
        List<Map.Entry<Long, byte[]>> collections = metricsResultSet.collections();
