Examples with RingbufferSlice com.hazelcast.internal.metrics.managementcenter.ConcurrentArrayRingbuffer.RingbufferSlice used on opensource projects

Example 1 with RingbufferSlice

use of com.hazelcast.internal.metrics.managementcenter.ConcurrentArrayRingbuffer.RingbufferSlice 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();
        MetricKeyConsumer metricConsumer = new MetricKeyConsumer();
        for (Map.Entry<Long, byte[]> entry : collections) {
            MetricsCompressor.extractMetrics(entry.getValue(), metricConsumer);
        }
        assertTrue(metricConsumer.mapMetric);
    });
}

Example 2 with RingbufferSlice

use of com.hazelcast.internal.metrics.managementcenter.ConcurrentArrayRingbuffer.RingbufferSlice in project hazelcast by hazelcast.

the class ReadMetricsOperation method run.

@Override
public void run() {
    ILogger logger = getNodeEngine().getLogger(getClass());
    MetricsService service = getService();
    CompletableFuture<RingbufferSlice<Entry<Long, byte[]>>> future = service.readMetrics(offset);
    future.whenCompleteAsync(withTryCatch(logger, (slice, error) -> doSendResponse(error != null ? peel(error) : slice)), CALLER_RUNS);
}

Example 3 with RingbufferSlice

use of com.hazelcast.internal.metrics.managementcenter.ConcurrentArrayRingbuffer.RingbufferSlice in project hazelcast by hazelcast.

the class MetricsServiceTest method readMetrics.

private void readMetrics(MetricsService metricsService, long sequence, MetricConsumer metricConsumer) throws InterruptedException, java.util.concurrent.ExecutionException {
    CompletableFuture<RingbufferSlice<Map.Entry<Long, byte[]>>> future = metricsService.readMetrics(sequence);
    RingbufferSlice<Map.Entry<Long, byte[]>> ringbufferSlice = future.get();
    MetricsResultSet metricsResultSet = new MetricsResultSet(ringbufferSlice.nextSequence(), ringbufferSlice.elements());
    metricsResultSet.collections().forEach(entry -> extractMetrics(entry.getValue(), metricConsumer));
