Example 1 with LockService

use of com.hazelcast.cp.internal.datastructures.lock.LockService in project hazelcast by hazelcast.

the class CPSubsystemInfoCollector method forEachMetric.

@Override
public void forEachMetric(Node node, BiConsumer<PhoneHomeMetrics, String> metricsConsumer) {
    int cpMemberCount = node.getNodeEngine().getConfig().getCPSubsystemConfig().getCPMemberCount();
    boolean cpSubsystemEnabled = cpMemberCount != 0;
    metricsConsumer.accept(PhoneHomeMetrics.CP_SUBSYSTEM_ENABLED, String.valueOf(cpSubsystemEnabled));
    if (cpSubsystemEnabled) {
        metricsConsumer.accept(PhoneHomeMetrics.CP_MEMBERS_COUNT, String.valueOf(cpMemberCount));
        RaftService raftService = node.getNodeEngine().getService(RaftService.SERVICE_NAME);
        int groupsCount = raftService.getMetadataGroupManager().getGroupIds().size();
        metricsConsumer.accept(PhoneHomeMetrics.CP_GROUPS_COUNT, String.valueOf(groupsCount));
        SemaphoreService semaphoreService = node.getNodeEngine().getService(SemaphoreService.SERVICE_NAME);
        int semaphoresCount = semaphoreService.getTotalResourcesCount();
        metricsConsumer.accept(PhoneHomeMetrics.CP_SEMAPHORES_COUNT, String.valueOf(semaphoresCount));
        CountDownLatchService clService = node.getNodeEngine().getService(CountDownLatchService.SERVICE_NAME);
        int clCount = clService.getTotalResourcesCount();
        metricsConsumer.accept(PhoneHomeMetrics.CP_COUNTDOWN_LATCHES_COUNT, String.valueOf(clCount));
        LockService lockService = node.getNodeEngine().getService(LockService.SERVICE_NAME);
        int locksCount = lockService.getTotalResourcesCount();
        metricsConsumer.accept(PhoneHomeMetrics.CP_FENCED_LOCKS_COUNT, String.valueOf(locksCount));
        AtomicLongService atomicLongService = node.getNodeEngine().getService(AtomicLongService.SERVICE_NAME);
        int atomicLongsCount = atomicLongService.getAtomicValuesCount();
        metricsConsumer.accept(PhoneHomeMetrics.CP_ATOMIC_LONGS_COUNT, String.valueOf(atomicLongsCount));
        AtomicRefService atomicRefService = node.getNodeEngine().getService(AtomicRefService.SERVICE_NAME);
        int atomicRefsCount = atomicRefService.getAtomicValuesCount();
        metricsConsumer.accept(PhoneHomeMetrics.CP_ATOMIC_REFS_COUNT, String.valueOf(atomicRefsCount));
    }
}

Example 2 with LockService

use of com.hazelcast.cp.internal.datastructures.lock.LockService in project hazelcast by hazelcast.

    LockService service = getService();
    LockInvocationKey key = new LockInvocationKey(commitIndex, invocationUid, callerAddress, callId, getLockEndpoint());
    AcquireResult result = service.acquire(groupId, name, key, timeoutMs);
    if (result.status() == WAIT_KEY_ADDED) {
        return PostponedResponse.INSTANCE;
    }
    // SUCCESSFUL or FAILED
    return result.fence();
}
