Examples with ServerMonitorListener com.mongodb.event.ServerMonitorListener used on opensource projects

Example 1 with ServerMonitorListener

use of com.mongodb.event.ServerMonitorListener in project mongo-java-driver by mongodb.

the class ServerDiscoveryAndMonitoringProseTests method testHeartbeatFrequency.

@Test
@SuppressWarnings("try")
public void testHeartbeatFrequency() throws InterruptedException {
    assumeFalse(isServerlessTest());
    CountDownLatch latch = new CountDownLatch(5);
    MongoClientSettings settings = getMongoClientSettingsBuilder().applyToServerSettings(new Block<ServerSettings.Builder>() {

        @Override
        public void apply(final ServerSettings.Builder builder) {
            builder.heartbeatFrequency(50, TimeUnit.MILLISECONDS);
            builder.addServerMonitorListener(new ServerMonitorListener() {

                @Override
                public void serverHeartbeatSucceeded(final ServerHeartbeatSucceededEvent event) {
                    latch.countDown();
                }
            });
        }
    }).build();
    try (MongoClient ignored = MongoClients.create(settings)) {
        assertTrue("Took longer than expected to reach expected number of hearbeats", latch.await(500, TimeUnit.MILLISECONDS));
