Is there a way to know how many requests are currently being served?

Hi.. I am asking this because I need to shutdown some pubsub queues only after all requests being served are completed (Some request might consume or produce messages). Right now I implemented a filter to count those requests and here is its code:

public class CurrentRequestCountFilter implements ContainerRequestFilter, ContainerResponseFilter {

private final AtomicInteger currentRequestCount;

@Inject
public CurrentRequestCountFilter(AtomicInteger currentRequestCount) {
    this.currentRequestCount = currentRequestCount;
}

public void filter(ContainerRequestContext containerRequestContext) {
    int currentCount = currentRequestCount.incrementAndGet();
}

@Override
public void filter(
        ContainerRequestContext containerRequestContext,
        ContainerResponseContext containerResponseContext) {
    int currentCount = currentRequestCount.decrementAndGet();
}

}

Hi @emad-jamal. You can use the Dropwizard Metrics project for that.

The metrics for Jetty provide a Counter for the active requests.
