com.codahale.metrics.Gauges in spring boot application

Question

I would like to add metrics to track the size of number of operations and number of sites, which are stored in values in a service:

import java.util.concurrent.atomic.AtomicInteger;

import org.springframework.stereotype.Service;

@Service
public class TrackerService {

    private final AtomicInteger sitesInProgress  = new AtomicInteger(0);
    private static AtomicInteger amountOfExecutingOperations = new AtomicInteger(0);

    public AtomicInteger getSitesInProgress() {
        return sitesInProgress;
    }
    
    public static AtomicInteger getAmountOfExecutingOperations() {
        return amountOfExecutingOperations;
    }
}

Is it enough just create a service like that in order to be able to track these values?

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import com.codahale.metrics.MetricRegistry;

@Service
public class GaugeMetricService {
    
    @Autowired
    public GaugeMetricService(final MetricRegistry metricRegistry, final TrackerService trackerService) {
        metricRegistry.gauge(MetricRegistry.name("tracker", "sitesInProgress"), () -> () -> trackerServicerackerService.getSitesInProgress());
        metricRegistry.gauge(MetricRegistry.name("deviceoperationtracker", "numberOfExecutingOperations"), () -> () -> trackerServicerackerService.getAmountOfExecutingOperations());
    }

}

Thanks in advance!
