CloudWatchMetricObserver not pushing metrics to CloudWatch

[sobel003]

I followed the little documentation out there for using CloudWatchMetricObserver but I can't see my hystrix metrics pushed into CloudWatch. I'm pretty sure I may be missing something but not sure what it can be. This is my code;

@Configuration
@Profile("aws")
public class CloudWatchMetricsConfiguration {

    
    private static final Logger LOGGER = LoggerFactory.getLogger(CloudWatchMetricsConfiguration.class);
    
    private static final int MAGIC_NUMBER_FIVE = 5;
    
    /**
     * Init method.
     */
    @PostConstruct
    public void init() {

        try{
            
            HystrixPlugins.getInstance().registerMetricsPublisher(HystrixServoMetricsPublisher.getInstance());
            
            LOGGER.info("HystrixServoMetricsPublisher registered.");
            
            CloudWatchMetricObserver cloudwatchObserver = new CloudWatchMetricObserver(
                    "cloudwatchObserver", "EVAS_", InstanceProfileCredentialsProvider.getInstance());
            MetricObserver transform = new CounterToRateMetricTransform(
                    cloudwatchObserver, 1, TimeUnit.MINUTES);

            if (!PollScheduler.getInstance().isStarted()) {
                LOGGER.info("PollScheduler not started. Starting it...");
                PollScheduler.getInstance().start();
                LOGGER.info("PollScheduler started.");
            }
            PollRunnable registeryTask = new PollRunnable(new MonitorRegistryMetricPoller(), BasicMetricFilter.MATCH_ALL, cloudwatchObserver, transform); 
            PollScheduler.getInstance().addPoller(registeryTask, MAGIC_NUMBER_FIVE, TimeUnit.SECONDS); 
            
        } catch (Exception e) {
            LOGGER.error("Error setting up Cloudwatch metric publishing mechanism: {}.", e.getMessage(), e);

        }
 
        
        
    }

I can see the logs saying that the PollScheduler started and there is no error thrown and yet I can't find the metrics.

Is there anything else I should do?

Have you tried attaching a debugger while forcing a metric?

[sobel003]

It is solved now. Actually yes, the debugger was showing that the metrics were being sent but we couldn't see them in AWS and the cause is that they were being sent to the default region instead of the one we were testing on. Changing the way we created the CloudWatchMetricObserver solved the issue by picking up the region where the application is running.

Thanks for the reply.

Glad you worked it out.
