伺服monito注释是否可以直接使用？

Question

I have write a method like that:

@Scheduled(fixedDelay = 10_000)
@Monitor(name = "componentMonitor", type = DataSourceType.COUNTER)
public int method() {
    log.info("ping");
    return RandomUtils.nextInt();
}

It is invocated and ping appears in console, but componentMonitor do not appears into /metrics this metric is not send to org.springframework.boot.actuate.autoconfigure.ExportMetricReader . So how configurated servo/spectacor to make @Monitor annotations work?

Note

Reporting other metric via com.netflix.spectator.api.Registry works. So generally metric reporting and servo itself work.

Answer 1

No, it doesn't. I think you can use Monitors.newObjectMonitor(id, object) to get it to work. There is no aspect or anything to auto-create the Monitor .

Answer 2

It's my understanding that you need to register a MonitorRegistryMetricPoller for the @Monitor to work:

private void schedule(MetricPoller poller, List<MetricObserver> observers) {
    final PollRunnable task = new PollRunnable(poller, BasicMetricFilter.MATCH_ALL,
            true, observers);
    PollScheduler.getInstance().addPoller(task, 1, TimeUnit.MINUTES);
}

private void initMetricsPublishing() {
    final List<MetricObserver> observers = new ArrayList<>();

    final AmazonCloudWatchClient cloudWatchClient =
            new AmazonCloudWatchClient(awsCredentials);
    cloudWatchClient.setEndpoint(String.format("monitoring.%s.amazonaws.com", REGION));
    AwsTaggingCloudWatchMetricObserver cloudWatchMetricObserver = new AwsTaggingCloudWatchMetricObserver("cloudwatch",
            "Nomp", cloudWatchClient);
    observers.add(cloudWatchMetricObserver);
    PollScheduler.getInstance().start();
    schedule(new MonitorRegistryMetricPoller(), observers);  // <--- this
    schedule(new JvmMetricPoller(), observers);
    schedule(new TomcatPoller(), observers);
}
