如何配置Stagemonitor仅采集指定方法的指标，屏蔽不需要的方法？

Absolutely, you can filter out unwanted metrics in Stagemonitor so only your target methods' data shows up—perfect for your PetClinic testing scenario. Here are three reliable approaches to hide that /owners/test endpoint's metrics:

1. Use Stagemonitor's Built-in Configuration Filters (No Code Changes Needed) #

This is the simplest way if you don't want to modify your controller code. Just add exclusion rules to your configuration file (either stagemonitor.properties or Spring Boot's application.properties):

Exclude by HTTP Endpoint #

To block metrics for the /owners/test path specifically:

stagemonitor.instrument.http.exclude-paths=/owners/test

You can also use wildcards if you need to exclude multiple similar paths, like */test*.

Exclude by Java Method Signature #

If you want to target the exact testing method regardless of its endpoint mapping:

stagemonitor.instrument.method.exclude-methods=com.yourpackage.OwnerController.testing(java.util.Map)

Replace com.yourpackage.OwnerController with the actual full class path of your controller. Wildcards work here too—for example, *Controller.testing* would match any controller's testing method.

2. Mark the Method as Unmonitored with an Annotation #

Stagemonitor provides a @NotMonitored annotation that tells the agent to skip collecting metrics for the annotated method. Just add it directly to your test method:

@NotMonitored
@RequestMapping(value = "/owners/test", method = RequestMethod.GET)
public String testing(Map<String, Object> model) {
    Owner owner = new Owner();
    model.put("owner", owner);
    return VIEWS_OWNER_CREATE_OR_UPDATE_FORM;
}

This makes the exclusion explicit right in your code, which is great for clarity.

3. Custom Monitoring Interceptor (For Advanced Filtering) #

If you need more complex logic (like excluding methods based on dynamic conditions), you can create a custom interceptor to control what gets monitored:

import org.stagemonitor.core.monitor.MonitorInterceptor;
import org.stagemonitor.core.monitor.MonitorRequest;

public class CustomMetricFilter implements MonitorInterceptor {
    @Override
    public boolean preMonitor(MonitorRequest monitorRequest) {
        // Skip monitoring for the "testing" method
        return !monitorRequest.getMethodName().equals("testing");
    }
}

Then register this interceptor in your Stagemonitor configuration to activate it.

Verify the Fix #

After applying any of these changes, restart your PetClinic application, trigger the /owners/test endpoint, and check the Stagemonitor browser widget—you should no longer see metrics for that method, while your desired methods' data remains visible.
