wicket-metrics

Painless way of adding JMX metrics to your Wicket project.

Usage

Start by addding the following Maven dependency:

<dependency>
    <groupId>com.nitorcreations</groupId>
    <artifactId>wicket-metrics</artifactId>
    <version>1.0</version>
</dependency>

After this, three types of metrics can be added:

1. Page size

• This will show the size (min, max, avg, etc) of each rendered page in your web app

2. Render time

• This will show the time (min, max, avg, etc) it too your server the render the given page

3. Session size

• This is a single metric that tracks the size of your Wicket session

For Page size (1) and Render time (2), example code would look something like this:

/**
 * A common base page for all your pages.
 */
public abstract class BasePage extends WebPage {

...

    @Override
    protected void onInitialize() {
        super.onInitialize();
    
        add(new PageSizeHistogramBehavior());   // (1)
        add(new TimingBehavior());              // (2)
    }
}

For the session size metric, you need to add this to your WebApplication:

public class MyApplication extends WebApplication {

    @Override
    public void init() {
        super.init();

        getRequestCycleListeners().add(new SessionSizeHistogramRequestCycleListener());
    }
}
