For Wicket 1.4 support, see the wicket-1.4 branch
Wicket is a great Java web application framework. New Relic is a great web application monitoring too. Two great tastes that taste great together.
This project aims to improve the New Relic/Wicket experience by enhancing the information provided to New Relic about your application. Currently it does this in three ways:
- Set a useful New Relic transaction name for each request.
- Send RuntimeExceptions to New Relic as errors.
- Provide ready-made Label components to enable New Relic's Real User Monitoring feature.
This library provides an IRequestCycleListener that sends per-request data to New Relic. To use this, add an instance of NewRelicRequestCycleListener in your WebApplication subclass init() method. Like so:
public class MyApplication extends WebApplication {
@Override
public void init() {
super.init();
getRequestCycleListeners().add(
new NewRelicRequestCycleListener("com.example.package."));
}
}If your application supports user logins, you may want to implement NewRelicSessionSupport in your Session subclass. Doing so allows you to associate a username and account name with each request which enhances the information gathered by Real User Monitoring.
New Relic's Real User Monitoring works by running a bit of JavaScript at the top of the page and then another bit of JavaScript just before the end of the page. The JavaScript is generated dynamically by the New Relic agent. The NewRelicLabels class has factory methods that generate Wicket labels to output the New Relic JavaScript.
To use these labels, add a <wicket:container> element with an ID of newRelicBrowserTimingHeader to the <head> element just after any <meta> tags. Add another <wicket:container> element with an ID of newRelicBrowserTimingFooter just before the closing </body> tag. Then, simply add the Labels returned from NewRelicLabels.browserTimingHeaderLabel() and NewRelicLabels.browserTimingFooterLabel() to your page.
Example:
MyPage.html:
<html>
<head>
<wicket:container wicket:id="newRelicBrowserTimingHeader"></wicket:container>
</head>
<body>
<!-- Awesome page content goes here... -->
<wicket:container wicket:id="newRelicBrowserTimingFooter"></wicket:container>
</body>
</html>MyPage.java:
public class MyPage extends WebPage {
public MyPage() {
add(NewRelicLabels.browserTimingHeaderLabel());
add(NewRelicLabels.browserTimingFooterLabel());
}
}
