To visualize the metrics with Graphite a little additional configuration is required:

(1) Add the additional maven dependency to your project:
[source,java]
----
<dependency>
	<groupId>io.dropwizard.metrics</groupId>
	<artifactId>metrics-graphite</artifactId>
	<version>${metrics.graphite.version}</version>
</dependency>
----

* the metrics.graphite.version should be the same as the metrics version of the wicket-metrics dependency. Check the Maven dependencies to ensure
this.

(2) Add the following code to your Application's init method:
[source,java]
----
	private GraphiteReporter reporter;
	
	@Override
	protected void init()
	{
		MetricRegistry metricRegistry = WicketMetrics.getMetricRegistry();
		final Graphite graphite = new Graphite(new InetSocketAddress("127.0.0.1", 2003));
		reporter = GraphiteReporter.forRegistry(metricRegistry).prefixedWith("WebApplications")
			.convertRatesTo(TimeUnit.SECONDS).convertDurationsTo(TimeUnit.MILLISECONDS)
			.filter(MetricFilter.ALL).build(graphite);
		
		// Collects data every 5 seconds
		reporter.start(5, TimeUnit.SECONDS);
	}

	@Override
	protected void onDestroy()
	{
		super.onDestroy();
		reporter.stop();
	}
----

(3) Install and setup graphite on your system. Example installation for Mac (beware that this is only a quickstart setup!):

- (1) Install homebrew:  http://brew.sh/[brew] 
- (2) Install  https://git-scm.com/[Git] 

- (3) brew install python

- (4) brew install cairo

- (5) brew install py2cairo

- (6) pip install Django==1.5

- (7) pip install "django-tagging<0.4"
- (8) sudo pip install carbon

- (9) pip install whisper

- (10) sudo pip install graphite-web

- (11) sudo pip install Twisted==11.1.0 

- (12) sudo chown -R <your username>:staff /opt/graphite

- (13) cp /opt/graphite/conf/carbon.conf{.example,}

- (14) cp /opt/graphite/conf/storage-schemas.conf{.example,}

- (15) cd /opt/graphite/webapp/graphite

- (16) cp local_settings.py{.example,}

- (17) python manage.py syncdb

- (18) python /opt/graphite/bin/carbon-cache.py start

- (19) python /opt/graphite/bin/run-graphite-devel-server.py /opt/graphite

- (20) Go to http://localhost:8080

* (18) and (19) have to be executed if the mac has been restarted 

(4) Now start your tomcat server configured like mentioned in the previous chapter.
