| 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. |
