Collect metrics in a JAX RS application and report to Graphite.

pub-metrics

Example project to count requests in a JAX RS application with dropwizard-metrics and report them to Graphite for visualization.

Graphite setup

Start Graphite via the recommended docker image. I had to add the portmapping 8081:8080 to access the dashboard:

docker run -d\  
 --name graphite\  
 --restart=always\      
 -p 80:80\
 -p 8081:8080\  
 -p 2003-2004:2003-2004\
 -p 2023-2024:2023-2024\
 -p 8125:8125/udp\
 -p 8126:8126\
 graphiteapp/graphite-statsd

Run pub application

Build the application with Maven:

mvn package

Run the war file with the lates version of Payara Micro (https://www.payara.fish/downloads). Specify the Graphite server with environment args:

java -Dgraphite.url=192.168.99.100\
     -Dgraphite.port=2003\
     -jar payara-micro-5.181.jar\
     --deploy pub-metrics-1.0-SNAPSHOT.war
