Camel Spring Boot Metrics Example

Introduction

This example sends Camel route metrics to Graphite from a Spring Boot app.

Please read Configuration first

Build

You will need to compile this example first:

mvn install

Run

To run the example type

java -jar target/camel-example-spring-boot-metrics.jar

You will see logging from the 'Fast' and 'Slow' routes, and metrics will be sent to Graphite (or nc) every 5 seconds.

Configuration

Spring Boot auto-configures the com.codahale.metrics.MetricRegistry. See code comments in Application.java for further details.

If you already have a Graphite server, make sure that UDP is enabled (set ENABLE_UDP_LISTENER = True in carbon.conf).

If Graphite is not on your local machine, replace localhost in Application.java with the hostname or IP address of your Graphite server.

If you want to use TCP instead of UDP, use com.codahale.metrics.graphite.Graphite instead of com.codahale.metrics.graphite.GraphiteUDP, as shown here: http://metrics.dropwizard.io/3.1.0/manual/graphite/

If you can’t be bothered to set up a Graphite server right now, you can simulate it by running nc -ul 2003 on Linux. If you don’t have nc, use yum search netcat to find a suitable package to install (e.g. nmap-ncat.x86_64).
