jolokia-jvm-hawkular

PoC to investigate whether its possible to extend the Jolokia JVM Agent to push data into Hawkular Metrics. The Jolokia Agent is embedded with collectors which collect and then send to Hawkular Metrics.

Build

hawkular-client-java

Since the version of the Hawkular Java Client i am using isn't currently released, you will need to build from source:

git clone -b metrics-19 https://github.com/garethahealy/hawkular-client-java.git
cd hawkular-client-java
mvn clean install -DskipTests

You can then build the rest of the project:

mvn clean install

Running Outside of OpenShift

Running example

The cdi-simple-jetty example is based on:

https://github.com/fabric8io/ipaas-quickstarts/tree/cc3eb91c365936e40b759d321974329167073bc3/archetypes/cdi-camel-http-client-archetype 

Once it is built, you can run the example by:

cd cdi-simple-jetty/target/hawt-app/bin
./run.sh

You can then go to:

http://localhost:8080/camel/hello?name=bob

Running Hawkular Metrics

To run hawkular metrics, you can use the following repo, which contains all the needed Dockerfiles:

git clone https://github.com/garethahealy/hawkular-aio-docker.git
docker-compose up

Running Inside of OpenShift

Running example

I am using the CDK for development. If you haven't used that before, check out the below:

https://blog.openshift.com/how-to-install-red-hat-container-development-kit-cdk-in-minutes/

Once the CDK if up and running, you'll need to deploy a nexus as we need to deploy the hawkular-client and agent as they are currently snapshots.
