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.
