Spring-Boot Execution

Requires ActiveMQ listening on tcp://localhost:61616

1. Build all the sub-projects - mvn clean install

• event-common
• event-test-harness
• event-ingestion
• event-auditing
• event-care-management
• event-cep

2. Start all Microservices - mvn spring-boot:run -Drun.arguments="-Xmx256m,-Xms128m"

• event-ingestion
• event-auditing
• event-care-management
• event-cep

3. Run Test Harness

cd event-test-harness/target

• java -Dactivemq.hostname=localhost -jar event-client-1.0.2.jar Leon

• java -Dactivemq.hostname=localhost -jar event-client-1.0.2.jar Roy

• java -Dactivemq.hostname=localhost -jar event-client-1.0.2.jar Eldon

or start JMeter and run test suite

..event-ingestion/src/test/jmeter/Camel Mock Publisher

4. View Results in ActiveMQ Console - http://localhost:8161/admin

default uid/pw = admin/admin

5. View Audit File Results

cd event-auditing/target/events
