Before running this project, start a local Atlas server:
$ curl -Lo memory.conf https://raw.githubusercontent.com/Netflix/atlas/master/conf/memory.conf
$ curl -LO https://github.com/Netflix/atlas/releases/download/v1.4.5/atlas-1.4.5-standalone.jar
$ java -jar atlas-1.4.5-standalone.jar memory.conf
More information about interacting with the Atlas server can be found on the Atlas wiki.
Run the project as a Spring Boot app (e.g. import into IDE and run main method, or use "mvn spring-boot:run or gradle bootRun or ./gradlew bootRun"). It will start up on port 8080 and begin publishing a counter metric via Spectator every 5 seconds.
