Prometheus

Prometheus is a Cloud Native monitoring application.

To instrument our Java code we need to manipulate the metrics each time a new HTTP request is received.

See the application for more details.

As an added bonus, Prometheus is able to scrape the Spring Boot Actuactor metrics for free!
