Controlling your race with Micrometer, Spring Boot (2.x) and Cloud Foundry

We're happy to announce that Ko Turk is going to be our next speaker for the DB JUG, Ko is working as a Senior Java Developer for Blue4IT and speaking regularly at international conferences about Micrometer and IDEs. A little more info about his talk:

Imagine that you’re part of a (car) race team. You’re the one behind the screens to control the race and make some tough decisions (like changing the teams strategy).

But you don’t have the insights (or metrics) about your car, opponents or even the weather. Sounds painful right? But why are we making this mistake when building our software? Why don’t we implement metrics by default?

SLFf4J logging is one side of the story, but we also need to know our application health. That’s where Micrometer comes in! It’s a library which you can use to define your own custom metrics, like:

• timers (to check the performance of your microservices)
• counters (to check how many times a certain event is occurring)
• gauges (to check the current value of a variable)
• and many more
  These metrics are exposed by REST endpoints (JSON) together with Spring Boot actuator, which can be saved into a database like Prometheus or Graphite. And to visualize the data you can use a tool like Grafana. Pretty interesting right?

In the demo (live coding!) I will show you how to create such applications using Micrometer, Spring Boot and Cloud Foundry as our platform. Ready to win this race with me? Jump in!
