Sessie 1
18:45 - 19:30
Own your software by using Micrometer and Spring Boot
Abstract
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 team’s 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 own our software by adding those insights (or 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 that 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, and Spring Boot.Ready to win this race with me? Jump in!

Gradle: back to basics
Many developers (in my area of expertise) started using Gradle because they had to, especially in Android development, since Gradle is the build tool of choice. Many know how to do certain things in Gradle, but often without really knowing how it works under the hood. I’m going to try to change that, step by step. Let’s get back to the basics of Gradle. Especially useful for Android developers, but definitely not only for Android developers!
