Imagine that you’re part of a car racing 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? That’s where Micrometer comes in! It can help you with creating timers, gauges, counters and comparing data. We will create an application from scratch (lot of live coding)! Ready for the ride?!
