Getting started with Business Metrics in PHP applications

Measuring & gathering infrastructure metrics is easy nowadays thanks to free tools like prometheus, grafana and a whole lot of exporters for servers, databases, redis, docker and so on. For sure those metrics are important for the reliable operation of your systems, but do they tell you, if your business is successful?
With a few examples I want to show you how to measure & monitor business relevant values from within your application(s) by introducing you to different PHP libraries that help you accomplish transparency of success factors. In the end I will show you how to set up a dashboard and alerts that even your manager(s) like and understand.
