At my current project, we’ve been building three different applications. All three applications are based on Spring Boot but have very different workloads. They’ve all reached their way to the production environment and have been running steadily for quite some time now. We do regular (weekly basis) deployments of our applications to production with bug fixes, new features, and technical improvements. The organisation has a traditional infrastructure workflow in the sense that deployments to the VM instances on acceptance and production happen via the (remote hosting) provider.

The hosting provider is responsible for the uptime of the applications and therefore they keep an eye on system metrics through the usage of their own monitoring system. As a team, we are able to look in the system, but it doesn’t say much about the internals of our application. In the past, we’ve asked to add some additional metrics to their system, but the system isn’t that easy to configure with additional metrics. To us as a team runtime statistics about our applications and the impact our changes have on the overall health are crucial to understanding the impact of our work.
