Dynatrace is the way to go

The way we use Dynatrace in our department is the following. We start early during development, we start monitoring and creating baselines for the system as a whole, then we use these baselines and compare them against the current state of the system after the feature is implemented. This helps us a lot to understand the behavior of our applications and how the feature behaves in relation to the baseline. This way we can further tweak the code or continue as it is.
