4 years ago Yep, turns out I can implement this in ~30 lines of code :)

Implement a special handler type which will escalate any logs over a certain threshold to errors. This is useful for testing if your goal is to avoid introducing any extra warning noise to a production system (e.g., run the system under normal conditions and ensure that it doesn't produce any warnings).
