We had to make certain choices and decisions to make codebeat as sufficient in reporting issues as possible. However, we can only suggest changes; we cannot force you to implement them.
That is why, we allow our users to MUTE ISSUES on their end. You can both completely turn the notifications off or you can adjust the metrics to your liking.
You can learn more about muting issues in our documentation.
If you want to learn more about our metrics, here's a brief description of how does codebeat work.
