Strongly disagree with this. I would rather have an excess of useless logs with the important ones than be missing the important logs. My motto is that so long

Strongly disagree with this. I would rather have an excess of useless logs with the important ones than be missing the important logs. My motto is that so long as the logs don't break your performance budget, log away. However, do take care to keep logs easily searchable and filterable. If needed, you can even have certain logs go to separate places so that you can have the most important logs in one place and more detailed logging in another. However, in that case it is usually best to have one set of logs be a superset of another to avoid needing to join across the logs.
