How do you approach debugging complex issues in production?

I start by gathering detailed logs and metrics to understand the problem scope and potential causes. Then I methodically isolate variables, reproduce the issue in a test environment if possible, and use debugging tools to trace the root cause.

Absolutely start with logging and metrics to pinpoint the problem area. Also consider setting up alerts and monitoring to catch issues early. Worst case, rolling back to a previous stable version can help stop the bleeding while you investigate further. Debugging in prod is tough but having a systematic approach and the right tooling is key.
