How do you identify the exact deployment that introduced an issue?
Core Summary
Put the deployment log and the metrics timeline side by side. A regression that started fifteen minutes ago was almost certainly caused by something that shipped in that window. Confirm which commit is actually running from the image digest, then roll back and watch whether the metrics recover, that is your proof.
Hints
Hint 1: Deployments and regressions are almost always correlated
Hint 2: Image digest or container commit hash is your proof
Hint 3: If metrics recover after rollback, you have your culprit
