What does node-loop-detective actually track in Node.js?

It instruments I/O ops like HTTP, DNS, DB – now fetch() and dns.promises too. Catches slow calls invisible to basic patches.

How do I track fetch() calls in Node.js monitoring ?

Drop node-loop-detective v1.5.0. Auto-patches global fetch, logs slow ones with stacks. No code changes.

Why is my Node.js app slow but metrics look fine?

Likely fetch() or dns.promises bypassing old trackers. Update your instrumentation – loop-detective fixes it.
