Module 14 · Chapter 13: Troubleshooting production
Troubleshooting production
In short
Start from outside like a user, then go in layer by layer. Suspect caches storing errors, host memory, changed host keys and flags that never arrive. Close with an incident note.
After this lesson you can
- Check production from outside, the way users see it
- Recognise common causes: caches, memory, host keys, switches that never arrive
- Write a short incident note once the problem is solved
