Module 1 · Observability basicsLesson 4 of 4

Goal: Confirm you can pick the right signal for a question and find it on a service.

Four questions: three on Module 1, one on Path 5, Module 7. Every answer explains itself, right or wrong.

Users say checkout was slow at about 10:00. Your app is one service. What's the best order to investigate?
Which of these is saturation?
You run a background worker. Where do you watch its error rate?
From Path 5: your app needs about three minutes to start, and every deploy restarts it before it's ready. What fixes it?

Retry as often as you like.
