This chapter is an outline. The curriculum, learning objectives and
structure are settled; the prose, diagrams and code are still being written.
What is below is the plan for the chapter, not the chapter.
SQS — Troubleshooting Cheat Sheet
Read time: scan
Symptom → what to check → likely causes → fix. The full table from Module 26, condensed.
Planned contents
- The master symptom table (20+ rows)
- The metric-signature table
- The triage flowchart
- Emergency levers and their side effects
- Commands: queue attributes, metric snapshot, DLQ sample
- What not to do under pressure
Design rules for this sheet
- Tables, diagrams and bullets. Prose only where a sentence genuinely beats a row
- Scannable at a glance; printable on a laptop screen
- Every quota and price links to
_reference/aws-facts.md - It answers "remind me", not "teach me" — the course body does the teaching
