How to detect:

Service CPU usage exceeds 85% of allocated quota for 10 minutes, causing order processing latency to increase and customers to see slow checkouts.

Recommended action:

1. Check for runaway queries. 2. Scale HPA (Horizontal Pod Autoscaler). 3. Check recent deployments. Consult runbook for detailed steps.
