Query Explanation

The query computes, for each service, the percentage of requests returning a 5xx status code over the last 3 minutes (using rate to get a per‑second average, summing all 5xx codes, dividing by the total request rate, and multiplying by 100). The alert triggers when this error‑rate percentage exceeds 5 % for any service.
