عرض عملي: لوحة SLO وتنبيه burn-rate لعملية الدفع

خطوة بخطوة

1. Define the SLI from the gateway metrics: checkout requests with status < 500, valid excluding 4xx.
2. Add recording rules for the ratio over 5 m, 1 h, and 30 d.
3. Build the dashboard: SLO, remaining budget, burn rate.
4. Planned mistake: measure the SLI only inside orders; requests failing at the gateway are missing. Move the measurement to the gateway.
5. Add the two-window burn-rate alerts with runbook links.
6. Inject errors and watch the alert fire.
