Symptom Log
manual_check_fail.log
[WARNING] Checking error budget for API-Gateway...
[INFO] 42% consumed in 30 days.
# Error: Missed 25% spike in the last hour because static check only runs daily.A burn rate tells you how fast you're consuming your error budget relative to your SLO window. A burn rate of 1x means you'll exhaust your budget exactly at the end of the window.
Manual monitoring often misses high-velocity spikes until it's too late to recover.
Fix: Multi-Window Alerts
Configure Watch.dog Burn Alerts with multiple time windows (e.g., 1h and 6h) to detect both spikes and slow leaks.
