Error budget = (1-SLO) × time. Burn rate = how fast you're consuming it.

What you're seeing

SLO 99.9% over 30 days = 43 minutes of error budget. Burn rate 1× = consuming budget at SLO's pace. 14× = consuming the month's budget in 2.5 days.

Multi-window alerts: fast (5min × 14×) catches spikes; slow (1hr × 6×) catches drifts. Two conditions ANDed reduces false positives.

★ KEY TAKEAWAY
Burn rate = how fast you're consuming the error budget. 14× = consuming the month in 2.5 days. Multi-window alerts catch real issues.
▶ WHAT TO TRY
  • Adjust error rate.
  • Watch error budget drop.
  • 14× burn rate is when alert fires in real production setups.
