Why are multi-window, multi-burn-rate alerts better than a single threshold? [Basic]
Answer
Multi-window, multi-burn-rate alerts are better because they catch fast, severe incidents quickly while avoiding noise from brief spikes. They also catch slow burns that would not page immediately but would still exhaust the error budget.
Technical explanation
A single threshold can be too noisy during short spikes or too slow during gradual degradation.
Pairing a short window with a longer confirmation window improves precision.
Common patterns include fast-burn pages and slow-burn tickets or lower-urgency alerts.
Hands-on example
Example: page when burn rate is greater than 14x for both 5 minutes and 1 hour. Create a ticket when burn rate is greater than 3x for both 30 minutes and 6 hours. This catches real budget threats without waking people for harmless one-minute blips.
