Design burn rate alerts that do not wake people up for sport

How to build steadier SLO alerts when metrics, labels, and rule behavior keep shifting underneath you.

Recent Prometheus, OpenTelemetry Collector, Loki, and Alloy releases all point to the same uncomfortable truth: alerts wired straight to raw metrics and fragile labels become noisy or broken very easily. This guide shows how to anchor burn-rate alerts on stable recording rules, validate them with promtool, and roll them out without turning every short spike into a fake emergency.

Check rule syntax

promtool check rules rules/slo-burn-alerts.yaml

Inspect the service error ratio

curl -sG http://prometheus:9090/api/v1/query --data-urlencode 'query=job:slo_error_ratio:rate5m{job="api"}' | jq .

Review the fast burn rate before enabling paging

curl -sG http://prometheus:9090/api/v1/query --data-urlencode 'query=job:slo_error_budget_burn_rate_1h{job="api"}' | jq .
