slo-kit

Stop hand-rolling SLO alerts. Define SLOs as code and get correct multi-window burn-rate Prometheus alerts for free.

slo-kit turns raw Prometheus / OpenTelemetry metrics into:

• SLO definitions as code — SLI query + target + rolling window.
• Live error-budget & burn-rate tracking — consumed, remaining, time-to-exhaustion.
• Correct multi-window / multi-burn-rate Prometheus alert rules — per the Google SRE workbook.

SLO math is subtle and commonly implemented incorrectly. slo-kit packages it correctly and reusably.

Install

pip install slo-kit
# or
docker run --rm ghcr.io/slo-kit/slo-kit --help
