Free Prometheus Alert Rule and SLO Generator

Tools for Prometheus monitoring: SLO-based PromQL generator, error budget calculator, and scaling to avoid OOMs.

Brought to you by Cardinality Cloud, LLC.

Stop writing complex YAML by hand! Stop trying to figure out the math! Use this free tool to instantly generate production-ready Prometheus PromQL rules and calculate your error budget based on SLO best practices for reliability and availability. Create customer experience goals with multi-burn-rate, error budget based alerts that catch issues before they breach your SLO — just like Google SRE teams do. Learn more about SLO alerting.

Monitor what matters: user-facing reliability, not arbitrary thresholds.

The Easiest Way to Implement SLO Alerting

  • Automatically calculate your error budget and downtime (allowed downtime per month/year).
  • Generates compliant PromQL alert examples for both Availability and Latency SLOs.
  • Reduces alert fatigue and increases MTTR by generating highly reliable burn rate alerts.
