Alert Threshold Best Practices

Good alert thresholds balance fast detection with a manageable on-call experience so your team responds quickly without burning out.

Understanding false positives vs missed incidents

Too-sensitive thresholds create noise and fatigue, while too-loose thresholds can delay detection. Aim for a middle ground and adjust over time.

Choosing sensible defaults

Start with conservative defaults for new services, then tune thresholds based on how critical each service is and how often it changes.

Adjusting over time

After each incident or noisy alert, review what happened and tweak thresholds, intervals, or escalation rules to improve signal quality.

Examples by use case

Different services justify different thresholds. Mission-critical APIs may need fast, strict thresholds, while internal tools can tolerate more variation.
