Updated Oct 24, 2026 · today

Raises warnings when a route’s LCP, INP or CLS p75 rises above its baseline and leaves the good range.

Example alert

Warning: LCP regression on /checkout — p75 reached 3800ms from a 1800ms baseline.

Exact wording varies — the detector generates titles from the anomaly it finds. This is representative of what an alert looks like when it fires.

Golden Signal Monitoring
Latency, saturation, and per-service error rate. Three of the four SRE golden signals — traffic is covered by Volume Anomaly.
SLO Monitoring
Error budget tracking with burn rate prediction. Get warned before the SLO breaches, not after.
Browser API Error Rate
Raises warnings when the share of failed browser API calls to a service rises above its baseline.
Error Session Rate
Raises warnings when the share of sessions with errors or rage-clicks rises above the baseline for that hour and day.
Page Load Regression
Raises warnings when page-load p95 rises above its service baseline and the good-speed threshold.
