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.
Page Load Regression
Raises warnings when page-load p95 rises above its service baseline and the good-speed threshold.
Web Vitals Regression
Raises warnings when a route’s LCP, INP or CLS p75 rises above its baseline and leaves the good range.
