Anomaly Detection

Multi-modal baselines detect what's out of pattern across metrics, logs, traces, and business KPIs, with no thresholds to babysit per service. Every score is explainable: z-score, changepoint, seasonal residual, or KPI-drift, plus the exact window it fired on.

Schema change added a non-covering index on tx_events(tenant_id, created_at), degrading tail latency on the checkout write path. Error ratio trails deploy by 2m35s across 4 cited signals.

FIELD NOTE · DESIGN PARTNER

“The RCA agent surfaced the deploy-related root cause on INC-4471 before I finished loading the second Grafana tab. That’s the honest headline — every alert I’ve triaged since has felt like a downgrade.”
