每个指标的预测带、BOCPD 变点、多变量。
What you get
- Per-metric, per-signature forecast band (Prophet baseline, ETSformer for high-cardinality)
- Change-point detection (BOCPD) on every metric — surfaces structural shifts
- Multi-variate anomaly: 'CPU is fine, IOPS is fine, but their joint distribution is wrong'
- Tunable sensitivity per workload (alerts on day-to-day vs. month-to-month deviations)
- First-class support for seasonality (daily, weekly, business-day)
- Built-in feedback loop: thumbs-up / thumbs-down trains the per-tenant model
vs Datadog DBM
FAQ
How long until the model is useful?+
We have a useful baseline at 3 days, an excellent one at 14 days. Until then we fall back to robust EWMA so you still get alerts.
Can I bring my own model?+
Business+ plans expose a webhook for the detector — you can post anomaly verdicts from your own model.

Anomaly detection on database metrics: why thresholds fail and what works
A walk through forecast bands, change-point detection, multi-variate anomaly, and the seasonality math that makes 'p99 over 200ms' the wrong alert by default — with the Postgres example that broke our last threshold.

Why your Postgres p99 latency lies — and what to track instead
p99 over 1m windows is the most-displayed and most-misleading number on every DBM dashboard. Here's the histogram math, the seasonality math, and a saner default.
