Anomaly Rates in the Menu!
The menu (on the overview or single node tab) now has an anomaly rate button built into it that, for the entire visible window or a highlighted time range, shows the maximum chart anomaly rate within each section.
Read on to learn more about this new feature!
Anomaly detection on Prometheus metrics
We have recently extended the native machine learning (ML) based anomaly detection capabilities of Netdata to support all metrics, regardless on their collection frequency (
Previously only metrics collected every second were supported, but now Netdata can run anomaly detection out of the box with zero config on metrics with any collection frequency.
This post will illustrate an example of what this means using Prometheus metrics (via the Netdata Prometheus collector) since they typically have a default collection frequency of 10 seconds.
Extending Netdata's anomaly detection training window
We have been busy at work under the hood of the Netdata agent to introduce new capabilities that let you extend the "training window" used by Netdata's native anomaly detection capabilities.
This blog post will discuss one of these improvements to help you reduce "false positives" by essentially extending the training window by using the new (beautifully named)
number of models per dimension configuration parameter.
How Netdata’s Machine Learning works
Following on from the recent launch of our Anomaly Advisor feature, and in keeping with our approach to machine learning, here is a detailed Python notebook outlining exactly how the machine learning powering the Anomaly Advisor actually works under the hood.

Introducing Anomaly Advisor – Unsupervised Anomaly Detection in Netdata
Today we are excited to launch one of our flagship ML assisted troubleshooting features in Netdata – the Anomaly Advisor.
The Anomaly Advisor builds on earlier work to introduce unsupervised anomaly detection capabilities into the Netdata Agent from v1.32.0 onwards.
