The v1.31.0 release of Netdata comes with re-packaged and redesigned elements of the dashboard to help you focus on your metrics, even more Linux kernel insights via eBPF, on-node machine learning to help you find anomalies, and much more.

This release contains 10 new collectors, 54 improvements (7 in the dashboard), 31 documentation updates, and 29 bug fixes.

At a glance

We re-packaged and redesigned portions of the dashboard to improve the overall experience. Part of this effort is better handling of dashboard code during installation—anyone using third-party packages (such as the Netdata Homebrew formula) will start seeing new features and the new designs starting today. The timeframe picker has moved to the top panel, and just to its right are two counters with live CRITICAL and WARNING alarm statuses for your node. Click on either of these two open the alarms modal.

We've also pushed a number of powerful new collectors, including directory cache monitoring via eBPF. By monitoring directory cache, developers and SREs alike can find opportunities to optimize memory usage and reduce disk-intensive operations.

Our new Z-scores and changefinder collectors use machine learning to let you know, at a glance, when key metrics start to behave oddly. We'd love to get feedback on these sophisticated, subjective new brand of collectors!

Netdata Learn, our documentation and educational site, got some refreshed visuals and an improved navigation tree to help you find the right doc quickly. Hit Ctrl/⌘ + k to start a new search!
