Release v1.27.0

The v1.27.0 release of the Netdata Agent brings dramatic improvements to long-term metrics storage via the database engine, and new dashboard features like a time & date picker for visualizing precise timeframes. Two new collectors bring incredible new value to existing features, including a bit of machine learning magic.

This release contains 8 new collectors, 1 new notification method (2 others enhanced), 54 improvements, 41 documentation updates, and 58 bug fixes.

At a glance

The Netdata Agent now uses SQLite to store host, chart, and dimension metadata. This replaces the only metadata log files, which were located inside of the /var/cache/netdata/dbengine folder for both multihost and legacy children nodes streaming to a parent node. With SQLite powering the metadata log, you should notice faster Agent startups, as it no longer needs to replay metadata log files. The Agent no longer puts archived charts into memory on startup, further reducing memory usage. This is just the first of several improvements to the database engine and metadata log, with more coming in future releases.

The database engine now uses a new extent cache that improves query time by 10% under certain workloads and reduces disk I/O by 10%.

The Netdata Agent's local dashboard has received numerous improvements and bugfixes since v1.26. Perhaps most prominent is the new time & date picker, which helps you select precise timeframes when investigating an anomaly or troubleshooting an incident. See the dashboard repository's releases for the full changelog.

We also introduced two new collectors that monitor the Netdata Agent itself in unique ways. First is the anomalies collector, which uses machine learning (ML) to perform unsupervised anomaly detection on a node running the Netdata Agent. This collector trains itself to understand the baseline of specific charts, then charts anomalous data. A new alarms collector visualizes the volume of Netdata alarms triggered over time.
