Release v1.29.0

The v1.29.0 release of the Netdata Agent is a maintenance release that brings incremental but necessary improvements that make your monitoring experience more robust. We've pushed improvements and bug fixes to the installation and update scripts, enriched our library of collectors, and focused on fixing bugs reported by the community.

This release contains 2 new collectors, the migration of 3 collectors from Python to Go, 25 other improvements, 25 documentation updates, and 26 bug fixes.

At a glance

Netdata now collects and meaningfully organizes metrics from both the Couchbase JSON document database and the nginx-module-vts module for exposing metrics about NGINX virtual hosts. Click either of the links to head straight into the documentation that explains what they collect and how to configure both based on whether they're collecting over localhost or across nodes.

We've also migrated more collectors from Python to Go in our continued efforts to make data collection faster and more robust. The newest effort includes our Redis, Pika, and Energi Core Wallet collectors.

On the dashboard, we improved the responsiveness of panning forward and backward through historical metrics data by preventing unnecessary updates and reducing the number of calls. The charts should also now immediately update when you stop panning.
