Release v1.22.0

Release v1.22.0 marks the official launch of our rearchitected Netdata Cloud! This Agent release contains both backend and interface changes necessary to connect your distributed nodes to this dramatically improved experience.

Netdata Cloud builds on top of our open source monitoring Agent to give you real-time visibility for your entire infrastructure. Once you’ve connected your Agents to Cloud, you can view key metrics, insightful charts, and active alarms from all your nodes in a single web interface. When an anomaly strikes, seamlessly navigate to any node to troubleshoot and discover the root cause with the familiar Netdata dashboard.

Sign in to Cloud and read our Get started with Cloud guide for details on updating your nodes, claiming them, and navigating the new Cloud.

While Netdata Cloud offers a centralized method of monitoring your Agents, your metrics data is not stored or centralized in any way. Metrics data remains with your nodes and is only streamed to your browser through Cloud.

In addition, Cloud only expands on the functionality of the wildly popular free and open source Agent. We will never make any of our open source Agent features Cloud-exclusive, and we will actively continue to develop the Agent so that we can integrate new features with Netdata Cloud.

This release also contains 1 new collector, 1 new exporting connector, 1 new alarm notification method, 27 improvements, 16 documentation updates, and 22 bug fixes.

At a glance

We added a new collector called whoisquery that helps you monitor a domain name’s expiration date. You can track as many domains as you’d like, and set custom warning and critical thresholds for each. For more information on setup and configuration, see the Whois domain expiry monitoring documentation.

We added a new connector to our experimental exporting engine: Prometheus remote write. You can use this connector to send Netdata metrics to your choice of more than 20 external storage providers for long-term archiving and further analysis.

Our new documentation experience is now available at Netdata Learn! We encourage you to try it out and give us feedback or ask questions in our GitHub issues. Learn features documentation for both the Agent and Cloud in separate-but-connected vaults, which streamlines the experience of learning about both products.

While Learn only features documentation for now, we plan on releasing more types of educational content serving the Agent’s open-source community of developers, sysadmins, and DevOps folks. We’ll have more to announce soon, but in the meantime, we hope you enjoy what we believe is a smoother (and prettier) docs experience.

Breaking changes

• The previous iteration of Netdata Cloud, accessible through various Sign in and Nodes view (beta) buttons on the Agent dashboard, is deprecated in favor of the new Cloud experience.
