v1.30.0

The v1.30.0 release of Netdata brings major improvements to our packaging and completely replaces Google Analytics/GTM for product telemetry. We're also releasing the first changes in an upcoming overhaul to both our dashboard UI/UX and the suite of preconfigured alarms that comes with every installation.

v1.30.0 contains 3 new collectors, 3 enhancements to notifications method, 38 improvements (13 in the dashboard), 16 documentation updates, and 17 bug fixes.

At a glance

The ACLK-NG is a much faster method of securely connecting a node to Netdata Cloud. In addition, there are no external dependencies to our custom libmosquitto and libwebsockets libraries, which means there's no more need to build these during installation. To enable ACLK-NG on a node that's already running the Netdata Agent, reinstall with the --aclk-ng option:

bash <(curl -Ss https://my-netdata.io/kickstart.sh) --aclk-ng --reinstall

We replaced Google Analytics/GTM, which we used for collecting product telemetry, with a self-hosted instance of the open-source PostHog project. When sending statistics to PostHog, any fields that might contain identifiable information, such as an IP address or URL, are hardcoded. If you previously opted-out of anonymous statistics, this migration does not change your existing settings.

We also published a developer environment (devenv) to simplify contributing to the Netdata Agent. The devenv packages everything you need to develop improvements on the Netdata Agent itself, or its collectors, in a single Docker image. Read more about this devenv, and get started, in the Netdata community repo.

v1.29.2

Release v1.29.2

Release v1.29.2 is a patch release to improve the stability of the Netdata Agent.

We discovered that an improvement introduced in v1.29.0 could inadvertently set all os_* host labels to unknown, which could affect users who leverage these host labels to organize their nodes, deploy health entities, or export metrics to external time-series databases. This bug was fixed in #10647.

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.

v1.28.0

Release v1.28.0 is a hotfix release to address a deadlock in the Netdata Agent. We intended to release this hotfix as v1.27.1, but we can't backtrack on a release once we've begun to publish new Docker images and binary packages on other platforms.

If the Agent-Cloud link (ACLK) connection drops and the Agent fails to queue an on_connect message, it also fails to properly release a lock in the web server thread.

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.

v1.26.0

Release v1.26.0

The v1.26.0 release of the Netdata Agent brings exciting new collectors written in Go, a new integration with the DevOps startup StackPulse, and massive improvements to the way users navigate Netdata's documentation. We've also added compatibility with an exciting new feature that's coming soon to Netdata Cloud—stay tuned!

This release contains 3 new collectors, 1 new notifcation method, 21 improvements, 13 documentation updates, and 12 bug fixes.

At a glance

The Netdata Agent can now collect metrics from files/directories, systemd units, and ISC DHCP servers. These new collectors are part of our larger effort to migrate all collectors to Go, which provides more extensibility compared to previous implementations. You can read about each of these new collectors in our docs: filecheck, systemd, isc_dhcpd.

We're excited to extend our health watchdog even further to integrate with StackPulse, which is designed to help SREs manage and respond to incidents with code and automation. You can read more about how to configure Netdata to send notifications to StackPulse in the docs.

We rearchitected our docs/education site, Netdata Learn, to focus on users actions rather than the Netdata Agent's hierarchy of code. The core docs now better guide users through the most important actions, such as configuring collectors and interacting with charts, independent of whether they use only the Netdata Agent, or the Agent in combination with Netdata Cloud. Of course, all of our reference documentation is still alive and kicking for those who want to dive into every configuration option or API query. We also revamped our guides page with better visuals, a search/filter, and more rational categories.

v1.25.0

Release v1.25.0

The v1.25.0 release of the Netdata Agent is focused on improving Netdata's usability across the board. We added more customization to how the Prometheus collector implemented in v1.24 meaningfully visualizes metrics. In addition, we've focused on fixing bugs and ensuring that core functionality of the Netdata Agent, such as the ACLK, works more efficiently.

This release contains 1 new collector, 27 improvements, 15 documentation updates, and 59 bug fixes.

At a glance

Improved filtering and grouping for the Prometheus collector gives you more flexibility in how Netdata collects and visualizes metrics from more than 600 Prometheus endpoints. The Prometheus collector is designed to visualize every metric exposed on a Prometheus endpoint generically, but one chart for every metric is often not the most meaningful presentation. Filtering and grouping options bring the same "bespoke" feeling that you find in our other collectors, such as having input/output metrics on a single chart instead of two.

You can read about filtering and grouping in our documentation right now. If you haven't heard about the generic Prometheus collector, read our v1.24 blog post for details on why we continuously make Netdata more interoperable with other monitoring solutions.

We also made significant improvements to the robustness and responsiveness of the Agent-Cloud link (ACLK), which is used to stream metrics and alarm status if you sign up for Netdata Cloud and claim your nodes. The disconnect and reconnect process is now more reliable, and all metrics data is now Gzip compressed. Now that the payloads are smaller and more quickly processed, you'll see improved responsiveness when viewing dashboards in Netdata Cloud.

We added a new Elasticsearch collector, written in Go, to help you collect metrics from and monitor Elasticsearch instances. This collector is preinstalled with the Netdata Agent and often works with zero configuration, but can also be tweaked to collect only specific stats, gather metrics with TLS, and more. See the documentation for generated charts and configuration options.

v1.24.0

Release v1.24.0

The v1.24.0 release of the Netdata Agent brings enhancements to the breadth of metrics we collect with a new generic Prometheus/OpenMetrics collector and enhanced storage and querying with a new multi-host database mode.

At a glance

This release broadens our commitment to open standards, interoperability, and extensibility with a new generic Prometheus collector that works seamlessly with any application that makes its metrics available in the Prometheus/OpenMetrics exposition format, including support for Windows 10 via windows_exporter. Netdata will autodetect over 600 Prometheus endpoints and instantly generate charts with all the exposed metrics, meaningfully visualized.

The Netdata Agent database engine enables long-term storage of per-second metrics inside the Agent using both RAM and disk space. In our new, multi-host database mode, parent and child nodes share resources in a single instance. Any pre-existing child node metrics remain in the legacy dbengine paths to ensure backward compatibility. To migrate those nodes to the new multi-host DB, simply delete those metric cache paths. This new mode supports distributed queries for the Agent as well as specific scenarios like streaming metrics from the child to parent database, streaming multiple child nodes to a single parent, and remembering which child or children are connected to the database even if streaming hasn't started.
