  • v1.26.0 Changes

    October 14, 2020

    🚀 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.

    🐛 Bug fixes

  • v1.25.0 Changes

    September 15, 2020

    🚀 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 Changes

    August 10, 2020

    🚀 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.

We have Kubernetes service discovery, new eBPF metrics like virtual filesystem switch and bandwidth per process out of the Linux kernel at event frequency, more interoperability with your monitoring stack thanks to a new exporting engine, and much more.

    📚 This release contains 2 new collectors, 1 new exporting connector, 1 new alarm notification method, 55 improvements, 45 documentation updates, and 40 bug fixes.

    At a glance

    Our service discovery collector detects Kubernetes (k8s) pods and immediately collects metrics from 22 different services as the associated pods are created, destroyed, and scaled. Service discovery is installed when you use our Helm chart, which means you can now collect and visualize service-, pod-, Kubelet-, kube-proxy-, and node-level k8s metrics with one helm install command and zero configuration. All our Kubernetes monitoring components are open source and free for clusters of any size.

    🐧 Our low-level Linux kernel monitoring via eBPF is now supercharged. Thanks to an integration with apps.plugin, you can now monitor how a specific application interacts with the Linux kernel. This update also includes new metrics, such as virtual filesystem switch, bandwidth per process, and much more. Netdata collects these metrics at an event frequency, even better than our famous 1s granularity, so that you can debug applications or anomalies with pinpoint accuracy. The eBPF collector is also now installed and enabled by default except on static builds.

    Read our guide on troubleshooting apps with eBPF metrics for more details.

    Netdata is now more interoperable with your existing monitoring stack thanks to the exporting engine, which replaces the backends system. You can now export to multiple external databases through Graphite, Google Cloud Pub/Sub, Prometheus remote write, MongoDB, and JSON connectors, plus others. Send metrics as soon as they're collected to enrich single pane of glass views or analyze Netdata's metrics with machine learning.

    Read our guide on exporting metrics to Graphite for specifics on just one of many pipelines you can set up to archive your Netdata metrics.

    📇 We're also releasing an improvement for the availability of your monitoring and metrics: persistent metadata. The Agent now writes metadata to disk alongside metrics to allow access to non-active charts from Netdata Cloud and enable future features.

    📚 We added some enhancements to our documentation site, including a new guides section. We'll continue to populate with more use case- and scenario-based content to help you monitor, troubleshoot, visualize, and export your Netdata metrics.

  • v1.22.1 Changes

    May 12, 2020

    Netdata v1.22.1

    🚑 Release v1.22.1 is a hotfix release to address issues related to packaging and how Agents connect to Netdata Cloud.

    🐳 With packaging, we fixed an error that caused DEB and RPM packages to only display the old dashboard and not the new React version. We also fixed an issue that caused Netdata Docker containers to fail due to incorrect permissions. Finally, we ensured JSON-C is correctly fetched and built for compatibility with Netdata Cloud.

    We appreciate our community's help in identifying and diagnosing these issues so we could fix them quickly.

    ⚡️ For Netdata Cloud, we optimized the on-connect payload sent through the Agent-Cloud link to improve latency between Agents and Cloud. We also removed a check for old alarm status when sending alarms to Cloud via the ACLK.

    ⚡️ Finally, we made a fix that ensures Agents running on systems using the musl C library can receive auto-updates.

    🐛 Bug fixes

    • 🛠 Fixed the latency issue on the ACLK and suppress the diagnostics. (#8992) by amoss and stelfrag
    • ⏪ Restored old semantics of "netdata -W set" command. (#8987) by mfundul
    • ➕ Added JSON-C packaging fils to make dist. (#8986) by Ferroin
    • 🛠 Fixed bundling of React dashboard in DEB and RPM packages. (#8988) by Ferroin
    • ✂ Removed check for old alarm status. (#8978) by stelfrag
    • 🛠 Fixed shutdown via netdatacli with musl C library. (#8931) by mfundul
