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.
