## AI overview

Netdata 1.30.0 introduces ACLK-NG, a faster in-house method for streaming metrics between Netdata nodes and Netdata Cloud. The release also adds self-hosted PostHog telemetry, deeper Linux kernel monitoring through eBPF, improved alarms, and Docker and VS Code support for contributors.

## Source excerpt

We're excited to introduce Netdata 1.30.0, which features: ACLK-NG: A new custom library for streaming metrics data on demand, written entirely in-house, that's 4x faster than libmosquitto/libwebsockets. Opt-in product telemetry with PostHog: Goodbye, Google Analytics. Hello, self-hosted instance of PostHog. Deeper Linux kernel monitoring with eBPF: Expanding our reach into the Linux kernel with page cache and synchronization syscall monitoring. Smarter preconfigured alarms: Better (and less noisy) defaults, better information. Developer environment: Contribute to Netdata via a Docker image and VSCode integration. Documentation improvements & tutorials: Better standards for editing files and restarting Netdata, plus brand-new tutorials. ACLK-NG The ACLK-NG is a new, faster method of securely connecting a node running Netdata to Netdata Cloud. In our internal testing, it's 4x faster than our previous implementation, which uses libmosquitto and libwebsockets.

To enable ACLK-NG right now, update your nodes with the -aclk-ng option:
