eBPF: Network Metrics - Now GA!

The Extended Berkeley Packet Filter (eBPF) is a transformative technology introduced in Linux 4.x that allows bytecode to run within the Linux kernel, providing secure and efficient access to kernel resources. New Relic has harnessed this technology to launch a new eBPF-based agent that simplifies observability by consolidating network performance, application performance management (APM) telemetry, infrastructure metrics, and logging data into a single stream. This agent, designed to function with minimal overhead, eliminates the need for multiple data collection methods and improves visibility across dynamic environments. By offering insights directly from the kernel, eBPF Network Metrics enhance the ability to diagnose network-related issues, such as TCP handshake latency and DNS failures, without requiring changes to application code. This approach significantly reduces the time required to identify network performance issues, thereby lowering operational costs and improving mean time to resolution. The solution provides a comprehensive view of network behavior, correlates it with application and infrastructure performance, and integrates seamlessly into existing workflows, offering a single-agent, language-agnostic method of collecting kernel-level telemetry.
