## What is eBPF?
eBPF (Extended Berkeley Packet Filter) is a revolutionary technology that allows developers to write small programs that run in the Linux kernel. Originally designed for packet filtering, eBPF has evolved into a versatile tool for tracing, monitoring, and profiling system behavior. With eBPF, you can instrument almost any part of the Linux kernel or user-space programs to collect performance data, enforce security policies, or even debug systems in real time—all without the need to modify the kernel source code or restart the system.
