How to Add eBPF Observability to Your Project
When it comes to integrating security, networking, and observability features, working within the Linux kernel is perfect. It is not, however, without its difficulties. Historically, developers have encountered complex architectures and difficult-to-debug abstraction layers, altered kernel source code or added modules. Both of these issues are addressed by the extended BPF (eBPF).
The Extended Berkeley Packet Filter (eBPF) is a kernel feature introduced in Linux 4.x that enables programs to run without modifying the kernel source code or installing extra modules. Consider it a lightweight, sandbox virtual machine (VM) embedded within the Linux kernel, where programmers can execute BPF
