There's an arms race to add eBPF (BPF) to commercial observability products, and in this post I'll describe how to quickly do that. People like to show me their BPF observability products after they have prototyped or built them, but I often wish I had given them advice before they started. You might not even like BPF.

It is being developed for BSD, too, where BPF originated. That post covered the [bcc] front end (BPF Complier Collection), which has let me rewrite my DTraceToolkit tools. Internally, bpftrace uses a lex/yacc parser to convert programs to AST, then llvm IR actions, then BPF. It's shaping up to be a DTrace version 2.0:
