https://github.com/grafana/beyla is cool. The documentation misses some parts, so I havd to dig into GitHub issues, but overall is a great tool.

I spinned up a container next to a microservice and got metrics and traces, which made me happy because I didn't have to do that mundane observability instrumentation stuff. I find it a great tool when you have very little observability and want to quicky go from 0 to 1. However, to go from 1 to 100 you still have to bring some manual instrumentation, unfortunately.

ePBF for Windows, https://github.com/microsoft/ebpf-for-windows.

> eBPF is a well-known technology for providing programmability and agility, especially for extending an OS kernel, for use cases such as DoS protection and observability. This project is a [WIP] that allows existing eBPF toolchains and APIs familiar in the Linux ecosystem to be used on top of Windows. That is, this project takes existing eBPF projects as submodules and adds the layer in between to make them run on top of Windows.

I updated the benchmarks for #epbf overhead in ebpf_exporter.

Overhead for an empty probe for getpid() syscall that immediately returns:

* 15ns for a tracepoint (tp_btf) 🚀
* 24ns for an fentry 🏎️
* 137ns for kprobe 🐌
