…pace (eBPF) and user space. This example makes use of PerCpuHashMaps, shows deeper packet inspection via tc context, and loads multiple eBPF programs enabling (ingress and egress) from a single user space application.

Hi @avirtuos! Sorry for late reaction. Usually we add examples to the book with a text chapter talking about it. And the sections of code are being included in the If not, I think maybe it's time to add some |

Hey @vadorovsky , Thanks for the reply. I'd be open to updating the book. I think it might make sense for me to enhance the existing section on classifiers since that make use of the tc-egress example that this PR was inspired by (https://github.com/aya-rs/book/blob/main/docs/book/programs/classifiers.md). What are your thoughts on that approach? I'm also curious if you'd be willing to let me update this chapter as part of a separate PR so that we can get this example out there sooner for prospective users of aya who may be right now struggling to get started with the existing example set. I think its fairly common for folks to check the example directory based on other posts I saw online. Thanks. |
Last week was my first time using aya, and also my first time writing an eBPF program using Rust. My use case was fairly simple - writing a small telemetry agent to gather detailed network byte rate data - but I struggled to find what I needed in the existing documentation and example. I was able to get a few hints in the discord channel and decided to contribute back this stripped down version to the aya documentation.
