Red Hat has a similar eBPF based tool <a href="https:&#x2F;&#x2F;github.com&#x2F;netobserv&#x2F;network-observability-operator">https:&#x2F;&#x2F;github.com&#x2F;netobserv&#x2F;network-observability-operator</a> (Disclaimer: i work on it) - the cool thing imho with retina or redhat netobserv or pixie is they aren&#x27;t tied to a specific CNI. Now one of the problems that arises is potential conflicts and lack of collaboration between eBPF based tools, as there are more and more. Something called bpfman aims to address this aspect

Probably this means it&#x27;s not for me, but what is this useful for?<p>Anyone using this in their prod set-up and has a scenario where they found this useful?

There is a flood of observability tools based on eBPF coming out these days [1]. eBPF is used to collect metrics without the need to instrument the code.<p>--<p>1: <a href="https:&#x2F;&#x2F;ebpf.io&#x2F;applications&#x2F;" rel="nofollow">https:&#x2F;&#x2F;ebpf.io&#x2F;applications&#x2F;</a>

Speaking of observability tools. Anybody here know how to gather more in-depth metrics on mTLS requests? Have an internal (self signed) CA and just want to know which issued certs are presented to nodes. Would be nice to get cert serial number and other metadata as well

What&#x27;s the performance impact of using VM-based eBPF for these tasks instead of native code?

Sigh, anyone have a name suggestion for a (Rust) RTSP library? <a href="https:&#x2F;&#x2F;crates.io&#x2F;crates&#x2F;retina" rel="nofollow">https:&#x2F;&#x2F;crates.io&#x2F;crates&#x2F;retina</a>
