    Hi HN, I'm Tyler Flint, one of the creators of qtap. For a while now, my team and I at Qpoint.io have been grappling with the challenge of understanding what's actually happening inside the encrypted traffic leaving our production systems. Modern apps rely heavily on third-party APIs (think payment processors, data providers, etc.), but once TLS kicks in, figuring out exactly what data is being sent, identifying PII exposure, or debugging integration issues becomes incredibly difficult without resorting to complex and often brittle solutions. Traditional approaches like forward proxies…

    A common open source approach to observability will begin with databases and visualizations for telemetry - Grafana, Prometheus, Jaeger. But observability doesn’t begin and end here: these tools require configuration, dashboard customization, and may not actually pinpoint the data you need to mitigate system risks. Coroot was designed to solve the problem of manual, time-consuming observability analysis: it handles the full observability journey — from collecting telemetry to turning it into actionable insights. We also strongly believe that simple observability should be an innovation…

    eBPF is an amazing technology that allows safely running user-supplied functions at pretty much arbitrary probe points in a kernel/user space context. Much has been written about how amazing this feature is for kernel observability. But as someone who writes user space code, what I find even more amazing is the support for tracing arbitrary user space programs, with no code changes and low overhead. However, doing in-depth analysis can get complicated and time-consuming. My goal with wachy was to make this debugging significantly easier/faster to use, by displaying traces in a TUI…

    Hello Everyone, I'm excited to introduce a new open-source observability platform and would love to hear your feedback. We are aware that there are lots of open-source/commercial tools out there. However, we believe that monitoring the clusters and extracting actionable insights requires deep know-how about the tools/domain. We mainly focused on this problem. - Alaz is an eBPF agent installed on your K8s cluster as DaemonSet. Thanks to eBPF, Alaz collects traces directly from Linux kernels. This means there's no need for sidecars, instrumentations, or service restarts. - The UI not…

    Facebook's Katran looked too scary (and I don't do C++), so I thought I would investigate using XDP/eBPF to redirect packets at high speed and Go to do the control plane work of health-checking backed servers and managing configuration. With luck the resulting binary should be easy to deploy by non-developers. It's still not mature, but seems to work. Code was written in a very exploratory manner, and I'm not a developer so it is quite shocking at the moment, but I aim to improve it. It is intended to be horizontally scalable with ECMP and has been tested on service providing…

    I kept missing incidents until it was too late. By the time my monitoring alerted me, servers/nodes were already unrecoverable. So I built Linnix. It watches your Linux systems at the kernel level using eBPF and tries to catch problems before they cascade into outages. The idea is simple: instead of alerting you after your server runs out of memory, it notices when memory allocation patterns look weird and tells you "hey, this looks bad." It uses a local LLM to spot patterns. Not trying to build AGI here - just pattern matching on process behavior. Turns out LLMs are actually pretty…

    Here's the latest eBPF performance tool of mine - xstack. It's a minimal tool, just 165 lines of eBPF C and under 500 lines of userland C code (including all comments and boilerplate!). It uses the libbpf and (Rust) BlazeSym libraries though (which are a lot of code). The point (and difference) of this tool is that it can sample both the kernel and userspace stack traces of all threads in your system. Traditionally, the "bpf_get_stack()" helper can not read userspace stack traces of other tasks in Linux, but since Linux 5.18 we can combine sleepable eBPF task iterator programs with a new…

    Hi HN! I'm Mo, a platform engineer at Deltaflare working on critical infrastructure protection. I built Cerberus because traditional packet capture tools (tcpdump, Wireshark) have too much overhead for production CNI environments. eBPF lets us filter and classify packets at the kernel level with near-zero performance impact. Some interesting challenges: - eBPF verifier is strict - every memory access needs bounds checking - Limited to 32 bytes of L7 payload (tradeoff between inspection depth and overhead) - TC vs XDP decision (chose TC for compatibility) Looking for contributors, especially…
