Show HN: Xcapture-BPF – like Linux top, but with Xray vision
0x.tools simplifies Linux application performance analysis without requiring upgrades or heavy frameworks. It offers thread monitoring, CPU usage tracking, system call analysis, and kernel wait location identification. The xcapture-bpf tool enhances performance data visualization through eBPF. Installation guides are available for RHEL 8.1 and Ubuntu 24.04.

0x.tools is an open-source utility designed for analyzing application performance on Linux systems. It aims to simplify deployment and minimize dependencies for systematic troubleshooting. The tools provided do not require OS upgrades, kernel modules, heavy monitoring frameworks, Java agents, or databases. They can even function on older Linux kernels, like version 2.6.18. Users can measure individual thread activity, CPU usage, system calls, and kernel wait locations. xcapture-bpf, a tool within 0x.tools, offers extended capabilities like viewing performance data from various angles using eBPF instrumentation. While still in beta, xcapture-bpf is not recommended for busy production systems. Installation instructions are provided for RHEL 8.1 or Ubuntu 24.04. The toolset includes real-time interactive utilities and low-overhead thread activity samplers for continuous profiling of production systems. These tools offer insights into system behavior and allow for detailed performance analysis.

6 commentseBPF is really a superpower, it lets you do things which are incomprehensible if you don’t know about it.
With Intel CET's tech there should be way to capture a shadow stack, that really just contains entry points, but wondering if that's going to be used...
