What is xCapture? 0x.tools is a suite of Linux performance & troubleshooting tools built with a preference for minimal dependencies and ease of installation across different Linux systems. It is not a product or a complicated platform that requires months of learning, planning and a SaaS subscription. It’s just a bunch of tools that I’ve first built for myself and the better ones get released, like xcapture today. - Linux, Oracle, SQL performance tuning and troubleshooting training & writing. The previous BCC-based v2 version got a good discussion here last year [1], but due to BCC being less flexible and now deprecated, I decided to pull the plug and start from scratch with the latest eBPF features available.
