OpenResty XRay is a dynamic-tracing product that automatically analyzes your running applications to troubleshoot performance problems, behavioral issues, and security vulnerabilities with actionable suggestions.
Under the hood, OpenResty XRay is powered by our Y language, targeting various runtimes like Stap+, eBPF+, GDB, and ODB, depending on the context.
OpenResty XRay is a truly non-intrusive dynamic analysis, which does not require installing any special modules or plugins in the target application, does not require recompiling the target application, and does not even require restarting the running process.
