In the cloud-native era, Envoy has become a critical building block for modern service meshes and API gateways. Its powerful Lua scripting brings incredible flexibility—but also introduces hidden performance pitfalls. When latency spikes, where’s the problem really coming from? Is Envoy itself too resource-intensive? Is our Lua script creating a bottleneck? Is it CPU-bound computation—or I/O that’s stalling the entire chain? In the past, getting these answers in real time was nearly impossible. Today, OpenResty XRay brings end-to-end observability and takes you straight to the root cause—with zero guesswork. ✅ Real-time Flame Graphs: Instantly capture on-CPU and off-CPU flame graphs from live Envoy instances—no restarts, no downtime. ✅ Automatic Root-Cause Analysis: AI-powered diagnostics predict and prevent issues before they impact users, enabling proactive performance tuning. With OpenResty XRay, you move from reactive firefighting to predictive, automated performance management.

Tired of battling Java memory issues? Frustrated by traditional diagnostic tools that are complex, disruptive, and often demand costly restarts, parameter tweaks, or even JDK replacements? It doesn’t have to be this hard anymore. Introducing the all-new OpenResty XRay Java Memory Analysis Tool — designed to make memory diagnostics simple, fast, and production-safe. ✨ Attach Anytime, No Hassle: Forget about code changes or JDK swaps. Instantly hook into any running Java process — whether it’s OpenJDK, OracleJDK, or beyond — with zero downtime. 🧠 Visualize What Really Matters: Our exclusive Memory Reference Path Graph lets you see the actual memory flow and object relationships at a glance — no more guesswork. 🛡️ Built for Production: With minimal overhead, XRay is safe to use on your live, mission-critical systems without impacting performance. And it doesn't stop at Java — XRay also supports live memory analysis for Lua, Python, PHP, and Perl. Finally, you can answer: Where did all my Java memory go?

Our OpenResty XRay, a dynamic-tracing product, transforms black-box production systems into white-box ones. Many issues can be observed and captured before they escalate into harmful problems. This continuous insight and control over production systems is what's most crucial. Offline simulated traffic and testing methods often have limited coverage. No matter how much effort is invested in offline simulation, gaps will always exist. Additionally, many of our customers prefer using OpenResty XRay for white-box analysis even in offline environments; regardless of the environment, white-box is much more convenient than black-box. You can't keep adding monitoring metrics and debug logs every time, can you? 😉 Our ultimate goal is to help customers quickly understand their legacy systems (or "sh*t mountain systems") and improve them efficiently at low cost rather than just being a tool for solving production issues. "Turning sh*t into gold" - that's what makes this truly interesting and valuable. 😎 Request your OpenResty XRay trial here: https://lnkd.in/g444Rh6E

Many users ask us about the implementation principles and technology behind OpenResty XRay, as it looks magical! 🤩 • For those interested, you can refer to our previous article about dynamic tracing: https://lnkd.in/gvkR8uK8 • Here's another series of articles our CEO wrote introducing the ylang language: https://lnkd.in/gnsmzBUS • And here's an article about the y++ language: https://lnkd.in/eemv8e8F Our recent advanced dynamic tracing capabilities for Java are implemented using our C++-compatible y++ language. Interestingly, our team has been using OpenResty XRay to analyze OpenResty XRay itself. However, this capability is disabled for our customers to prevent misuse.

OpenResty XRay now supports setting dynamic probes at any #Java function entry point! This feature has wide applications - for example, we've implemented real-time latency statistics for requests within Tomcat servers based on this feature, and integrated it with our online intelligent packet capture analyzer. It doesn't depend on any configuration of the target process or log files. It supports both interpreted and JIT-compiled Java methods. It's still based on 100% non-intrusive dynamic tracing technology, with negligible performance overhead. It doesn't rely on bytecode injection or machine code injection, doesn't depend on JVM Agent mechanism, and is completely read-only for the JVM target process - the target process doesn't even need to restart. It supports both the latest Linux kernels and old Red Hat 7's 3.10 kernel. Since this feature is very new, it currently only supports OpenJDK, but will soon support Oracle JDK. In the near future, it will definitely support more variants like Zulu JDK, IBM JDK, Azul JDK, and others. Support for dynamic probes at Java function exit points will be added later.

Following OpenJDK, our OpenResty XRay can now deeply analyze #OracleJDK! We're still using our 100% non-intrusive dynamic tracing technology. The analysis covers everything from the C++ VM level to the #Java source code level without any blind spots. Next up will be other JDK variants like Zulu JDK and IBM JDK 😃 #JVM #java #DynamicTracing #eBPF
