Hello Everyone!
New video tutorial: Using OpenResty XRay to diagnose high CPU usage in Erlang/OTP applications: https://youtube.com/watch?v=sqB5fGHahYU
Highlights:
• Pinpoint CPU-intensive regex operations, among many other bottlenecks
• Analyze code paths on both the Erlang language level and the VM C/C++ level (with Flame Graphs!)
• Zero-intrusion profiling - no restarts, no special options/flags, and no code changes needed!
• Based on our advanced dynamic tracing tech eBPF+/Stap+/etc.
• Neglectacble tracing overhead; suitable for production use
• Already helping big companies like Zoom, Inc
• Transparently peeking inside already running processes and containers

All the new shiny Erlang dynamic tracing tools are written in our Ylang universal debug language as always: https://blog.openresty.com/en/ylang-intro
