A collection of SystemTap-based real-time analysis and diagnostics tools for OpenResty, NGINX, LuaJIT, and ngx_lua. It provides scripts for sampling backtraces, inspecting shared memory and connection pools, detecting leaked memory pools, and monitoring TCP accept queues.

Use cases

• profile nginx cpu usage with flamegraph backtraces
• find memory pool leaks in openresty
• inspect nginx lua shared dict usage
• monitor tcp accept queue overflow on linux
• sample off-cpu time for nginx workers
• trace which files nginx accesses at runtime

When to choose

• you run OpenResty or ngx_lua on Linux and need deep dynamic tracing without code changes
• you need LuaJIT-level backtraces or shared memory inspection in production
• you are on an older Linux stack where SystemTap is the only viable tracing option

When to avoid

• you want a maintained tool - the project is explicitly unmaintained in favor of OpenResty XRay
• you are on non-Linux platforms or cannot install kernel debug symbols and SystemTap
• you only need basic metrics that standard nginx monitoring or eBPF tools provide
