Analyzer lj-lua-full-bt

# Name

lj-lua-full-bt - Dump Lua Full Backtrace including the variables in the stack

This analyzer captures complete Lua-level stack traces in LuaJIT-based applications such as OpenResty, Kong, and APISIX. It provides detailed backtraces including function call chains and local variable values at each stack frame. The analyzer is invaluable for debugging complex Lua code execution paths, understanding runtime state, and diagnosing application logic errors in production environments.
