Analyzer lua-gco-ref

# Name

lua-gco-ref - GC Object Reference Flame Graph for Stand Lua

This analyzer profiles garbage collection object references in standard Lua applications and Redis with Lua scripting. It captures the reference chains and allocation sites of GC-managed objects in memory. The analyzer generates flame graphs that visualize object reference relationships and memory consumption patterns, helping identify memory leaks, excessive object retention, and memory optimization opportunities in Lua applications.
