Analyzer openresty-cosocket-connect

# Name

openresty-cosocket-connect - OpenResty Cosocket Connect Operation Flame Graph

This analyzer profiles cosocket connection establishment operations in OpenResty-based applications including Kong and APISIX. It captures Lua-land stack traces during cosocket connect calls, generating flame graphs that visualize the execution paths when establishing upstream connections. The analyzer helps identify performance bottlenecks in connection establishment, troubleshoot connection failures, and optimize connection pooling strategies.
