Analyzer ngx-graceful-exits

# Name

ngx-graceful-exits - Nginx Graceful Exit Event

This analyzer monitors graceful exit events in Nginx-based applications including OpenResty, OpenResty Edge, Kong, and APISIX. It captures stack traces when the Nginx worker processes receive shutdown signals and begin their graceful termination sequence. The analyzer helps diagnose issues related to worker process lifecycle management, connection draining, and proper cleanup during server restarts or reloads.
