I would suggest designing your application using the Observability patter, basically, you will create a path, /metrics for example, and you will hit this path every time you need the application's info. The path is populated of all the information you need (killed threads for example) This approach could be called withe box monitoring: the application knows his status. Then you can either use tools like Prometheus to query the path and create alerts or just hit the path retrieving information which are exposed in the format you want to (json, yml, ecc). The path will be reached using a simple web server, may be integrated into the application as well. Exposing the container port 80 you can basically run a simple curl http://<container name | localhost>/metrics getting all the information you need. You can find a bunch of library you can integrate into your application.
