  title: Puma Control/Status Application Gc Gc Stats API
  version: 1.0.0
  description: 'Puma ships with an optional control/status HTTP application that can be

    bound to a local TCP port or Unix socket and queried for runtime statistics

    and lifecycle control (stop, restart, halt, gc, etc.). Endpoints are

    served by Puma''s built-in status app and require a shared control token

    passed via the `token` query parameter; requests without a valid token

    receive HTTP 403.


    When the status app is started in `data_only: true` mode, only the

    read-only endpoints (`/stats` and `/gc-stats`) are enabled and all other

    paths return 404.
