AI Summary: Promtail's `-inspect` feature fails to observe certain pipeline stages, including `docker`, `cri`, `multiline`, `match`, and `pack`. This occurs because the inspection mechanism only hooks into stages wrapped by `stageProcessor`, leaving unwrapped stages unobserved. The expected behavior is for all pipeline stages, even composite ones like `docker` and `cri`, to be inspectable.
Like Prometheus, but for logs.
