The profile dump sub-command supports a couple of useful flags:

- `config-path`: select the root for the configuration subtree you want to see e.g. just show Pilot:

```bash
istioctl profile dump --config-path components.pilot
```

This has two implementations:
* The Credentials controller is responsible for reading TLS certificates, stored as Secrets.
* The Kubernetes Service Discovery controller is a bit of a monolith, and spins off a bunch of other sub-controllers in addition to the core service discovery controller.

Because of the monolithic complexity it helps to see this magnified a bit:
