This behavior is consistent across all keys; each key self-documents itself with valid examples.

## Dynamic systems without restarting server

The following sub-systems are dynamic i.e., configuration parameters for each sub-systems can be changed while the server is running without any restarts.

```
api                   manage global HTTP API call specific features, such as throttling, authentication types, etc.

istioctl manifest generate > 1.yaml
istioctl manifest generate -f samples/pilot-k8s.yaml > 2.yaml
istioctl manifest diff 1.yam1 2.yaml
```

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
```
