Should this and some of the other related methods in here be private or at least protected?

I'd be okay with either way. I even though about package protected after I initially wrote it (so it can be tested but not reused). But you're right it doesn't need to be public.

@pickypg Thanks for your feedback. I've simplified the implementation per your recommendation. This is ready for review again. |

Code LGTM. Just some minor doc comments.
| [source,yaml] | ||
| --------------------------------------------------- | ||
| xpack.monitoring.collection.enabled: true | ||
| xpack.monitoring.elasticsearch.collection.enabled: true |
| .. Verify that the `xpack.monitoring.enabled`, | ||
| `xpack.monitoring.collection.enabled`, and | ||
| `xpack.monitoring.elasticsearch.collection.enabled` settings are `true` on each | ||
| node in the cluster. By default, data collection is disabled. For more |

This second sentence is very confusing with this new setting in the mix.
By default
xpack.monitoring.collection.enabledis disabled (false), and that overridesxpack.monitoring.elasticsearch.collection.enabled, which defaults to being enabled (true). Both settings can be set dynamically at runtime.
(Or similar)

| This is different from xpack.monitoring.collection.enabled, which allows you to enable or disable | ||
| all monitoring collection. However, this setting simply disables the collection of Elasticsearch | ||
| data while still allowing other data (e.g., Kibana, Logstash, Beats, or APM Server monitoring data) | ||
| to use through this cluster. |

This is my own bad phrasing:
to use through this cluster.
should probably be
to pass through this cluster.

This one is used in the Rest endpoint to silently block incoming traffic.
