Hello,

With 7.14.0 Elasticsearch has started validating `agent.id` using the `.fleet_final_pipeline-1` [(see the PR)](https://github.com/elastic/kibana/pull/100973), which greatly improves security.

While using Elastic-Agent to fetch information from servers, e.g. web-logs, we would like to make sure that the hostname of the web-server the agent runs on is trusted and has not been tampered with. This would allow us to confidently link events to servers without looking up the `agent.id`. The certificate issued to the Elastic-Agent to converse with Fleet has `cn=<hostname>` as the subject name, so there is a trusted source of this information (the signed certificate).

Is there a way to associate that certificate subject name with the API key given to the Elastic-Agent (in the same way the `agent.id` is) so the `.fleet_final_pipeline-1` can check the `hostname` or certificate subject name as well as just the `agent.id`?

Thanks

I don't think it is something that can be done today. What do you think about opening a Github issue as a feature request for this?
