---------------------------------------
Hi [~thierry.prats] - I have been looking into this and I see things properly
populated on my side (using NiFi 2).
Something that is worth mentioning is that the user used to access the endpoint
will need READ access on the root process group. I believe this is the issue
you have here. When a user does not have read permission on a component, it'll
see the UUID instead of the name.

> Key: NIFI-13984
> URL: https://issues.apache.org/jira/browse/NIFI-13984
> Project: Apache NiFi
> Issue Type: Bug
> Components: Core Framework
> Affects Versions: 1.27.0, 1.28.0, 2.0.0
> Reporter: Thierry PRATS
> Priority: Major
>
> The NiFi API endpoints */flow/metrics/json* and */flow/metrics/prometheus*
> return incorrect tags.
> The component_name is equals to component_id. The same issue applies to the
> tags instance, source_name and destination_name, which correspond to their
> IDs instead of their names.
