[jira] [Created] (NIFI-8272) Deleted/renamed metrics are still being shown in the REST API Prometheus endpoint

Noble Numbat created NIFI-8272:
----------------------------------

             Summary: Deleted/renamed metrics are still being shown in the REST API Prometheus endpoint
                 Key: NIFI-8272
                 URL: https://issues.apache.org/jira/browse/NIFI-8272
             Project: Apache NiFi
          Issue Type: Bug
    Affects Versions: 1.12.1, 1.13.0, 1.14.0
            Reporter: Noble Numbat


Processors, connections, funnels, etc that have been deleted/renamed from a flow are still being shown in the REST API Prometheus metrics endpoint at their last reported value before they were deleted/renamed.

I checked the PrometheusReportingTask and deleted items are not displayed in the metrics output as I would expect is the correct behaviour.

The bug can be replicated with a flow as simple as a single processor by deleting the processor and observing the metrics still included on subsequent calls to the endpoint.
