[jira] [Created] (NIFI-6715) Metrics of removed/renamed components continues to remain in PrometheusReportingTask

Kotaro Terada created NIFI-6715:
-----------------------------------

             Summary: Metrics of removed/renamed components continues to remain in PrometheusReportingTask
                 Key: NIFI-6715
                 URL: https://issues.apache.org/jira/browse/NIFI-6715
             Project: Apache NiFi
          Issue Type: Bug
            Reporter: Kotaro Terada
            Assignee: Kotaro Terada


When using PrometheusReportingTask, metrics of removed/renamed components continues to remain after removing/renaming them completely in the NiFi UI. This is supposed to happen because PrometheusReportingTask adds an incremental difference into the Prometheus' collector. To deal with it, we could clear all collectors before returning the metrics.
