-----------------------------------

             Summary: Add all available metrics to PrometheusReportingTask endpoint
                 Key: NIFI-11986
                 URL: https://issues.apache.org/jira/browse/NIFI-11986
             Project: Apache NiFi
          Issue Type: Improvement
          Components: Extensions
            Reporter: Matt Burgess
             Fix For: 1.latest, 2.latest


The Prometheus REST API endpoint includes the following metrics:

* NiFi Metrics Registry
* JVM Metrics Registry
* Connection Analytics Metrics Registry
* Bulletin Metrics Registry
* Cluster Metrics Registry

However PrometheusReportingTask only includes the following:

* NiFi Metrics Registry
* JVM Metrics Registry

This Jira proposes to add the remaining Metrics Registries to PrometheusReportingTask, each with a property (defaulting to false to maintain current behavior) specifying whether to include the metrics in the output. For NiFi 2.0 these properties could default to true instead.
