             Summary: Implement a SiteToSiteMetricsReportingTask
                 Key: NIFI-4809
                 URL: https://issues.apache.org/jira/browse/NIFI-4809
             Project: Apache NiFi
          Issue Type: New Feature
          Components: Extensions
            Reporter: Pierre Villard
            Assignee: Pierre Villard


At the moment there is an AmbariReportingTask to send the NiFi-related metrics of the host to the Ambari Metrics Service. In a multi-cluster configuration, or when working with MiNiFi (Java) agents, it might not be possible for all the NiFi instances (NiFi and/or MiNiFi) to access the AMS REST API.

To solve this problem, a solution would be to implement a SiteToSiteMetricsReportingTask to send the data via S2S to the "main" NiFi instance/cluster that will be able to publish the metrics into AMS (using InvokeHTTP). This way, it is possible to have the metrics of all the instances exposed in one AMS instance.

I propose to send the data formatted as we are doing right now in the Ambari reporting task. If needed, it can be easily converted into another schema using the record processors once received via S2S.
