The description here should mention that it is only used when the reporting
task is configured to use a Record Writer. For the one you added, it has two
modes, but future reporting tasks need not offer an alternative.
> 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
> Priority: Major
>
> 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.
