------------------------------------
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.
