It looks the code below doesn't evaluate expression language when getting
the value, so we should either set this to false, or evaluate below.
> Implement SiteToSiteStatusReportingTask
> ---------------------------------------
>
> Key: NIFI-3674
> URL: https://issues.apache.org/jira/browse/NIFI-3674
> Project: Apache NiFi
> Issue Type: Improvement
> Components: Core Framework
> Affects Versions: 1.1.1
> Reporter: Joseph Gresock
> Assignee: Joseph Gresock
> Priority: Minor
> Labels: Site-to-Site, reporting_task, status
>
> I would like to see a reporting task similar to
> SiteToSiteProvenanceReportingTask that sends controller status events using
> JSON over S2S. Since the ProcessGroupStatus object structure is recursive,
> ideally the JSON structure would be flat, with references to parentIds
> embedded.
> This would allow status history to be stored using any arbitrary mechanism.
> Other interesting features would include:
> * Properties to filter which components to include (Process Group, Processor,
> Input/Output Ports, Remote Process Group, Connection)
> * Properties to filter by regex which component names or ids to include in
> the output
