+ <p>
+ The Site-to-Site Metrics Reporting Task allows the user to publish NiFi's metrics (as in the Ambari reporting task) to the
+ same NiFi instance or another NiFi instance. This provides a great deal of power because it allows the user to make use of
+ all of the different Processors that are available in NiFi in order to process or distribute that data.
+ </p>
+
+ <h2>Ambari format</h2>
+
+ <p>
+ There are two available output formats. The first one is the Ambari format as defined in the Ambari Metrics Collector
+ API which is a JSON with dynamic keys. If using this format you might be interested by the below Jolt specification to
+ transform the data.
+ </p>
+
+ <pre>
+ <code>
+ [
+ {
+ "operation": "shift",
+ "spec": {
+ "metrics": {
+ "*": {
+ "metrics": {
+ "*": {
+ "$": "metrics.[#4].metrics.time",
+ "@": "metrics.[#4].metrics.value"
+ }
+ },
+ "*": "metrics.[&1].&"
+ }
+ }
+ }
+ }
+ ]
+ </code>
+ </pre>
+
+ <p>
+ This would transform the below sample:

+ <p>
+ The Site-to-Site Provenance Reporting Task allows the user to publish all of the Provenance Events from a NiFi instance back to
+ the same NiFi instance or another NiFi instance. This provides a great deal of power because it allows the user to make use of
+ all of the different Processors that are available in NiFi in order to process or distribute that data. When possible, it is
+ advisable to send the Provenance data to a different NiFi instance than the one that this Reporting Task is running on, because
+ when the data is received over Site-to-Site and processed, that in and of itself will generate Provenance events. As a result, there
+ is a cycle that is created. However, the data is sent in batches (1,000 by default). This means that for each batch of Provenance events
+ that are sent back to NiFi, the receiving NiFi will have to generate only a single event per component.
+ </p>
+
+ <p>
+ By default, when published to a NiFi instance, the Provenance data is sent as a JSON array. However, the user can define a Record Writer
+ and directly specify the output format and data with the assumption that the input schema is defined as follows:
