             Summary: Support UpdateAttribute for nifi-minifi-cpp
                 Key: MINIFI-112
                 URL: https://issues.apache.org/jira/browse/MINIFI-112
             Project: Apache NiFi MiNiFi
          Issue Type: Bug
          Components: C++, Core Framework
            Reporter: Randy Gelhausen


nifi-minifi-cpp agents can generate multiple "streams" of flowfiles.

For instance, to monitor a host, nifi-minifi-cpp runs nmon, ps, netstat, and gathers logfiles from applications.

But, for a given flowfile, any downstream NiFi collectors wont have visibility into the originating hostname, nor metadata about which "stream" (ExecuteProcess(nmon), ExecuteProcess(ps), TailFile(app1), TailFile(app2)) generated it.

One solution is to use a separate InputPort for each stream. This works, but burdens both the team working on agent flows, and the team managing the collector- they have to be in concert.

A simpler (better?) approach is to allow agent teams to tag flowfiles with differentiating metadata via use of UpdateAttribute.
