marco polo updated MINIFICPP-31: -------------------------------- Fix Version/s: 0.5.0 > Support UpdateAttribute for nifi-minifi-cpp > ------------------------------------------- > > Key: MINIFICPP-31 > URL: https://issues.apache.org/jira/browse/MINIFICPP-31 > Project: NiFi MiNiFi C++ > Issue Type: New Feature > Reporter: Randy Gelhausen > Assignee: Andrew Christianson > Priority: Major > Fix For: 0.5.0 > > > 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. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
