Hello, I am using 6.x logstash with default netflow plugin. I am trying to read netflow v9 records from Riverbed Steelhead. V5 works, but when i switch to v9...nothing is displayed (if i run interactively with -f). In the log, i am seeing the following errors: [2017-12-20T17:04:19,710][WARN][logstash.codecs.netflow] Can't (yet) decode flowset id 300 from source id 3203342338, because no template to decode it with has been received.
