Hey Radioteacher, we (QoE) team really appreciate your feedback. We were able to reproduce similar behavior and believe it's caused by keep-alive packets in CIFS protocol. Based on this info, we are working on potential solution that should help to improve accuracy in such situations.
Once more, thanks a lot for reporting this back to us and help to improve QoE!
I am always happy to help out. My thought is that the more feedback I can provide.....the better products Solarwinds build.....the better I can monitor my equipment.
I am currently in three SW beta programs.
