    Netflow and WSUS

    searnhardt

      This morning, we experienced a company wide (7 site) slowdown.  In trying to read / interpret the Solarwinds products, the thing that jumped out at us was that our gateway router was running pretty much 100% outbound.  However, when we looked at our NTA graphs, nothing jumped out at us as being the definitive culprit.

      While in "fire-fighter" mode, we decided to turn off our MS WSUS website.  As soon as we did that, traffic immediately went back to normal.

      So, the question is, what did we miss?  Why wasn't it obvious via a top talker or top endpoint graph?

      Related question:  In the setup of the monitored ports and applications.  If we do NOT choose a port to be monitored, is that traffic discarded or added to an "other" bucket?  So, let's say we are NOT monitoring HTTP traffic and we go to a website that 100% utilizes the bandwidth on the router.  Will NTA not show "anything" or will it show that the router is 100% utilized by unknown traffic?

          Hi searnhardt,

          if you choose a port not to be monitored, that traffic would go to 'Unmonitored traffic'. You can drill down to that traffic to see which ports compose that category. This applies to Top Applications resource only, other resources display traffic regardless of port.


          Regards,

              That helps, I'll have to wait until the next emergency (or try to simulate one) to verify.  Just an odd question I guess, rather than trying to find what application is using the TOP bandwidth, I'm looking for something that will tell me EVERY device on the network is streaming from the same source.  You'd think it would be the top endpoint.  However, the WSUS server wasn't showing up there either.  Things that make you go hmmmm....
