Hi, I installed vnstat, which is a bandwidth monitoring app. I noticed that for some reason its TX bytes were 0, but the RX bytes were being tracked as expected. I don't know how vnstat is collecting its metrics every 5 minutes, but I'm guessing it's similar to how 'netstat -I xn0 -bn' would collect its details. After running 'netstat -I xn0 -bn', I notice that "Obytes" for "<Link#2>" is 0, which may be the problem. However, the "Obytes" for the actual IP address seems to be working: # netstat -I xn0 -bn Name Mtu Network Address Ipkts Ierrs Idrop Ibytes Opkts Oerrs Obytes Coll xn0 1500 <Link#2> <REDACTED> 22659117 0 0 2579194762 21221967 0 0 0 xn0 - 10.0.10.0/24 10.0.10.40 22567359 - - 2258113267 21130240 - 3518207522 - On a different machine that command works fine. It is running BSD 11 as well, but it's not using the xn driver -- it uses the fxp driver. It's output is: # netstat -I xn0 -bn Name Mtu Network Address Ipkts Ierrs Idrop Ibytes Opkts Oerrs Obytes Coll em0 1500 <Link#1> <REDACTED> 1507204306 0 0 1567750969110 100389817 0 80619546746 0 em0 - 192.168.10.0/ 192.168.10.10 1506281038 - - 1548639235291 100283723 - 79211140098 - I'm running FreeBSD 11 on both instances, except the one that's having difficulty is running on AWS, so is on Xen. Any insight into how to fix this so "Obytes" populates for "Link#2"? Thanks!
