I am creating some custom nagios plugins and I am scraping data from xen using the nagios command: /usr/sbin/xentop -b -i 2 -d1 I am trying to get the network tx / rx data, however I think I am missing something here. NETTX(k) NETRX(k) So total network bandwidth is 1048576 k if the above header from xentop is true. So I am wondering why the output for each vm exceeds the theoretical max, Is it really not measured in kilobits, or maybe there is something screwy with the counters? Any help is much appreciated. If I add up all my vm values for RX I get: 5527563 k This is greater than my gigabit connection which is: 1048576 k Thank you! _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

This would come up in your vm traffic but not go out the gig link.

I could be wrong, but I think you are reading the data wrong.
I believe NETTX(k) and NETRX(k) are counters for the dom0 and domUs that
show the total amount of data that has passed through their respective vif
interfaces since they were started. To verify, you could start a new domU,
or restart an existing one. If I am correct, you can run the command you
used to get the output below, and your numbers should all be the same or
higher.
