Well, i can give you pointers and if you are really serious you will invest the time. - use iproute2 and see how one dumps netdevice stats - Continue by looking at iproute2/ip/ files iplink.c and ipaddress.c and note that: stats are stored in a TLV IFLA_STATS and are printed in print_linkinfo() The code is not much to study if you are serious about performance. Thomas Graf as well has been trying to make it simpler to do this kind stuff. I havent looked at it lately but should make it simpler. If you can beat the performance of that with your half-assed tool then i will be interested in showing up. For now you are on your own on or maybe someone else has time. cheers, jamal - To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
