Date: Tue, 1 Jul 2008 16:50:03 +0300 From: "Ian Brown" <ianbrn@...il.com> To: "Andi Kleen" <andi@...stfloor.org> Cc: netdev@...r.kernel.org Subject: Re: [RFC] UDP SndbufErrors interface and the /proc/net/udp interface. Hello, >That might be overriden by a very clear use case. What I had in mind is this: This can help in debugging problems. I have a machine which works with many UDP sockets. After some hours (sometimes days), there are problems ; some of them might be due to that UDP packets are not sent. I want to know stats per UDP port so that I will know for each socket how many packets were not sent; in current implementation, I can only know the total of these packets, and not per port (by probing into the /proc/net/snmp stats) Regards, Ian On Tue, Jul 1, 2008 at 1:18 PM, Andi Kleen <andi@...stfloor.org> wrote: > "Ian Brown" <ianbrn@...il.com> writes: >> >> I wonder: would such a patch (form me or others) in needed ?
