From mboxrd@z Thu Jan 1 00:00:00 1970 From: "Ioannis C Avramopoulos (iavramop@Princeton.EDU)" Date: Sun, 23 Jan 2005 05:22:09 +0000 Subject: [LARTC] Determing the pfifo backlog Message-Id: <3d41a0ab2ae2.41f2ee31@Princeton.EDU> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: lartc@vger.kernel.org Greetings -- in the "Linux Advanced Routing & Traffic Control HOWTO" chapter 14.1 on bfifo/pfifo it says that: "you can use this qdisc to determine the backlog on your interface". But it does not say exactly how. Command [#tc -s qdisc ls] outputs the number of packets sent so far but it does not output any info about the backlog. My first question is whether a command exists that provides info about the backlog. My second question is whether a system call exists that provides this info. I would like to be able to query on the backlog at real time and invoking the shell on each such query sounds like a lot of overhead. Kind regards, Yannis _______________________________________________ LARTC mailing list / LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/mailman/listinfo/lartc HOWTO: http://lartc.org/
