similar to: getting qdisc stats using rtnetlink sockets

I want to implement a snmp-agent to measure the bandwidth traffic per flow in a linux router. Is there any way to use tc in bash scripts in order to measure the bandwidth? In my first thought, the agent would fire repeatedly tc commands that would return the rate /flow. Is that speculation correct? Do you propose an alternative way to measure the bandwith through an agent. I found somewhere

Hi , I''m trying to call the tc_qdisc_modify function of tc in iproute2/tc. I could compile it with my stub program and got the executable. However, when i try to create an htb qdisc i get the following error : Unknown qdisc "htb", hence option "default" is unparsable However, if i use the tc tool, it works fine.. When I tried to understand the problem, it appeared to

As a necessety for my job is to real-time monitor the bytes, packets, packet dropped etc of all the qdiscs working inside the kernel i''ve tried varius methods: 1. Parse tc -s command output and update a round robin database and use rrdtool to graphically display tc statistics. [varius perl scripts exist for the above job] 2. Unsuccesfully tried QoS SNMP extensions, in order to use a

The Linux QoS Library (LQL) provides a GPL licensed, GObject based C API to manipulate the network queueing disciplines, classes and classifiers in the Linux kernel. LQL does not use the TC command as a back-end. Instead, LQL communicates with the Linux kernel via Netlink sockets the same way TC does. 0.5.0 2004-08-30 ----- * Initial public release. * I wanted to get 100% API doc coverage and a

Is there any library that i can hook on at runtime in order to create a qdisc dinamically from a program or if i want to do this I have to call the "tc" command? The disadvantage of calling the tc command from a process is that it creates an other process and this slows things up. Marius

Hi, I''m interested to write rules direct in Kernel space memory and not to execute the tc command. Have anyone done this before ? Any ideas ? Sources ?

I have managed to dynamically parse the output of commands: tc qdisc ls dev eth0 and tc -s class show dev eth0 Save statistics in an rrd database and display it via a php script. see http://143.233.4.215/graph.php and dload scripts from http://143.233.4.210/qos/ My next step in developing this monitoring software is to somehow manage to create a tree out of tc and then use it to greatly

Hi I''m working actually on a project about Qos configuration on a linux computer. I need to access (read/write) at the informations generated by the "tc" command. I think that these informations are in the /proc/net/psched file, but I only got 4 hexadecimal number in it.. Can anyone help me? David

Good morning :) I want to use some c code to read statistics as well as the configured settings ... ..

Hi, A thought for the list. As I mentioned in another posting, there are a lot of QoS mechanisms out there. Linux supports some, but not all. Some patchsets add others, but don''t work for all kernels. There are also userland implementations, usually sitting in software routers, but there are other packages. Would it be helpful if I worked on a table of what''s out there for

Hello everybody, I am new to the lartc mailing list. I have been using "tc" for some time now. To be precise, tc & HTB to shape traffic. I did a lot of search on Google for 2 things: - A GUI to create configure new qdiscs & classes for HTB - A utility that will graph the data sent through all configured classes or qdiscs. I could not find anything. Could someone tell me if a

Hi all, I try to made a C program (CAC (Call Admission Control) module) and I don''t want to use a exec command with TC in my program when I want to add,modify or delete a QoS rule. I search a TC library and I found two projects : LQL (Linux QoS Library) : http://www.coverfire.com/lql/ (c) LTCM : http://hng.av.it.pt/~ltcmmm/ (c++) Do you known these API or others ? If you know them, can

I am a Linux novice. I have set up a Linux Router that is running the 2.6.15-1.2054_FC5 kernel. I boot to an initial router state and then I experiment with various "tc" commands by executing them at the command prompt. I reboot often to restore the initial state. When I booted up the router today I got the following messages during the boot process: Bringing up interface eth0:

what is the script for deleting filter that already exist??? the htb script is: tc qdisc add dev eth0 root handle 1:0 htb default 4 tc class add dev eth0 parent 1:0 classid 1:1 htb rate 500kbps ceil 500kbps tc class add dev eth0 parent 1:1 classid 1:2 htb rate 300kbps ceil 300kbps tc qdisc add dev eth0 parent 1:2 handle 12:0 pfifo tc class add dev eth0 parent 1:1 classid 1:3 htb rate 150kbps

Hi, On this Fedora Core Devel (Raw Hide) system, if I boot on a distribution kernel (based on 2.6.12rc1-bk2) the network is fine. If I build a custom 2.6.12-rc1-V0.7.43-06 or 2.6.12-rc1-mm4 kernel the network interface fails to initialise on boot with RTNETLINK answers: Invalid argument. What can possibly cause this ? My kernel config should be mostly fine - I used it extensively at a time and

how can i get rid of that ?? i do del roots before scripting. -- *Dariusz ''tdi'' Dwornikowski | Gentoo | admin at pozman.pl | *[JID]:tdi@gentoo.pl|[gg]:2266034|[IRC]:#gentoo-pl@freenode | *[MAIL]:tdi@pozman.pl|[WWW]:www.tdi.pozman.pl | *Serwery,administracja,webapps - www.ProAdmin.com.pl | *Fingerprint:43E21CC46DAFD2F754E91547D59B39F56AAA4B5F
