Mihai Claudiu Capatina <mick@aignet.ro> aka Mick This is a small script that I use on FreeBSD machines running ALTQ This machines acts like a traffic management system and I need to see the traffic for each class ( CBQ ) All you need to change in this script is the path to "altqstat" and the name of the interfaces In my case fxp0 is connected to my LAN and fxp1 is connected to my ISP so...I measure on fxp0 the download and on the fxp1 the upload for each class This script has only one parameter....this is the class number assigned by ALTQ. If you want to use this script I suppose that you already instaled ALTQ In any case do "altqstat -w 0 -c 2 -i your_interface" to see what your class number is...for each class If you want to count packets instead of bytes change the st line of the script instead of $octeti_down and $octeti_up put $pakete_down and $pakete_up You will call this script from mrtg.conf like this : Target[name]: `/your/path/to/my/script/stfc [class_number] - name - can be an ip address or a client name or whatever you want - class_number - explained above... VERY IMPORTANT : always define classes in the same order for upload and download...so they will have the same class number If you need additional information please feel free to mail me...I'll be glad to help you...;-)) Mick <mick@aignet.ro>
