Hi, I would like to measure the CPU load for some queuing discipline, and only queuing discipline. Is there any tool witch this can be done.

Perform an experiment like this: Setup a test machine. It runs nothing but traffic management. Push test traffic through the machine. Observe the machine''s CPU load. You can now derive the relationship between traffic level, traffic mix, traffic type and CPU load, by repeating the experiment with different input variables. _______________________________________________ LARTC mailing list / LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/mailman/listinfo/lartc HOWTO: http://lartc.org/

You can did it by wrapping xxx_dequeue routine of the qdisc by calls to TSC counter and accumulate these differences over some time. I measured CBQ and HTB cpu usage by this way as can be seen at HTB home page. devik On Fri, 25 Apr 2003, Srikanth wrote:> >> I would like to measure the CPU load for some queuing discipline, and only > >> queuing discipline.
