[LARTC] Data collection in Linux TC queue
Dear All, Would you guy have any advices concerning how to get some data like queue length, pkt size, and so forth, from the running queue. Right now, I modified the queue disc to print out some info I want using printk() and use syslogd to catch those info up. The problem is, in burst, syslogd can't catch all the msg the queue sent out. Are there any standard or better way to collect those info from the queue disc ? Thank you very much in advance for every advices. -- Sipat Triukose <[EMAIL PROTECTED]> Case Western Reserve University ___ LARTC mailing list / [EMAIL PROTECTED] http://mailman.ds9a.nl/mailman/listinfo/lartc HOWTO: http://lartc.org/
