You can use this python script (from Alexander Chernikov): https://github.com/ocochard/BSDRP/blob/master/BSDRP/Files/usr/local/bin/nic-queue-usage Here is an example showing traffic shared between all 8 queues: [root@hp]~# nic-queue-usage cxl0 [Q0 346K/s] [Q1 343K/s] [Q2 339K/s] [Q3 338K/s] [Q4 338K/s] [Q5 338K/s] [Q6 343K/s] [Q7 346K/s] [QT 2734K/s 3269K/s -> 0K/s] [Q0 347K/s] [Q1 344K/s] [Q2 339K/s] [Q3 339K/s] [Q4 338K/s] [Q5 338K/s] [Q6 343K/s] [Q7 346K/s] [QT 2735K/s 3277K/s -> 0K/s] [Q0 344K/s] [Q1 341K/s] [Q2 338K/s] [Q3 338K/s] [Q4 337K/s] [Q5 337K/s] [Q6 342K/s] [Q7 345K/s] [QT 2727K/s 3262K/s -> 0K/s] [Q0 355K/s] [Q1 352K/s] [Q2 348K/s] [Q3 349K/s] [Q4 348K/s] [Q5 347K/s] [Q6 352K/s] [Q7 355K/s] [QT 2809K/s 3381K/s -> 0K/s] [Q0 351K/s] [Q1 348K/s] [Q2 344K/s] [Q3 343K/s] [Q4 342K/s] [Q5 344K/s] [Q6 349K/s] [Q7 352K/s] [QT 2776K/s 3288K/s -> 0K/s] [Q0 344K/s] [Q1 341K/s] [Q2 338K/s] [Q3 339K/s] [Q4 338K/s] [Q5 338K/s] [Q6 343K/s] [Q7 346K/s] [QT 2731K/s 3261K/s -> 0K/s] Thanks _______________________________________________ freebsd-net@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-net To unsubscribe, send any mail to "freebsd-net-unsubscr...@freebsd.org"
