pre zobrazovanie traffic v realnom case je dobry aj ifstat vyzera asi takto:

$ ifstat -b -i br0,br1,tap9
       br0                 br1                 tap9
 Kbps in  Kbps out   Kbps in  Kbps out   Kbps in  Kbps out
  142.85     33.07      0.00      0.00    180.72     35.32
  407.03     43.88      0.00      0.00    469.40     13.92
   38.42      9.33      0.00      0.00     33.98     18.95
  581.49     66.32      0.00      0.00    538.21     45.90
 2931.95    289.26      0.00      0.00   2613.19    105.40
 1539.07    140.58      0.00      0.00   1382.33     50.46
    0.81      1.32      0.00      0.00      0.00      0.00

Kazdu sekundu novy riadok. Co je na mon ine/zaujimave, ze vie ukazovat traffic
aj v Kbps (-b).

Pre fanusikov ascii je pekny bmon:

vie robit minutove a hodinove priemery a ukladat aj do html. Co sa da rsync-ovat
na nejaky centralny stroj.

No a na "profesionalne" monitorovanie traffic existuju mrtg alebo cacti
(vyzaduju snmp server na kazdej monitorovanej masine) alebo munin ktory kresli
grafy asi zo vsetkeho co je na masinach (ma vlastneho deamona).

Nieco este chyba do zbierky? :-)

Aj ked neviem ci Marcelovi zrovna slo o statistiky na interfaces...

Pekny den,
Jozef.
