Dati trasmessi in internet in un tema di Superkaramba

[Kaltet]

Ho scaricato da kde-look.org, un tema per superkaramba, non riesco però a visualizzare il grafico dei dati trasmessi e ricevuti in internet. Le righe nel file che si occupano di questo sono:

Dove c'è scritto ppp0 l'ho modificato io, perkè in origine era eth0, ma avendo un modem usb naturalmente il mio protocollo è ppp0. Così mi dice i Total IN e i total OUT, ma non mi fa vedere i dati trasmessi e ricevuti "in tempo reale". Ho notato che in Ksysguard invece me li fa vedere...c'è un modo per accedere a quelle informazioni?
