Network Receive and Transmit values

[sybex]

Hi, ...

zabbix is not able to get the RX and TX values:

eth0      Link encap:Ethernet  Hardware Adresse 00:1A:4B:B0:30:DE
          inet Adresse:192.168.150.10  Bcast:192.168.150.255  Maske:255.255.255.0
          inet6 Adresse: fe80::21a:4bff:feb0:30de/64 Gültigkeitsbereich:Verbindung

          RX bytes:4573449844425 (4.1 TiB)  TX bytes:26522682680502 (24.1 TiB)
          Interrupt:169 Speicher:f8000000-f8012100 

is there another way to get these? Without restarting the network or recalculating in a strange way?
