huge numbers calculation problems?

[mike_k]

I am trying to store speed per second of the incoming and outgoing traffic on one network interface (as integer). Seems, speed for the outgoing one is incorrectly computed by zabbix. It is many times higher the interface's capabilities.

I have a dozen of monitored interfaces on other hosts, but numbers are not so big there... This is the only case where result looks odd.

'ifconfig eth0 | grep bytes':
RX bytes:239478011223 (228384.0 Mb) TX bytes:2180787968981 (2079761.4 Mb)

Actual values from zabbix_get (~10s interval):
input octets: 239370237570, 239372338724,...
output octets: 2176787536722, 2176822785361

(either with net.if.out[eth0] or with cat /proc/net/dev|grep eth0|awk '{print $9}')

output octets (speed per second):
2006.Nov.20 22:11:12 106629273656
