Zabbix Resets Bandwidth at 4.28G

[nsjcn]

I have a key that checks the outgoing bandwidth on a server.
Everything is working but the bandwidth counter resets at 4.28G.
I'm not sure whats going on or why this is happening. Can someone
shed some light on this issue.

can you please check the exact bytes? maybe its a limiteation of 32Bit counter

Since it updates only every 30 seconds it resets at different integers. It is because of the 32 bit integer limit but I don't know how to overcome it. Is there something I can change that will keep adding it up?

Usually using 32bit counters is not an issue as mainly on monitoring network interfaces people are monitoring current speed of data transfer than volume of transferred data (metric from attached picture should be not "as is" but "delta per second")
