Incoherent network value between active and passive mode

[spa33fr]

Hello ! I need some help about a problem i can not resolve.

Context:
Client: Zabbix Agent ( Docker latest version ) on a Debian 12 up to date
Server: Zabbix 7.0.9 docker + Debian 12

In active mode, Zabbix server report abnormal traffic on eth0 interface, look:

There is absolutely no traffic and its a 1Gbps link ...

If I switch profil on server to passive mode its ok:


If I check last value in passive mode, it seem to be ok and linear:



If I look the last value in active mode, there is some "noise", i dont understand ?




If I try to zabbix_get from server to agent, i dont have any timeout or incorrect value, same if I query the device on the server with cat /sys/class/net/eth0/statistics/tx_bytes

I dont know how to debug this situation ? Chatgpt tell me about change some buffer value and frequency in my agent, but do you have encounter this problem ?

Thanks a lot for your help
