Save Download traffic size after reset ethernet traffic

[omid1979]

hi all ,
I want to record all my traffic Usage via server's ehternet port
I using command cat /proc/net/dev and cut traffic send/ recive via ethernet like below

cat /proc/net/dev | grep eth1.1 | awk '{print $1,$2,$10}'
eth0 26841759 1221608

Receive: 26841759
Transmit : 1221608

I can save this two parameter to zabbix without problem , but IF I reset the server or disable/enable ehternet port this counter was reset
how can I add new data ( after reset or reboot the server ) to last valid data (befor reset or reboot the server )?
I don't want to reset ethernet Traffic download data
how can I record new data in zabbix Item via formula (for example if newdata<olddata then newdata=olddata+newdata)

Hi

If you have N servers your "tool" is Netflow protocol for traffic accounting and statistics. Or use local counter for accumulated calculated value in cron (script + custom user.parameter in Zabbix agent).

Thanks so much , know I use script +userparameter to do that ,
but If I want to use netflow how can I do ? can I monitor traffic statistics per port for each device using zabbix ?

Netflow consist of 3 main components: collector, sensor, analyzer. You need sensor(for example fprobe on linux hosts, network hardware mostly support out the box) and collector (for example flow-tools) from which you could export statistics to Zabbix. It's a little bit complicated for this topic, but Netflow is more than total traffic statistics.
