This information comes from the network interface statistics that are on kernel level. They are reset when you reboot your machine or reload a network interface. Zabbix has no control over that. What you could do is have some kind of cron job that would reset network interface statistics every month.

yes but when data sends to zabbix it can manage history and set period output to them, filler 1month 3month and so on
