SNMP DAta usage returning values every 30 seconds

Hi all!

i am just trying to monitor the data usage of the following device:

Model Pepwave MAX HD2
Product Code MAX-HD2-M-LTEA-W-IP67
Hardware Revision 3
Firmware 7.1.2 build 4094
PepVPN Version 7.0.0

The issue i am suffering is that i am doing SNMP requests from a Zabbix server each second and i am getting values every 30 seconds.
Is there a way to have more granularity on the data?

Am i doing something wrong?

i have modified the title of the post as i made a mistake and i am not getting “0” values but only getting fata every 30 seconds.

Is there any way to improve the granularity?
