Setting Fortigate OID with ELK

Hi Sir

I want to setting Fortigate bandwidth chart in ELK.

And refer the following img that is the chart in my Fortigate.

Then I have collect OID in ELK :
1.3.6.1.2.1.2.2.1.10
1.3.6.1.2.1.2.2.1.16

And Setting the chart in ELK

But looks like it is different.

Why is it different between two chart?
Does Fortigate chart is not using this OID?

BR,
Jim

Does anyone know how to config this chat?
