ifOutOctets / ifInOctets Total monthly / weekly?

[shlomia]

Hi, I'm monitoring my fortigate interfaces by collecting ifOutOctets / ifInOctets per second.
I would also like to get information regarding the monthly / weekly bandwidth.
But when I got to my graph I can't see the total, I can only see the max,avg,min and per second.
How can I calculate the monthly / weekly total in each interface?

Thank you

What if I create a "Calculated" item of my ifOutOctets per second? I can calculate the last 60 values or something like that? Right now I have an item that show me ifOutOctets per second, and the interval is every 1 minute. So I can calculate the last 60 values to get 1 hour bandwidth and so on?
