Graphing SUM Data / Agregate Traffic

Graphing SUM Data / Aggregate Traffic

I am trying to graph data (interface in/out) and combining these results from a “number” of interfaces. The goal is to have Cacti to SUM or provide aggregate numbers for these separate interfaces into a single graph. What I am noticing is that before I even add multiple sources… Cacti is only providing a faction of the real data. See my attach screen shot for details. Basically, int Gi0/25 is a fiber uplink to a provider, measuring ingress / egress traffic… The bottom graph in red, is pulling data from 0/25 same interface and graph data on the outside… however you can see there’s a large difference it what it is seeing compared to 0/25… any ideas why this might be?

You need to apply the bytes to bits CDEF on your combined graph for each element of it.
