Please visit the raph at graph management, switch to debug and post resulting rrdtool graph statement

Not uncommon to have both inbound and outbound the same on an interface if that particular interface is both the inbound and outbound path for the traffic in question.
An example is the classic 'router on a stick' scenario, where all traffic goes to the router, only to be routed back out the same interface in situations where multiple IP subnets are in use on the same physical environment, or where Vlans are used, and the interface has sub-interfaces that route between each other, but, again, the physical path is via the same link.

What kind of device is this?
Based upon the name of the rrd file, is that a carrier class chassis? (slot19 ??!!) Is that an old Cisco BPX or something

I guess the question(s) would be: What is the expected graph result? Is that not the expected traffic flow?

It's occuring on all my graphs not just one. These are on various different interfaces. Routers that are core routers, edge routers, etc.

That graph there is a DSL Multiplexer uplink which has typically more input than output since subscribers download more than they upload.

The graph definitions are fine.
Now, please check the "System Utilities -> View Poller Cache" to find the OIDs used to fill that very rrd file. Please post both entries you find there.
