Hello,
Occasionally I have a problem polling data on one of my external Cisco routers. On the Internet-facing interface, the Inbound data is zero, but the Outbound counter is working. The reverse is same for my LAN-facing interface.
Log of external interface graph;
1232469272 1414085204 1166424532
1232469272 913636 0 913636 0
1232468840 1070413 0 1070413 0
1232468700 1068637 0 1070413 0
1232468400 1124656 0 1441579 0
1232468100 1441579 0 1441579 0
As you can see, one of the columns are zeros and that's what MRTG is graphing.
Debug log of the most recent poll (private data changed):

Is this an MRTG bug or something with the router itself?
