Graph is not showing actual details

[neel27]

HI All ,

I am using cacti for long time and recently our cacti server got crashed , I have rebuild the same and added the devices. I added our co. router on which there are multiple ISP linked. After adding device and enabled graph for the same. What I am seeing is the graph showing on cycle is not same as actual inbound/outbound traffic.

If I see them in realtime it is showing approx. same but on regular graph there is no match with actual running traffic. Like in actual traffic for inbound/outbound is 30/150 but is regular graph it is showing till 20 MB .
