This is likely the snmp agent on the device you are monitoring. It's likely only updating it's information every X seconds. So, the graphs will appear choppy in that case. Some older devices especially only update the interface metrics once every 15 seconds. Certainly back when I was in the business, over 15 years ago.

I am monitoring an ISR router and this is not an old device. when I took that off I see traffic is continuous. I have this problem for most of devices are ISR's. I don't see this problem for IOS router like.
