Consistent gaps in all graphs

[chand]

I've attached an image of how my graphs have been coming out since installing the most recent version of Cacti. After a quick search on here, I haven't found anything. My logs are clean other than warning of the following:

I haven't had any luck in researching these errors through Google.

The gaps are likely to be either the Cacti host server being extremely busy (check the disk i/o, processor useage etc) or more than likely the remote device either not responding or being slow to respond.

Oh and also use the data source debug tools to check if there is a minimum/maximum limits as any values outside are basically ignored. So if it is consistently outside of it and no value is collected for the entire heartbeat, an unknown value is created which results in the gaps. Check the data source info and look at the heartbeat to know how long that can be:
