Try increasing your SNMP timeout for that host. I had this, with disk stats specifically, where it has time to give one of the results but not the other, for some strange reason.

If you zoom in on the graph, I'm pretty sure you'll see that they are gaps, just only in one variable.
Weathermap 0.98a is out! & QuickTree 1.0. Superlinks is over there now (and built-in to Cacti 1.x).
Some Other Cacti tweaks, including strip-graphs, icons and snmp/netflow stuff.
(Let me know if you have UK DevOps or Network Ops opportunities, too!)

How do you increase the snmp timeout on the host if its a windows based machine?

Same as on any other... Console..Devices..click on the host, and then increase the SNMP timeout to (say) 2000ms.

Yeah looks like its that. Thanks Howie your a star!, I set it to 1000ms and I only get a few glitches now. I Will try 2000ms and see what happens. Bit worrying though i've only added one host, could be an indication of some networking issue possibly?

No I think some things just take a little longer for the SNMP agent to figure out.
