That's odd, the CPU and MEM charts are working OK for me. It's just the load-avg that is missing (which causes the host to be marked "down").
For troubleshooting, if you intercept the sFlow feed with sflowtool (http://www.inmon.com/technology/sflowTools.php) then you can see what the numbers look like. The graphical freeware tool sFlowTrend is an option too. (http://www.inmon.com/products/sFlowTrend.php). How frequently would we need to poll the Processor Queue Length to get a reasonable load-average estimate? If we could get away with only doing it every few seconds then it might be worthwhile (perhaps a random delay would be appropriate) but I suspect you might have to poll much faster than that to get something worthwhile?
