That said, for the margin of error to be _that_ large seems a bit peculiar to me. Maybe some major packet never made it, and RRDTool assumed a value of 0 due to a lack of data? I think you can trust the values that SAR is reporting you, although determining why Ganglia gave this value instead (and on just bytes out, no less, as the bytes in metric looked fine for the time period) might be useful. -- ~Mike - Just my two cents - No man is an island, and no man is unable.
