[Ganglia-general] CPU last hour graph

[Jones George]

I am monitoring some windows hosts using unicast but for some reason,
the data_source host has all the graphs showing up including the CPU
last hour
summary graph.. but all the other hosts that are feeding into the
data_source 
host does not display the CPU last hour graph.. does anyone have any
idea
why this is happening?
 
Thanks for any input..
