cleared up in the chat.

yep, good

maybe we should just reply the mean load of the whole cluster ?
like e.g. 
GOMD"server": ALL:445
or do you want to have this calculation in the libgomd ?
........just my thought is that we should have this calculation
in the gomd because it might slow down GUI applications
if we have it in the libgomd (imagine a huge cluster)

usefull, maybe not needed (the ranges). My suggestion is just
to report all values from all online nodes 
(mean values for the whole cluster). 
To my mind the client application will just need to get one value from
a special node by request or the mean value for the whole cluster.
Why do we need the ranges ?
( .... there may be a reason for it i did not see yet)
