Funnily enough I am looking at the Hobbit code that deals with RRD data at the moment. If you are using the NCV capabilities then it looks like you can't have negative numbers. The generic NCV (Number, Colon, Value) code looks for numbers only, no signs (somewhere near line 70 in hobbitd/rrd/do_ncv.c):
val = l + strspn(l, " \t");
l = val + strspn(val, "0123456789.");I have no idea if RRD is able to accept/store negative values, but if it is, it should be a simple case of adding the + and - characters to the last line listed above to make what you want possible.

Hi all, None of my clock offset graphs graph anything when the clock offset from
a host is a negative number. Only positive number work. Anyone having the same thing happen or know how to fix?
I'm running a snapshot 4.3.0-0.20080103
Thanks David
