[mrtg] Re: rrdtool fetch doesn't match graph

[Bishop, Dean]

no.  i wondered about this but it does not seem to be the case

i have been trying to figure out any standard difference but can't.

rrdtool		graph
used space	7.36G		6.86G		7366408Bytes
free space 93.41M		89.15M	93164Bytes

i just can't find the correlation.

thanks,
dean

ummm.... this is a complete WAG, but are you off by a factor of 8 anywhere?
Remember, MRTG's main job was to graph bandwidth traffic, and you may be
confusing your bits with your bytes...
