Hi all

Does anyone has a problem with mrtg-rrd cgi generating wrong Y values?

Say I got  2 Gig / partition

the value that it returned for total size and used space is correct
ie Total size: 2048MB  and Used: 920MB

but on the Y graph display 1M-2M instead of 1G-2G  or 1000M-2000M

attached is my MRTG config for this diskspace section and the graph
(have a look at the Y section of the graph).
I also have a similar problem with memory with Y values

ps:sofware and platform
Solaris 8
Latest current MRTG and RRDtool and mrtg-rrd.cgi
Net-snmp 5.0.4 pre 2 ....(stable 5.0.3 keep crashing on my box if I have
host mib compiled in)....
and another thing if I use MRTG without RRDtool and mrtg-rrd.cgi it displays
correctly in  1000M-2000M
