[hobbit] help - still problems to see rrd graph

Fri Feb 10 21:08:32 CET 2006

Hi Marco,

Have you tried to look at the rrd file using rrdtool dump file.rrd ? 
this could give you an indication if its the rrd file that is the 
problem or the cgi program.

I am running RHEL 3 update 4 with this configuration

hobbit 4.1.2p1
rrdtool-1.0.49-1.1.el3.dag
zlib-1.1.4-8.1
libpng-1.2.2-25

which works.
