Hi Cynthia,

Yeeeah, I got a reply! ;)
Indeed, I do have a 2.6 kernel (uname -a gives
I have Orca 0.27, which is the latest stable version.
Perhaps I need this?

Do you know if I can just configure/make/install the snapshot over the 0.27 version?

I think I recognize this symptom. Are you running at Linux 2.6 kernel?
There were changes to the output format for some of the /proc
stuff. If you are running the latest version of orca and still have
the problem, reply to the list and I'll see why my install is working
on both types of kernels.

One thing I noticed is that some of the generated graphs are blank - all data is always zero.  This includes the "Disk System Wide Reads/Writes Per Second" graph, which I would really like to see, in order to get an idea about the disk activity.
