Re: [BackupPC-users] backuppc 3.1.0-4/debian: rrd graph missing

Hi Jonas,

I am still pretty much a newbie at Linux, but I am getting better each
day.  I am currently running a small network of less than ten machines
and have one machine that is my Archiver running BackupPC 3.0.0-4
Ubuntu1.  I, too, wanted to have a graphical representation of my
backuppc strorage drive.  I run gkrellm to monitor machine parameters
such as voltages, fans and temperatures.  It also allows me to monitor
my drive space both internal drives and remote shares.

While this does not answer your question about the graphing in the cgi
interface, it does give you an easy work-around until you get the issue
resolved.  -- ken
