Dear Rene and Bernard,
I managed to obtain a copy of rrdtool, but itself needs
further software for a RedHat 9 box.
[EMAIL PROTECTED] kits# rpm -Uvh rrdtool-1.0.48-1.i386.rpm

To cut the story short, I have loaded the following:

I have also edited /etc/php.ini to make these changes:
safe_mode = On
safe_mode_exec_dir = /usr/bin
where /usr/bin/rrdtool is loaded.
I restarted gmond, gmetad and httpd.
Same result, ie. no graphs produced.
In /var/log/httpd/error_log, I found these:

Still not quite right. What have I missed?
Is there any good recipie to mount all these software for RedHat 9/RHEL ?

Hi,
I had a similar problem so I hope this helps. It had to do with the default
install of php to safe_mode = On. This will not allow you to run executables
like rrdtool to generate the graphs unless they are in the
safe_mode_exec_dir=/path-to-somewhere/safe_mode_exec_dir or something like
that.
Just set these variables in you php.ini file. Then either copy rrdtool or
make a simbolic link to your safe_mode_exec_dir
look in your http/logs/error_log file you should see something like
sh: /rrdtool: not found
sh: /rrdtool: not found
sh: /rrdtool: not found
Once you set your safe_mode_exec_dir this should go away and the graphs
should show up
Hope it helps
Rene
