You might want to check your PHP setting to see if you have 'safe_mode = On'...  please see the following post from Rene yesterday...

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

When you direct your browser to http://masternode/ganglia what do you see?  Do you see a ganglia page with no graphs (but there are other Ganglia wordings...) or no page at all?

Subject: [Ganglia-general] How to run webfront succesfully outside cluster?


I'v  installed gmond on every node of my cluser that is using OSCAR3.0 + Redhat 9.0, and installed rrdtool + gmetad + webfront on the Maser node .They worked well.
 
My Master node have 2 NIC, Eth0 with the IP 192.168.0.254 connect the compute  nodes in the cluser, Eth1with 10.0.0.1,connect a client ,which is running  Redhat9. And I'v installed rrdtool + gmetad + webfront. The web server workes well. But i can't see any node's information in my mozilla.
 
My Client ip 10.0.0.2. I'v added  route. Ping 10.0.0.1 and Ping 10.0.0.2 and Ping 192.168.0.254, they all work well. But i can't ping succusffully
192.168.0.X ,which is the compute node's IP  in my OSCAR cluster.
I've try to open the IP Forword in my Master node, the webfront still don't display my cluster's information.
 
So, How could i do?? Who can give me some advises?
Thanks!
