Martin and Ramon,
Greeting.....
"Before you read this just want tell you that its working now.....
Ofcourse you get the credit for giving hints and suggestion..... This is
what I was doing "
I am still in the learning phase, so please forgive me if I don't
understands or miss obvious things.
I had php-gd, gd and gd-develop
# rpm -qa | grep gd
gdm-2.6.0.8-16
gdbm-devel-1.8.0-25
sysklogd-1.4.1-30
gd-progs-2.0.33-2
gdbm-1.8.0-25
*gd-2.0.33-2*
*gd-devel-2.0.33-2*
gdk-pixbuf-0.22.0-18
*php-gd-5.0.4-10*
gdb-6.3.0.0-1.21
While I was testing gd support "php -m"
I got this error in the first line..
[ ~ ]php -m
PHP Warning: Module 'gd' already loaded in Unknown on line 0
[PHP Modules]
bcmath
bz2
calendar
ctype
curl
dbx
dio
dom
exif
ftp
gd
...........conti..
Remember Martin, you asked me to add extension = gd.so in php.ini file..
I removed that line and restarted Apache, and Got my pie chart...
Now I have got one more strange problem..
I addded 31 nodes to the cluster, and it was showing all the nodes by
hostnames, Yesterday nigh I added three more nodes, which are basically
replication of other 31 nodes. Copied gmond.conf file from on old node
to new nodes. Added entries in gmetad.conf Restarted gmond and gmetad.on
master and gmond new slave nodes,
I was able to see new nodes but they dont show hostnames, they Display
IP Address. Any Guess, what might be wrong.. DNS, Hostname
configuration, netwrok configurations are fine.
Thank you so much for you help and support...
Please let me if I can contribute in some kind of Documentation.

Martin,
Hehe, yes. PHP is not case sensitive about function names.
The idiot who decided that should be shot imho. ;)
It seems PHP requires some sort of GD library to be able to use the
image** functions.
From the website http://www.php.net/manual/en/ref.image.php:
-- start --
If you have the GD library (available at http://www.boutell.com/gd/)
you will also be able to create and manipulate images.
The format of images you are able to manipulate depend on the version
of GD you install, and any other libraries GD might need to access
those image formats. Versions of GD older than gd-1.6 support GIF
format images, and do not support PNG, where versions greater than
gd-1.6 and less than gd-2.0.28 support PNG, not GIF. GIF support was
re-enabled in gd-2.0.28.
Note: Since PHP 4.3 there is a bundled version of the GD lib. This
bundled version has some additional features like alpha blending, and
should be used in preference to the external library since its
codebase is better maintained and more stable.
-- end --
This is also poorly documented from the PHP side I think
The problem is the last part I think, that it's bundled nowadays. Some
developers might assume that it's not a prereq because of this.
However some distributions and packaging systems seperate php and gd
from each other anyway, for example with Debian you don't get php-gd
by default.
I agree the prereqs could use some additions in the Ganglia's
documentation, let's put it on the todo list. ;)
Cheers,
- Ramon.

Jai,
Ramon is right. You are at least missing "php-gd". I could reproduce
your problem on my FC4 installation. I did not get the pie charts also.
Installing php-gd via yum and restarting Apache solved the problem. You
may also need "gd-devel", which provides /usr/lib/libgd.so.
Check with "php -m" or the following small php-web-script:
[EMAIL PROTECTED] html]# cat >> /var/www/html/phpinfo.php
<?php
// Show all information, defaults to INFO_ALL
phpinfo();
?>
Both should show "gd support" in some way.
You can forget my E-Mail regarding case-sensitivity. I just found out
that (unlike almost everything else) function names are not
case-sensitive. Weird decision. I know why I do not like PHP that much
...
Cheers

That means you are still missing libgd and the php-gd extension, as I
mailed before.

Dear Jai,
good to hear that 3.0.2 fixed most of the problems for you. I am
not
sure about the PIE stuff, but there should be some error messages
in
the log-files of you r web server. They could give you a hint. And
there still may be PHP bugs preventing 5.0 to work correctly. As I
said, we want to know.
Cheers
Martin

Thanks Martin,
Upgrading to 3.0.2 worked just fine. Still missing PIE though,
but I
guess I am missing some package for that...
Thank you so much,
