Not all graphs showing

[jclark]

Before I spend the time digging into the code itself I figured I would ask here to see if this is a common problem and already known and solved. I just downloaded and installed version 1.0.

Setup:

Debian
linux kernel 2.6.8
php 4.1.2
mysql 3.23.49
apache 1.3.26

The problem is that not all the images are created successfully. After testing a few things I find this.

PHP pages that generate images:
chart_diff.php
trend.php
chart3.php
chart5.php

PHP pages that fail to generate images:
chart.php
map.php
chart2.php

I am looking for the relationship between the stuff that fails.

Since I have just installed there is always the strong possibility I have something configured incorrectly. Looking for suggestions.

I'm sure you have everything correctly configured.

The problem is obviously related to wrong version of GD library compiled into PHP.

Do the following in include/classes.inc.php:

Uncomment this line:

//					 Header( "Content-type: text/html");

and comment this one:

					 Header( "Content-type: image/png");

Then try to view chart.php in a browser. You will see self explanatory error or warning messages.

Thanks Alexei for the quick response. This project obviously has required lots of work and if I get things working the way I would like, it will save me huge amounts of time. I appreciate the effort.

I'm sure you have everything correctly configured.

The problem is obviously related to wrong version of GD library compiled into PHP.

That would have been my first guess *if* the other images weren't created successfully. Output from phpinfo:

GD Support enabled
GD Version 1.6.2 or higher
FreeType Support enabled
FreeType Linkage with freetype
T1Lib Support enabled
JPG Support enabled
PNG Support enabled
WBMP Support enabled

Do the following in include/classes.inc.php:

Uncomment this line:

//					 Header( "Content-type: text/html");

and comment this one:

					 Header( "Content-type: image/png");

Then try to view chart.php in a browser. You will see self explanatory error or warning messages.

Tried that. The only output generated is the header itself. Nothing else.

I have a bit of php experience and may spend a little time playing over the weekend. I will let you know what I find.

Thanks again.

Hi there.
I had the same problem (or the same symptoms considering a different problem).
Maybe this seems too obvious, and maybe you've already done that, but in my case it helped to go through the MySQL's Zabbix database and examine-fix all the tables (I did it with PHPMyAdmin and afterwards once again with "myisamchk").
Well... maybe that's not the answer you were looking for, but it's an answer
Bye
