Zabbix 2.2.2 graphs not showing up

[shall]

Hi everyone,

We had a Zabbix 2.0.6 installation that I upgraded to 2.2.2. The upgrade seemed to go well and the database upgraded, but now none of the graphs are rendering. I tried backing off to Zabbix 2.2.0 but no help. When I look at the console in Chrome it appears the Javascript thinks that it has some undefined variables:

body.scrollTop is deprecated in strict mode. Please use 'documentElement.scrollTop' if in strict mode and 'body.scrollTop' only if in quirks mode.
body.scrollLeft is deprecated in strict mode. Please use 'documentElement.scrollLeft' if in strict mode and 'body.scrollLeft' only if in quirks mode.
Uncaught ReferenceError: timeControl is not defined charts.php?sid=7cf0453ce58c4aab&form_refresh=1&fullscreen=0&groupid=0&hostid=10084&graphid=528:29
Uncaught TypeError: Cannot call method 'add' of undefined charts.php?sid=7cf0453ce58c4aab&form_refresh=1&fullscreen=0&groupid=0&hostid=10084&graphid=528:34
event.returnValue is deprecated. Please use the standard event.preventDefault() instead.
Calling LP_setval from A onloadwff.js:78

The lines of Javascript that seem to be throwing the errors are:

frontends/php/include/classes/screens/CScreenBase.php:                zbx_add_post_js('window.flickerfreeScreen.add('.zbx_jsvalue($jsData).');');
frontends/php/include/classes/screens/CScreenBuilder.php:             zbx_add_post_js('timeControl.addObject("scrollbar", '.zbx_jsvalue($options['timeline']).', '.zbx_jsvalue($timeControlData).');');

Any ideas?

What version of PHP do you have in place? Zabbix 2.2 requires the minimum version of PHP to be 5.3.0

Don't know if that will help or not. Other requirements are listed here under "Frontend" category

The Zabbix server is running on a SLES 11 SP2 host. When I performed the install the Zabbix webpage installer stopped me because the default PHP on the machine was < 5.3.0. I used the newer PHP 5.3.8 rpms provided by SUSE though, and the installer let me through:

hpczabbix01:~ # rpm -qa | grep php | sort

Maybe have a look at the folder permission, and check apache error/access logs which might give you more insight then the chrome console.

I would try testing in Firefox, If Chrome is unable to load an image it hides it from the page, Firefox should show the image placement with the red X placeholder indicating the image couldn't be loaded, right click and copy the image url and try and load the graph directly. Check logs to see if you can track what is going on.

Graph URL is normally something like this: http://<zabbix hostname>.com/chart2.php?graphid=2625 (change graphid to valid graph.)

Thanks for the ideas. I've already found a workaround for the issue in my other post that solves both of my issues: https://www.zabbix.com/forum/showthread.php?t=44353

I ran chmod -R on the entire frontends/php tree so Apache had access to everything. The apache access/error logs didn't seem to tell me anything useful.

I tried in Chrome, Firefox, Safari, and IE - none of them showed any sort of missing picture. I never did find any useful server or client side logs that led me much of anywhere.

The only reason I thought to try a new OS was that I had a stable Zabbix on SLES 11 SP2 before the upgrade, and during the upgrade the only thing I upgraded other than Zabbix was the PHP, so I figured I'd better try something else that might work in a slightly different way.

Update PHP

Had this with SLES 11 SP2 installing 2.2.4 and it is definitely PHP related. I downloaded the PHP 6440 upgrade from Novell.

http://download.novell.com/Download?buildid=qYz-7P4ZgkY~

http://support.novell.com/security/cve/CVE-2012-2335.html

Upgraded the PHP to 5.3.8-0.33.2 and everything started working correctly.
Hope this helps someone
