PHP error log in relation poller

[Phill_rutland]

Hi there,

I'm new to using Cacti and have installed this via the most recent windows installer package. I'm having issues with no graphing data showing or a test device I have setup. I have tried many possible solutions to no avail and read the Post Install guide along with the FAQ's. This is the error messages i'm getting in 'php_errors' log file;

[04-Feb-2011 15:40:30] PHP Notice: Trying to get property of non-object in C:\inetpub\wwwroot\cacti\lib\database.php on line 226
[04-Feb-2011 15:40:30] PHP Fatal error: Call to a member function close() on a non-object in C:\inetpub\wwwroot\cacti\lib\database.php on line 231

[04-Feb-2011 15:45:30] PHP Fatal error: Call to a member function close() on a non-object in C:\inetpub\wwwroot\cacti\lib\database.php on line 231

The timing are in relations to my poller but I can't for the life of me think what is causing the issue. I ran the graph debug and results returned fine;

RRDTool Command:

OK

Hopefully someone can help me, many thanks

forgot to add....

Operating System - Windows Server 2008 R2
Web Server - IIS 7
-Cacti 0.8.7g
-Spine 0.8.7g
-PIA 2.8
-MySQL 5.1.50
-PHP 5.2.14
-Net-SNMP 5.5.0.2
-RRDTool 1.2.30
-GetIF 2.3.1

PIA 2.9 is the latest which contains all the 0.8.7g patches.

Is this a fresh install of cacti?
Php -m show any errors?
The cacti technical support page show any errors?
Cacti.log show any errors?

[Phill_rutland]

So you advise upgrading to 2.9 may resolve this?

I can confirm this is a fresh install of Cacti. When I run the php -m command from the command line it returns no errors.

I checked the Cacti log and their is multiple warning messages that relate to a SNMP timeout (which is another issue I need to resolve) but i don't think this is in relation to the graph data not showing? as at the moment I have only setup Cacti 'downed host detection' to ping the host device. I have attached the Cacti log. I have checked the technical support page and I can't identify any areas on this page. I have attached this anyway. (had to attach as text as HTML is blocked)

Would you advise using Spine to be set as the default poller or cmd.php?

As you can tell I have very limited knowledge of this software. Only knowledge i have gained is from reading the forums, FAQ's and user guides.

PIA 2.9 contains the following patches: http://www.cacti.net/download_patches.php

For new installations, cmd.php is far less problematic.

Have you read through the debugging guide yet? http://docs.cacti.net/manual:087:4_help.2_debugging

[Phill_rutland]

Hi, I will try the debugging process and let you know.

The web link that refers to the latest patch releases however I thought these would have been included in the newest release which I did download -1.95 2010-09-23 , the most recent patches refer to a date in September?

[BSOD2600]

Nope the 1.95 installer doesn't contain the latest patches. I'm not inclined to update it as there is talk about 0.8.7h being released soon™ and it takes me a considerable amount of time/effort; all in my free time.
