Map not generating when nodes are present.

Post by briodan »

I recently did a new installation of Cacti and the plugin for Weathermap and it's not generating maps when i add a node in the map. The maps generate fine if i add the legend for example but no nodes.

Here is the logfile generating when i'm using the default included simple.conf config file

Code: Select all

01/06/2010 09:58:36 AM - WEATHERMAP: Poller[0] [Map 5] Example.conf: About to write image file. If this is the last message in your log, increase memory_limit in php.ini [WMPOLL01]  
01/06/2010 09:58:36 AM - WEATHERMAP: Poller[0] [Map 5] Example.conf: Map: /usr/local/groundwork/apache2/htdocs/cacti/plugins/weathermap/configs/simple.conf -> /usr/local/groundwork/apache2/htdocs/cacti/plugins/weathermap/output/a1bb0b0d4d559a2e8221.html & /usr/local/groundwork/apache2/htdocs/cacti/plugins/weathermap/output/a1bb0b0d4d559a2e8221.png  
: Poller[0] Weathermap 0.96a starting - Normal logging mode. Turn on DEBUG in Cacti for more information  
01/06/2010 09:58:36 AM - WEATHERMAP
This the the log generating when i edit the config fiel and remove all nodes and links

Code: Select all

I am also getting the following notice message when i go to the weathermap tab, not sure if it has any impact or not:

Code: Select all

Notice: Undefined index: action in /usr/local/groundwork/apache2/htdocs/cacti/plugins/weathermap/setup.php on line 147

So when you got

Code: Select all

01/06/2010 09:58:36 AM - WEATHERMAP: Poller[0] [Map 5] Example.conf: About to write image file. If this is the last message in your log, increase memory_limit in php.ini [WMPOLL01]
as the last message in your log, what did you think? :-)

You should also run check.php and check-gdbug.php from the command-line - older Ubuntu versions suffer from a particular GD bug which might also cause you problems.
Weathermap 0.98a is out! & QuickTree 1.0. Superlinks is over there now (and built-in to Cacti 1.x).
Some Other Cacti tweaks, including strip-graphs, icons and snmp/netflow stuff.
(Let me know if you have UK DevOps or Network Ops opportunities, too!)

OK - and the check-gdbug.php?

I don't remember which Ubuntu release fixed the bug, but Edgy (7.1) definitely had it.

running check_gdbug.php results in the following:

Code: Select all

Some version of the GD graphics library have a bug in their handling of Alpha channels. Unfortunately, Weathermap uses these to draw Nodes. 
This program will test if your PHP installation is using a buggy GD library. 

If you are, you should either use PHP's built-in (aka 'bundled') GD library, or update to GD Version 2.0.34 or newer. Weathermap REQUIRES working Alpha support. 

Let's see if you have the GD transparency bug... 

If you see no more output, or a segfault, then you do, and you'll need to upgrade. 

If you get other errors, like 'undefined function', then run check.php to make sure that your PHP installation is otherwise OK. 

Here we go...
I have tried applying the patch in the sticky and removing gd and reisntalling through apt but that did not fix the issue.
Looks like php is using an external gd library, i'll see about recompiling.
