 |
|
After install the weathermap in cacti, I found the weathermap icon display in the cacti menu.
And when I access http://localhost/cacti/plugins/weathermap/editor.php
I received some error message shown as below.
NOTE: This editor is not finished! There are many features of Weathermap that you will be missing out on if you choose to use the editor only.These include: curves, node offsets, font definitions, colour changing, per-node/per-link settings and image uploading. You CAN use the editor without damaging these features if you added them by hand, however.
when I created the map ,I also received the error message.
Fatal error: Call to undefined function imagecreatetruecolor() in C:\Inetpub\wwwroot\cacti\plugins\weathermap\Weathermap.class.php on line 2962
I have gave the "configs" and "output" folders permission to the webserver user.
Pls give some advice ,Thanks

Probably, you don't have the GD module for your PHP installation. Try running php -m from the command prompt, and look for 'gd' in the list.
How to enable the module depends on your PHP install. Sometimes it's provided but disabled by default, other times you will need to download something extra or even compile it.
(0.9 will make this error more obvious - it's supposed to tell you that the module is missing, like the main weathermap poller plugin does)

Do you have more than one php install? It's possible that your CLI php interpreter is not the same as the mod_php one. The normal weathermap/poller stuff uses the CLI php. The editor uses the mod_php, as it's a web page  I'm assuming that the plugin part is working for you (does the example.conf work if you add it to the list of maps?)
I believe some earlier versions of GD did not support truecolor either, so you might need to upgrade GD, then recompile/upgrade the php install to use it.
I would start with:
and see if you have more 'php' executables that you expect.

OK - I'll try and add some more explanation to this error message in future.

There isn't a specific fix - it depends on your installation!
You need to be sure that both the CLI PHP interpreter and mod_php have the gd module loaded. The normal poller-process weathermap plugin runs from the CLI, but the editor uses mod_php (or the ISAPI module for IIS), to draw the map.
Sometimes, the two different PHP modes have different php.ini files. Sometimes, you can have two PHP installs without realising it (e.g. one from RPM + one from source in /usr/local). To see what you have in mod_php, you can create a page with the following contents:
| Code: |
<?php
phpinfo();
?>
|
and go to it in a webbrowser, which will tell you what modules are loaded, and where they are loaded from.
