PHP error with weathermap-cacti-plugin.php

[sartoph]

Hi,
I've just installed the Weathermap 0.97a plugin on Cacti 0.8.8 / PA 3.1. I've run into the following error in I'm unsure how to resolve. I tried installing this same plugin in a test install I have of 0.8.7i / PA3.1 and had no issue at all. The plugin architecture seems to be ok and I can see a couple references to weathermap in the plugin_realms table in MySQL.

Any ideas?

Do the weathermap_maps and weathermap_data tables exist?

Hi,
Thanks for getting back to me. Doesn't appear so, attached image is of the cacti sql db from both copies, one of the left is from cacti 0.8.8 and the right 0.8.7. Interestingly, though I'm not getting the php error in the 0.8.7 version, I can't seem to add / edit anything in the weathermap plugin, presumably because of no weathermap tables being present.

Hey,

Did you manage to fix the problem? Seems I have the same with cacti 0.8.8a and weathermap 0.97a, activating the plugin does not create the database/tables needed for it to work. I can use the editor, but I am unable to create maps.

Thanks!

[edit]

I install the plugin by copying the weathermap directory into plugins/ then do the "Install Old Plugin" available in the "Plugin management" page. It gets properly loaded and I can see "WEATHERMAP" tab in cacti, but nothing happens since the database table creation process does not work.

Cacti user has permissions to create tables:

Db: cacti
User: cacti
Select_priv: Y
Insert_priv: Y
Update_priv: Y
Delete_priv: Y
Create_priv: Y

Found the solution in:

along with adding the weathermap_settings

This will be fixed in 0.97b - nearly ready!
