ERROR: unknown DS name ''

[golemb]

Hello;

I have modified the weather.php file to pull data from weather.com. The cmd.php poller is collecting the right information but I get an error "unknown DS name ''. I must have missed something in the datasource but I can't find it. I'd tried the weatherbug script but it has no data for Canada that I can access.

Thanks

Hi,

Remove the ":" character before wspeed

Good call Eric and I would tend to agree that the : might be the problem. I checked over all my datasources and templates but I have no idea where that extra : is coming from. I didn't enter it.

Fixed it, sort of by using the sledhammer method. Nuked the database and cacti directory and started from scratch. Second times a charm. Works great now. When I have it done I will export the xml files and post them.
