[Solved] Cacti not showing Nginx graph

Post by belgianguy »

Hi, I set up an Ubuntu 12.04 Server with a Nginx webserver and wanted to use its statistics to show up in Cacti.

Cacti is version 0.8.7i, the poller I'm using is spine.

I'm trying to use the following templates: http://forums.cacti.net/about26458.html

Those perl scripts work from the commandline so the server reports its data and the scripts are correct, but it seems I'm still missing something to make them work in Cacti.
What I do have noticed is that they don't have their own rrd's being generated/filled, so I guess it can't collect data at all then.

Another error I've noticed is that in the Debug Mode of the Graphs Management it states the following:

For the Client statistics:

The graphs show up as broken images, where the rest of the graphs (Memory Usage, Processes, ...) all show up fine.

What am I missing here? If any other information is required, feel free to say so!

Solution: An analogy to this http://bugs.cacti.net/view.php?id=1265, in short, the DEF statements aren't created through the "Add" dialog, I had to create them through Device > Localhost > Create Graphs for this device
