I am looking at the possibility if monitoring Moodle information like the number of users connected, when a teacher modifies a class, and other internal data from Moodle. I want to monitor using OpenNMS. It can pull data using HTML. I've seen examples on pulling eBay auction prices, weather data and stock prices from web sites. Can anyone conceive of a way to pull report data from Moodle so it can be monitored externally?
