I there a way to subscribe to changes in sensor values? e.g. be notified when disk space %, or cpu %, changes? Do they raise events you can subscribe to?
Instead of checking many 1,000s of sensors every 20 seconds to see if they have changed (and find most haven't), it would be much more efficient (and quicker) to just be notified of the ones that have when they do.
I've been reading through about notifications, triggers, and such like, but its not clear if that is what they are talking about.
I'm using the PRTGApi to build a C# application to do process the changes.
