Report faulty tracking eg. when ecommerce order grand total is zero

[ryrun]

I was wondering, why my ecommerce tracking wasn't working correctly. It was tracking the orders, but didn't show anything in the ecommerce stats. I found out, that the grand total in the tracking code was zero in some cases. I fixed it, now everything is fine.

But is it possible that piwik alerts this kind of faulty tracking in the backend, similar like google analytics?
Could be a new feature.

I think you'd be interested in #7550 which is not implemented yet.

We can maybe still leave this issue open to make sure that when working on #7550 we handle this case to make sure such a faulty tracking would show up in whatever notification system we will develop some day.
