Do you not have the emails reporting status set up? I get emails about machines that haven't backed up for a few days and also emails showing change in size or number of files of the dataset. Usually keep a bit of an eye on it.

I think it can do twitter too.

Note I'm using the paid version and it's v4.8. I wasn't aware there was a new stream. I wish they'd make some native clients though. Java is not my favourite.
