The headline is about the data processed on their compute, the amount of data in the monitoring system is considerably smaller (but still not small data): > But Brij Kishor Jashal, a scientist in the CMS collaboration, told The Register that his team were currently aggregating 30 terabytes over a 30-day period to monitor their computing infrastructure performance. So 1 TB / day, that's about 10 MB/s.
