Online monitoring for the CDF Run II experiment and the remote operation facilities

The foundation of the CDF Run II online event monitoring framework, placed well before the physics runs start, allowed to develop coherent monitoring software across all the different subsystems which consequently made maintenance and operation simple and efficient. Only one shift person is needed to monitor the entire CDF detector, including the trigger system. High data quality check is assured in real time and well defined monitoring results are propagated coherently to offline datasets used for physics analyzes. We describe the CDF Run II online event monitoring system and operation, with emphasis on the remote monitoring shift operation started since November 2006 with Pisa-INFN as pilot Institution and exploiting the WEB based access to the data.
