One of the most important conclusion of the analysis of the results of CCRC08 and operational experience after CCRC08 is that the LHC experiment specific monitoring systems are the main sources of the monitoring information. They are widely used by people taking computing shifts. They are the first ones to detect the problems of various nature. Though these systems provide rather complete and reliable picture of the computing activities of the LHC experiments on the Grid, the diversity of these tools creates certain problems. It is very difficult for non expert users to find required information. It is not always possible to correlate information coming from multiple sources. Currently there is no high level view of the computing activities of all LHC experiments. The talk will cover current development aiming to provide such view using information from the experiment specific monitoring systems.
