Executive summary report for Usage

currently i don't see any template where i can get detailed usage report of customer (i.e. Group) with details of CPU, Memory, Disk, Network in single report.  there is an option we can do with device metric trends but we have enter all Data points which is going to be a huge task when we are talking about multiple groups who's with huge amount of servers.   There has to be templates around to get execute summary  (Management, CIO reports) with details of monitoring system and few for utilization like this.. etc..
