We have performance dashboard reports (SQL 2008 R2 ) to get current state of the system i.e. including cpu, resource waits etc. but is it possible to alter it to get it working for past periods. i.e. if we have kept archived copies of DMVs, would it require changing any of the SPs?
I saw in a few forum questions that a few custom reports can be built using RDL. Appreciate if you can redirect me to a few resources needed for the above requirement as I haven't got much experiencing working with RDL.
Thanks.
