Microsoft have released many DMV & DMF for every release of its new SQL Server release. This has helped every administrator and developers a VERY BIG HAND in sorting out many problems. The days in writing our own scripts are now over and these DMV’s also provide support for almost all areas no matter whether it is to do with sessions, tables, indexes, Operating system, I/O. All are now taken care. Below I am providing some of the DMV’s that might be helpful for you.
