Performance Tuning with SQL Server Dynamic Management Views

Chapter 1: Using Dynamic Management Objects
Summary
Ultimately, it is the granularity of the data, and level of programmatic control, which
makes the DMOs such an important addition to the DBA's performance tuning
toolkit. DMOs do not necessarily replace other performance tools, but they do offer a
level of detail that is largely unavailable elsewhere, or at least from the native tool set.
Furthermore, you don't need to master a new GUI, or a new language in order to use
them; it's all done in a language every DBA knows and mostly loves – T-SQL.
Hopefully, this chapter has provided a brief, broad overview of the sort of data that
the DMOs covered in this book can offer. It is up the rest of the book to provide the
scripts, explanations and details that will allow you to collect the information you need
to troubleshoot SQL Server problems on your servers.
