October 2021 - Dr. DMV's Troubleshooting Toolkit by Glenn Berry (@GlennAlanBerry)

Abstract
Dynamic Management views and functions allow you to easily see exactly what is happening inside your SQL Server instances and databases with a high level of detail. You can discover your top wait types, most CPU intensive stored procedures, find missing indexes, and identify unused indexes, to name just a few examples. This session presents, demonstrates, and explains a complete set of diagnostic DMV queries that you can easily use to detect and diagnose configuration and performance issues in your SQL Server instances and databases.
This session goes into exhaustive detail on how to interpret the results of each of the diagnostic queries, including relevant background information on how to properly configure your hardware, storage subsystem, operating system, SQL Server instance, and databases in order to avoid performance and scalability issues.
Prerequisites: Some experience with SQL Server 2005 and later
