Automatic Tuning In SQL Server

Bob Ward has a post on automatic tuning in SQL Server 2017:

One of the key points I’ve been making to our customers about SQL Server on Linux is that the core database engine is the same as on Windows. Since Automatic Tuning is built into the core database engine, this feature works exactly the same on SQL Server on Linux.

As you watched my demo of Automatic Tuning for SQL Server on Windows, I used the Windows Performance Monitor to show the workload performance when automatic tuning corrects a query plan regression problem. But what about Linux? Windows Performance Monitor will not work with that platform.

Turns out I have some smart people working with me at Microsoft. I got help from Pedro Lopes from our Tiger Team and the engineering team who built SQL Operations Studio to show automatic tuning using that tool.

  • Pedro helped me build scripts that would query the DMV, sys.dm_os_performance_counters, which runs on SQL Server on Linux as it does on Windows (because it is built into the core engine). These scripts store results from this DMV in a temp table, and then query the temp table.

  • The folks at SQL Operations Studio showed me how to collect the result set from the temp table in a manner that would allow me to show the data in a Time Series chart in the tool. Kind of like a static perfmon chart of SQL Server counters.

With a bonus shout out to Tracy Boggiano.
