The document discusses Windows Management Instrumentation (WMI) and how it can be used by command line database administrators and SQL Server. WMI provides an interface to access operating system data and events. It allows tapping into data that was previously difficult to access from SQL Server, as well as responding to events. The document outlines WMI architecture and tools that can be used to access and query WMI data, including WQL which is similar to SQL. It also gives examples of how SQL Server and SSIS can consume WMI data and events.

2. WMI For Command Line DBA Session Agenda WMI Tools and Utilities What is WMI? SQL Server as a WMI Provider Why use WMI? A WQL Primer Technologies in Play SQL Server as a WMI Consumer

3. What Is WMI? An overview of WMI What is Windows Management Interface? Extension of windows driver model that provides an OS interface to information and notifications WMI is Microsoft's implementation of the Web-Based Enterprise Management (WBEM) and Common Information Model (CIM) standards from the Distributed Management Task Force (DMTF) WMI and SQL Server SQL Server as a provider SQL Server as a consumer SSIS as a consumer

4. Why Do I Care About WMI? Benefits of tapping into WMI Access OS data that was previously hard to get from SQL Access trace data without running a trace Log DDL events Add better intelligence to expensive queries Respond to events in SSIS Augment your monitoring system

7. WQL Overview Hey, that looks familiar… Subset of ANSI SQL Event query example SELECT * FROM __InstanceCreationEvent WITHIN 10 WHERE Targetinstance ISA "CIM_DirectoryContainsFile" and TargetInstance.GroupComponent= "Win32_Directory.Name=\"e:\\\\temp\"" Data query example Select * from Win32_NTLogEvent Where Logfile = ‘Application' and EventType = ‘error' and SourceName like ‘%SQL%’
