DARKNESS

WMI

• WMI is an acronym for Windows Management Instrumentation– Registry, File and Disk systems, Services and

processes, Printers ,Networking, IIS, Performance Counters

• WMI Provider For Server Events– The WMI Provider for Server Events lets you

use the Windows Management Instrumentation (WMI) to monitor events in SQL Server.

Windows Management Instrumentation Query Language

• SQL ANSI with WMI-Specific Extensions• SELECT { event_property [ ,...n ] | * } FROM event_type WHERE where_condition

EVENT QUERY LANGUAGE

SELECT <Propertie-List> FROM <Event-Class Name> <WITHIN Seconds> WHERE <Instace-State> ISA '<Wmi-Class Name>'

"select * from __InstanceModificationEvent within 5 where TargetInstance ISA 'Win32_Service' and TargetInstance.Name='MSSQLSERVER' and TargetInstance.State='Stopped‘”

THE BEAUTY OF WQL

• WQL for WMI/WMI SQL

• WQL For Event Query
