2、 Interface) is a set of extensions to the Windows Driver Model that provides an operating system interface through which instrumented components provide information and notification. WMI is Microsoft's implementation

5、8.</p><p>　　1 Purpose of WMI</p><p>　　The purpose of WMI is to define a non-proprietary set of environment-independent specifications which allow management information to be shared between mana

6、gement applications. WMI prescribes enterprise management standards and related technologies that work with existing management standards, such as Desktop Management Interface (DMI) and SNMP. WMI complements these other

10、 standards with some specific extensions that represent the various Windows components. Moreover, WMI exposes a collection of </p><p>　　COM-scriptable objects that allow various applications to take advantag

11、e of the management information.</p><p>　　As part of the installation process, most of the Microsoft applications available today (e.g. SQL Server, Exchange Server, Microsoft Office, Internet Explorer, Host

12、Integration Server, Automated Deployment Services) extend the standard CIM object model to add the representation of their manageable entities in the CIM repository. This representation is called a WMI class, and it expo

18、;　　Step 3 – Test the provider</p><p>　　Step 4 – Create consumer sample code</p><p>　　4 Importance of WMI providers</p><p>　　Since the release of the first WMI implementation during

19、the Windows NT 4.0 SP4 era (as an out-of-band download), Microsoft has consistently added WMI providers to Windows. Under Windows NT 4.0, Microsoft had roughly 15 WMI providers available once WMI was installed. When Wind

20、ows 2000 was released, there were 29 WMI providers as part of the operating system installation. With the release of Windows Server 2003, Microsoft included in the platform more than 80 WMI providers. Windows Vista inclu

21、des</p><p>　　During these last years, due to a constant increasing exposure of management data through WMI in Windows, more and more people in the IT systems management field started to develop scripts and a

22、utomation procedures based on WMI. Beyond the scripting needs, most leading management software in the world, such as MOM, SMS, ADS, HP OpenView for Windows (HPOV), BMC Software or CA, Inc. are WMI-enabled and capable to

23、 consume and provide WMI information through various User Interfaces. This enables adm</p><p>　　5 Features</p><p>　　For someone willing to develop one or many WMI providers, WMI offers many feat

24、ures out of the box. Here are the most important advantages:</p><p>　　(1) Automation interfaces: Because WMI comes with a set of automation interfaces ready to use, all management features supported by a WMI

25、 provider and its set of classes get the scripting support for free out-of-the box. Beyond the WMI class design and the provider development, the Microsoft development and test teams are not required to create, validate

26、and test a scripting model as it is already available from WMI.</p><p>　　(2) .NET Management interfaces:Because the System.Management namespace [6] relies on the existing COM/DCOM plumbing, the created WMI p

27、rovider and its set of WMI classes becomes automatically available to all .NET applications independently of the language used (e.g. C#, VB.NET). Beyond the WMI class design and the provider development, like for scripti

28、ng, the Microsoft development and test teams are not required to create, validate and test new assemblies to support a new namespace in the .NET F</p><p>　　(3) C/C++ COM/DCOM programming interfaces:Like most

29、 components in Windows, COM/DCOM programmers can leverage the features of the provider they develop at the COM/DCOM interfaces level. Like in previous environments (scripting and .NET Framework), a COM/DCOM consumer just

30、 needs to interact with the standard set of WMI COM interfaces to leverage the WMI provider capabilities and its set of supported WMI classes. To make all management information available from the native APIs, the WMI pr

32、rt will be available in Windows Server 2003 R2 through the WS-Management initiative lead by Microsoft, Intel, Sun Microsystems and Dell. This initiative allows to run any scripts remotely or to consume WMI data through a

33、 specific set of interfaces handling SOAP requests/responses. The advantage for the WMI prov</p><p>　　(5) Support for Queries:WMI offers support for WQL queries out of the box. This means that if a provider

34、is not designed to support queries, WMI supports it by using an enumeration technique out of the provider.</p><p>　　(6) Eventing capabilities:WMI offers the capability to notify a subscriber for any event it

35、 is interested in. WMI uses the WMI Query Language (WQL) to submit WQL event queries and defines the type of events to be returned. The eventing mechanism, with all related callbacks, is part of the WMI COM/DCOM and auto

36、mation interfaces. Anyone writing a WMI provider can have the benefit of this functionality at no cost for his customers. It will be up to the consumer to decide how it wants to consume the</p><p>　　(7) Code

37、 template generator:To speed up the process of writing a WMI provider including all COM/DCOM interfaces and related definitions, the WMI team developed the WMI ATL Wizard to generate the code template implementing a prov

41、r is a real gain as it increases the Return of Investment (ROI). A person facing such a situation simply expects things to work the sam</p><p>　　(9) Protect existing customer investments:Protecting customers

42、 and partners investment motivates customers to invest in technologies. As Microsoft did invest a lot these past years in writing WMI providers, customers and partners invested in tools leveraging the WMI capabilities of

43、 Windows. Therefore, they naturally continue to exploit these capabilities instead of having to use a new set of specific interfaces for each Windows manageable component. A specific set of interfaces means having a sp&l

44、t;/p><p>　　(10) Provide a logical and unified administration model:As briefly described before in the introduction, this model is based on an industry standard called CIM defined by the DMTF (http://www.dmtf.or

45、g). The CIM class-based schema is defined by a consortium of constructors and software developers that meets the requirements of the industry. This implies that not only Microsoft leverages the WMI capabilities, but also

46、 any other third party constructors or developers write their own code to fit int</p><p>　　6 WMI tools</p><p>　　Some WMI tools can also be useful during the design and development phases. These

47、tools are:</p><p>　　The MOF compiler (MOFComp.exe):The Managed Object Format (MOF) compiler parses a file containing Managed Object Format statements and adds the classes and class instances defined in the f
