If we take an instance where a business deals with manufacture and selling network interface cards (NICs), industry standards would be important. How can it be made easier for Ethernet NICs to work natively with systems based on Linux, OS X, and Windows?
Distributed Management Task Force (DMTF) comprises one way of making work for windows system administrators, based on their seamless work standards. It comprises the essence of this article and its significance to the Windows PowerShell-based systems administration.
Windows systems administrators rely on Distributed Management Task Force (DMTF) industry standards. DMTF is an industry consortium of major computer hardware and software manufacturers, who agree on standards so that their products can work and integrate as seamlessly as possible.
Relationship between CIM and WMI
Common Information Model (CIM) refers to computer software and hardware components. It is part of the larger Web-Based Enterprise Management (WBEM). All windows server or client computers have CIM repository. Microsoft wrote its own abstraction layer on top of CIM, named Windows Management Instrumentation (WMI), even though it is a DMTF member.
The most confusing for systems administrators is that in Windows PowerShell v3 and later, the CIM repository can be accessed through either CIM or WMI calls.
We shall basically find out what the pros and cons of each approach. The CIM repository in the example photo below helps to visualize the CIM repository.
WMI in Action
Much time should not be consumed here since Microsoft has depreciated them over their own CIM cmdlets. Most importantly is the WMI command for a computer running windows used in your environment.
Enumerated WMI cmdlets
To access the CIM repository of the local computer, Get-WmiObject works perfectly. The command defaults to the ROOT\CIMv2 namespace. The class name is all we need.
The WMI position starts showing when we use the -ComputerName parameter for WMI information revival from remote computers.
It works at a good cost since using WQL to query CIM repository data makes you feel at home. If the WMI cmdlets have an advantage, then taking action on CIM repository data from remote CIM repositories can do each connection request. The ability is good since the remote service can be controlled using dot notation
CIM in Action
While the old WMI cmdlets apply stateful connections for the trip over existing fire rules, and remote access, the CIM cmdlets are leaner as follows:
- The Get-CimInstance is the Get-WmiObject direct analog.
- CIM cmdlets support tab completion unlike WMI cmdlets
- An observation of both processes shows that they return similar results.
For remote cases:
- The PowerShell pipeline can be leveraged as follows
- YOU can call StopService
For many areas where this technology is used, it is important to understand how it works and what improvement; mastering PowerShell-based management with CIM and using CIM sessions for more efficient use of network bandwidth when managing remote computers is important in the manufacturing and retailing networks such as fast moving consumer products, automobile manufacture and sales , clothing industry etc.
