The framework for management information and activities on Windows-based operating systems is called Windows Management Instrumentation (WMI).
What is Windows Management Instrumentation (WMI?)
What is the purpose of WMI?
WMI also enables you to monitor system events and collect performance data.
This data can be used to troubleshoot problems or to track trends over time.
Everything from monitoring system performance to acquiring utility data is possible with it.
The Distributed Management Task Force (DMTF) creates and maintains CIM.
It allows programmers to construct management programs that work with any system that supports WMI.
Lets see the architecture and terminology of WMI.
WMI infrastructure receives data from an object through a provider.
It provides and receives messages from WMI and hands them over to the object.
WMI categorizes providers according to the functionality provided by the providers interface.
TheWMI infrastructureis a component of the Microsoft Windows operating system known as the WMI service (winmgmt).
The WMI Core and the WMI Repository are the two parts of the WMI infrastructure.
Other WMI namespaces may be created by additional WMI providers, and each namespace contains several WMI objects.
TheWMI serviceacts as an intermediary between the providers, management applications, and the WMI repository.
Only static data about objects is stored in the repository, such as the classes defined by providers.
WMI obtains most data dynamically from the provider when a client requests it.
AWMI consumeris a management program or script that communicates with the WMI infrastructure.
WMI creates a standardized interface for remotely and locally retrieving management data.
The uniform interface abstracts from the operating systems app programming interfaces (APIs).
This allows apps and scripts to collect management data without needing to know about the operating system API.
How to run a WMI query?
It is easier than an asynchronous call because it only takes one interface call.
For large searches or web connection-based inquiries, it may, however, freeze up your system.
They both have a similar syntax structure.
Select,From, andWhereare the fundamental WQL statements that are utilized to launch the query.
A typical WMI query starts by selecting all the properties from a WMI class using the Select command.
The asterisk (*) is used to select every property from a WMI class.
You may check theSQL cheatsheetfor the exact syntax.
WMI queries also can be executed through Windows PowerShell, VBScript, and C language.
throw in of WQL Queries
The WQL queries are utilized to get three different types of information.
Object Queries:Information about Windows system resources can be retrieved using these queries.
Schema Queries:These queries are used to obtain details about the structure of the WMI schema.
Running a Query
Lets see how to run an object query.
The following method states how to check WIN_32 processes on a local system.
The tool WMI Tester is executed through the command line by entering wbemtest.exe.
The following window will pop up.
To run this query in VBScript and C language, theMicrosoft documentation pagewould provide complete insights.
