WMI stands for "Windows Management Instrumentation" and is the technology from Microsoft for monitoring and management of Windows based systems.
If you run into problems while accessing a remote PC via WMI, please review our guide to troubleshooting WMI issues.
WMI works like a database and offers a variety of useful monitoring values of computers running Microsoft Windows. Paessler PRTG makes use of WMI functionality to monitor systems in network environments. WMI allows a process to read data for many Windows configuration parameters and current system status values, locally or remotely. It was built based on COM technology and has been integrated into Windows since Windows Server 2000.
Because WMI access over a network is not trivial, the Paessler WMI Tester lets you quickly test the accessibility of WMI counters. You can test the WMI connection on your local system or on a remote target system. Remote access to WMI was traditionally handled via the DCOM protocol. The current recommended protocol is Windows Services Management (WSMan). PRTG and the WMI Tester support both protocols.
You can use the WMI Tester to test the WMI connection of a target system or your local system. Enter the login credentials, such as the domain, IP address, and user credentials, of the system that you want to test and specify if the WMI Tester should use WSMan or DCOM. If you want to test your local system, leave all the fields empty and just click Test! to start.
The WMI Tester returns a result table with system information or an error message. You can save results in a .csv file.
For more custom queries, the WMI Tester offers advanced options. You can further specify a domain prefix and a namespace for the WMI query. If you experience issues with results, you can also change the calculation base.
There are six predefined query sets available: OS, Processes, Logical Disks, Memory, Processor, or Network. And if none of these cover what you want, you have the option to use custom queries.
