Tests The Accessibility of WMI Counters

WMI stands for "Windows Management Instrumentation" and is the technology from Microsoft for monitoring and management of Windows based systems.

WMI works like a database and offers a variety of useful monitoring values of Computers running Microsoft Windows. Products like Paessler's PRTG Network Monitor make use of the WMI functionality to monitor computers in network environments. WMI allows a process to read out data for many Windows' configuration parameters as well as current system status values. Access can take place locally or remotely via a network connection. WMI is based on COM and DCOM and is integrated in Windows 2000, XP, 2003, Vista and later.

As WMI access over a network is not quite trivial, the Paessler WMI Tester is a tool for testing the accessibility of WMI in a quick and easy-to-use way.

Note: If you run into problems while accessing a remote PC via WMI, please review our Guide to Troubleshooting WMI Problems.

 

Basic Usage

After starting Paessler WMI Tester you can enter the following data:

 

  • Domain: the Windows domain in which the computer you want to test is in. Leave empty when testing your own machine or a domainless machine (i.e. a standalone computer or a computer in a workgroup).
  • Host: the name of the computer you want to test. Leave empty when testing your own machine.
  • User: the name of the user that is allowed to log in on the machine you want to test. You MUST leave this empty when testing your own machine.
  • Password: the password of the user. You MUST leave this empty when testing your own machine.


Now click the “Test!” button. After a short time you will either see a result table showing information about the Windows system on the machine or an error message if something went wrong.

 

Advanced Usage

On this tab you can enter:

  • Domain prefix: will be added internally to the Host name (usually you can leave this at NTLMDOMAIN)
  • Namespace: the name space the WMI query will use, standard is root\CIMV2
  • Query: choose between six predefined query sets (operating system, processes, logical disks, memory, processor, network) or enter your own query (if you know how WMI works!)
