Introducing PoshEventUI: A UI Way to Create Permanent WMI Events

Something that I have been working on the past couple of months (in between other things) was a UI approach to creating permanent WMI events vs. a command line approach.

I really had only a few requirements that I wanted to achieve with this:

  • Have a main window showing the current WMI events
  • Have Add/Remove buttons for each instance (Filter,Consumer and Binding)
  • Use separate windows for each instance
    • The Consumer window will have one window but will change based on the type of Consumer being created

So without further ado, here is my latest project: PoshEventUI


The main UI window is based on Trevor Sullivan’s wmieventhelper.exe available from http:s//

The download for this is at

Once you download it, unblock the file so PowerShell will not complain about it and prompt for each script being run (Unblock-File works great!)


Navigate through the unzipped folder and run .\wmieventutility.ps1


Once the window has been opened, you can choose to to create a New instance or to Remove and instance.


Let’s work through each of these just to get an idea on what you can do.

First off is the Filter.


Here you can specify a Name and a WQL Query that will be used to monitor for a specific event in WMI. You can look at my articles on Temporary Events and Permanent Events for ideas or look at some searches on your favorite search engine. Also available is some great information in the PowerEvents documentation that shows more on working with WQL queries and also provides some great examples.


Once completed, click Create and it will now be added to the WMI repository.


Next up is the Consumer creation. There are 5 possible consumers to choose from and you can have multiple consumers setup with a filter via the Binding, so use whatever you wish to accomplish your requirement.

Lets look at all of the possible Consumer choices. You can pick whichever consumer you prefer from the drop down menu in the upper left hand corner labeled Select Consumer Type.












In this case I am going with an SMTP consumer.


Note that with the From field blank, it will default to WMI@<computername>.com for the address.

Once you have the picked out your consumer and entered the necessary information, click Create and you will be taken back to the main window with the new consumer listed.


You can event filter the Consumers based on the type using the drop-down menu.


Last on the list is to bind these together using the Binding.


Not really a lot to it. You pick the Filter and Consumer and click Create. This will create the binding and enable the WMI event subscription.


That is really all there is to it! The trick is really knowing the WQL query for the Filter and then determining what kind of consumer fits this best.

Almost forgot… You can even connect to remote systems to add and remove event subscriptions! Just click on the File menu and select Connect to Another Computer.


Enter a computername and click OK and away you go.



Please keep this mind that it is in Beta, so there will most likely be bugs crawling around. Just stop by the Issues page and let me know what they are and I will work to get rid of them. I do have plans for a Template feature which will have pre-determined Filters as well as the option to save custom filters as templates for use later. This may also move over to the Consumers as well at a later date.

Hope everyone enjoys this!

    Yeah, i think this idea very interesting for a new version. I will see this article for try create a consumer for multiples systems.

    Hi Boe Prox this project really helped me, but now i need create a permanent event to notify sql services to 70 servers, the issue is, i need create one by one or there a way for create to all servers together?
