In version 5 of Kaseya Network Monitor, we have implemented a new Lua library, making it possible to run Powershell scripts or other command line utilities on a Windows host and present the result in KNM.
We have created a Lua script that utilizes this new library as an example, fully usable right now. For more information, read the article at http://community.kaseya.com/resources/m/knowexch/86375.aspx to download the script. It will be included in the next build of KNM.
