Last month, I discussed EventMon.pl, a script that monitors events in logs on remote Win32 machines and displays those events in realtime. The magic behind this script is Windows Management Instrumentation (WMI). In my explanation of EventMon.pl, I mentioned that you ought to become familiar with WMI. This month, I insist on it.
Many of you are probably rolling your eyes right now and moaning about yet another Microsoft technology to learn. WMI is well worth learning because it offers a rich set of features that will meet most of your administrative needs. With WMI, your Perl scripts can query a machine's settings, processes, hardware, and more. These scripts can even monitor events that a remote machine fires.
To help you learn WMI, I explain how to access WMI from Perl. In addition, I provide a practical example of how you can use WMI with Perl. I don't focus on the nitty-gritty but rather give a cursory overview of the information you need to start using this technology. . . .
