Powershell script to remotely monitor a Server Process

Here is a simple Powershell script, which will show a Message box, if a process on a remote machine is taking too much memory.

To run the script:

• install PowerShell 2.0
• then from the command line:

powershell -F monitor_build_mc.ps1


You can make a batch file which contains the above line, and then run this from a Windows Scheduled Task, to automatically alert you, when a process (like a Web Server) starts hogging the server machine.
