Monitor All Processes

I'm an Orion NPM and APM newbie, so bear with me.  I appreciate any help you are able to provide.

 

I have a user interested in monitoring all processes currently running on a server.  In other words, he wants to be able to see all the processes that are running at that period of time - not just a process that has already been configured in APM.  I know this may involve WMI scripting, but I'm afraid I have very little experience in this area. 

Is anyone aware of a way to monitor all running processes in APM?  Thanks.
