I need to monitor some computers used by our retail staff. I only need to monitor these computers if a user is logged in. If a user is logged in I need to monitor a windows service that runs when they are using our banking software and possibly also monitor if the USB check scanner is properly detected by windows. I'd prefer to do this via the opsview agent since that is what I'm most familiar with, but i'm open to other suggestions. I'm thinking this is a good time to setup a dependency, but wanted to see what others' suggestions were.
