Microsoft System Center Operations Manager 2012 (OpsMgr) has the ability to monitor certain aspects of network routers and switches, firewalls, and other devices, making the service application a robust tool to actively identify potential network problems. Or, even better and more preferred, it allows you to verify that the infrastructure is humming along swimmingly.

Fortunately, Microsoft has put together an Excel spreadsheet of known devices that provide extended monitoring capability for OpsMgr 2012. Now, in its 3rd revision, the updated spreadsheet contains over 830 devices to sift through, providing a grocery list of your next infrastructure purchase, or a managed list to compare to what you already have installed.
Here's a sampling of what's included:
