I would like to keep an eye for performance and usage for a Windows 2012 R2 machine I have in AWS. The machine is visible (RDP) from the Internet, and I would like to be able to quickly see the Task Manager information (for example via a browser).
For example, to watch which users are connected (it is a Terminal Server), I was thinking on running quser and get the standard output posted by an specific ASPX page (this would imply that my machine security group opens port 80, of course). The ASPX page name would be password, because the page would be open to the Internet.
Which are my options to quickly get usage and performance data from the Task Manager without actually RDPing as Administrator to the machine in question?
