Can Activity Monitor connect to the computers through Internet?
Basically it can, but there are certain limitations. You need direct IP connection between computers, proxy servers are not supported. You should be able to ping the remote computer. Also it’s preferable that both computers have static IP addresses. You may install Agent remotely only if you know local Administrator password for that computer. Communications between Activity Monitor and Agents are encrypted using SSL for best security. It’s much easier if you have a VPN connection to your office. In that case you should be able to monitor computers at the office remotely or vise versa. If you want to monitor your office computers from home you can do this: Install Activity Monitor on one of the computers in your office network. Connect to that computer via Remote Desktop from home. Open Activity Monitor there. Then you can work with Activity Monitor as if you were sitting on that computer.
