Scout Realtime streams disk, memory, network, CPU, and process metrics over the Internet. Only authenticated users can access the data. The app was coded in Ruby and is meant for webmasters that need to watch how their servers behave in a production environment. Excellent for troubleshooting, the app can also be used in test environments to discover buggy apps and research their issues further. Scout Realtime is easy to install, can run on any port, and needs a SSH tunnel to work securely.
