Servermeister.com server monitor is a cloud based monitoring service and hence cannot be installed as an application in your servers.
Linux server monitoring is possible only using Servermeister.com Linux agent that can be downloaded and installed in your servers/desktops. Using Linux commands, the agent will gather server metrics such as CPU usage, memory usage, disk usage, processes, and network statistics every 5 minutes and push it to the Servermeister.com central server. You can access this performance data by logging into your Servermeister.com account on a web browser.
However, if you wish to install the application behind your firewall, we would recommend you to check out Applications Manager that would offer you the on-premise version of Servermeister.com.
