I like the way it summarizes all the services and the servers in a convinient dashboard and the fact that you can monitor services within servers and and servers within hosts. The services status pane is easy to read and to the point and also the licensing count. Its a really great tool that has survived during years as a must have tool for any system admin.

The setup of this tool has remained on the tedious side over the years (ubuntu server setup) having to follow long step by step instructions to put it to work to full potential - compared to other easy to set up monitoring tools like ITMANAGER.net, it falls behind in the setup area - although the user graphical interface has been improving during the years.
