The installation is straightforward. However, there is a dependency on the application layer that requires a restart of the application. It's a service, not the server, but a restart of the service is required. It is the same case with any other application.

The initial setup is very easy. It's not complex at all.

There are two servers in diagnostics. One of them is the Commander. Commander is our UI. And agents connect data and send it to the Commander. Between Commander and the agent, there is a Mediator server. One of our projects is developed by .net and the other platform is Java. .net agents collect data and Java agents collect data, and Mediator. Mediators send all of the data to Commander. If we have to install a new server, with just agents, it takes about two hours. 

Setup in Micro Focus depends on which application and which tool you are using. It also depends on the skills of the person who is handling it and if they are capable. I have not had much difficulty with setup.
