Cons

"We use the free version of Nagios, which needs some administrative skills in order to configure correctly."
"Nagios Core is limited in terms of distributed setups, and there is no central view for remote data centers."
"The UI is a little outdated and graphics could be displayed in a better way."
"Generally, it does what I need it to do, but better error reporting would be great."
"Nagios' great customizability is also one of its greatest drawback."
