Dont expect any bells and whistles, or really any usability for that matter. The technology is rudimentary at best, but it can get the job done with the right skills on staff. Many vendors have introduced products which make Nagios more usable, these improve the product itself, the supportability, and the fact that you can get support when things break. The problem is that the underpinning and ugliness still exist once you get through the layers intended to cover up the mess that Nagios is. There are still scripted checks which run to determine service health, the checks are normally challenging to manage, especially when some execute through the agent, while others do not. Other features added include better management, dash boarding, and other basic capabilities that you would expect out of the box with any monitoring product. The problem with all of these approaches is that they dont auto configure themselves, they dont detect application instances properly or consistently, and configuration of checks is painful.
