Better Nagios UI? [closed]
Take a look at Ninja,
The Ninja project is an effort to develop an alternative Nagios gui with the aim of being the most useful Open Source web front end for Nagios.
It's currently a litte tricky to get running, but worth it and looks great. Hopefully it'll become default GUI for Nagios someday.
With the limited dev work going in to the free version of Nagios the community fork Icinga looks very interesting. There have a new Web UI with more features and a cleaner look as well. There are some screenshots on this page https://www.icinga.org/screenshots/new-web/
