Puppet dashboard with puppetmaster based on Centos 7

Hi all, Is there someone using Puppet dashboard with a puppet master based on Centos 7 ? I tried but could not get rid of dependencies with ruby... Also if you got some alternatives solution for dashboard/monitoring, easy to configure and install, you are welcome :) Thanks for the helps buddies. Some info : My current configuration :
