Please provide better information in the "Un-used Modules" view.
"MON Service Monitor
The MON configuration file /etc/mon/mon.cf was not found on your system. Maybe MON is not installed, or your module configuration is incorrect."
I had no idea what MON is and why it would want it. So I did "yum search mon" on my Fedora 20 which states: "mon.x86_64 : General-purpose resource monitoring system" which seems to be important but is not installed on my dedicated server.
So how to install it?
Some Un-used Modules provide a call to "yum install" but in this case I have to install it on the console via ssh. Would be nice to have it in this case also.
