Please pardon the gratuitous noise, but JC's yum repo has saved me at least a couple of man days in building a Xymon monitor on Centos 7 for a nonprofit that I now support pro bono, so I want to shout out.
I was a Big Brother-->Hobbit-->Xymon practitioner from roughly the beginning before retiring a year and a half ago. I do Fedora (and Xymon) at home, and was a bit out of touch with Red Hat and Centos. Japheth's repo let me get the basic stuff up and running in an hour, and I'm off to the races (took a couple of hours to do the Centos 7 netinstall because it wouldn't DHCP). JC's repo is all the more remarkable given that RPMFusion is as yet still unable to support Centos 7.
I do still need to work through monitoring, as best I can, an entirely non-Linux setup. XBlue VOIP phones, Ubiquiti wifi APs, Windows 2008 R2 server with SQL Server, Windows shares over a 3 point VPN.
Also, large thanks to Sean and Henrik.
Regards to all,
Jake
