I am getting the error:

ERROR: rpmforge-release RPM was not installed - exiting.

centos is not my distro of choice so this might be a stupid issue.

Thanks for the Help.

CentOS changed some URLs. Please, first install RPMforge following the
directions on this Web page:
http://wiki.centos.org/AdditionalResour ... s/RPMForge

Run in terminal:
# yum update

Proceed with the Nagios Xi install as described in our documentation.
