OMD Server Installation
For more information on Open Monitor Distribution, visit omdistro.org
Description:
OMD bundles Nagios together with many important addons and can easily be installed on every major Linux distribution. We provide prebuilt packages for all enterprise Linux distributions and also for some other, such as Ubuntu.
OMD currently comes with the following software:
Nagios Monitoring Plugins (Former known as Nagios-Plugins) nsca, check_nrpe, Icinga, Shinken, NagVis, pnp4nagios, rrdtool/rrdcached Check_MK, MK Livestatus, Multisite, Dokuwiki, Thruk, Mod-Gearman check_logfiles, check_oracle_health, check_mysql_health, jmx4perl check_webinject, check_multi
Pre-Requisites:
Install the packages that are needed to support OMD
These instructions are only compatible with Debian
and Ubuntu 
Although OMD can be installed on CentOS 7/RHEL 7, the site does not come up clean, and extensive troubleshooting is required to compile non RPM bundled dependancies such as mod_python.
