Problem Description

When you attempt to install or upgrade Nagios XI you receive the following error:

"ERROR: Please add the 'Optional' channel to your Red Hat systems subscriptions

 

Resolving The Problem

Red Hat Subscription Manager:

You need to add the Optional software channel so that Nagios XI can install the necessary prerequisites using one of the commands below (depending on your version of RHEL):

RHEL 6.x

yum install -y yum-utils
yum-config-manager --enable rhel-6-server-optional-rpms

 

RHEL 7.x

yum install -y yum-utils
yum-config-manager --enable rhel-7-server-optional-rpms

 

Red Hat Network Classic

You need to add the Optional software channel so that Nagios XI can install the necessary prerequisites.

To do so, first sign in to your Red Hat Network account at http://rhn.redhat.com/.

Then click on the link corresponding to your system.

Near the bottom-left corner of the page, click Alter Channel Subscriptions.

Check the box labeled RHEL Server Optional and click Change Subscriptions.

 

That's it! You should be able to run the installer again and complete your installation.
