We have Nagios Core 3.2.1 installed and my current task is to allow non-admin users access to the Nagios UI. Is that even possible? or would i need to install some add-on?

Is it possible to create “view only” users?

Sure, you can do it by using the authorized_for_read_only variable:

/usr/local/nagios/etc/cgi.cfg

# A comma-delimited list of usernames that have read-only rights in
# the CGIs. This will block any service or host commands normally shown
# on the extinfo CGI pages. It will also block comments from being shown
# to read-only users.

authorized_for_read_only=anonymous

and let them view only specific services/servers?

Create a contact definition with the same contact_name:

/usr/local/nagios/etc/objects/contacts.cfg

define contact{
        contact_name                    anonymous
        use                             generic-contact
        alias                           No Name
        service_notifications_enabled   1
        host_notifications_enabled      1
        service_notification_period     24x7
        host_notification_period        24x7
        service_notification_options    c,w,r
        host_notification_options       d,u,r
        email                           [email protected]
        }

(that's called a authenticated contact)

then make him is the contact of the hosts/services which you want to allow to view:

define host{
        use                     linux-server
        host_name               localhost
        address                 127.0.0.1
        contacts                anonymous
        contact_groups          admin
        }

yes, Simply create a user without any special privs.

Well I have tried changing the authorized_for_read_only property as well. but in order to view the services and hosts following configuration changes needed to be done as well. After that restart the apache server.

authorized_for_all_services=nagiosadmin,--your user--
authorized_for_all_hosts=nagiosadmin,--your user--
