I'm installing nagios on SLES 12, using zypper nagios, but seems that some parts are not installed, ex: nagios-www, configuration file like /etc/nagios/nagios.cfg or /etc/apache2/conf.d/nagios.conf

The packagis and files are available in SLES 11, but not on SLES 12?
I've looked for documentation for SLES 12, but without success.

Can I have any suggestion?

Thanks, Fabrizio
