 Check your configuration file(s) to ensure that they contain valid
 directives and data defintions.  If you are upgrading from a previous
 version of Nagios, you should be aware that some variables/definitions
 may have been removed or modified in this version.  Make sure to read
 the HTML documentation regarding the config files, as well as the
 'Whats New' section to find out what has changed.

There is no hosts.cfg file in the etc of nagios.
How should it be created?

Thanks & Regards

When you ran
make all
you should pay attention to the other makes, you can run.
So, run it again, and read what it has to say after it has run
make all
there is a make that will install sample config files. Those are just examples.
You should then follow the nagios docs, and configure each and every item, like hosts, services, hostgroups, contacts, etc… These are not trivial, and nobody can make these for you. It’s up to you, to follow the docs, and define all these things.
Files you should have when done
/usr/local/nagios/etc/checkcommands.cfg
/usr/local/nagios/etc/misccommands.cfg
/usr/local/nagios/etc/contactgroups.cfg
/usr/local/nagios/etc/contacts.cfg
/usr/local/nagios/etc/dependencies.cfg
/usr/local/nagios/etc/escalations.cfg
/usr/local/nagios/etc/hostgroups.cfg
/usr/local/nagios/etc/servicegroups.cfg
/usr/local/nagios/etc/hosts.cfg
/usr/local/nagios/etc/services.cfg
/usr/local/nagios/etc/timeperiods.cfg
/usr/local/nagios/etc/hostextinfo.cfg
/usr/local/nagios/etc/serviceextinfo.cfg

If you choose to deviate from this, then we won’t be able the communicate with each other when troubleshooting.
Each of those files must be defined in the nagios.cfg file and where it is located. You can comment out some files like /usr/local/nagios/etc/escalations.cfg if you don’t want excalations.
