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.

By default, the Nagios process needs at least one host check and one service check defined to run.
Usually there is a localhost.cfg file that is used to monitor the Nagios server. That file should be in somewhere in this folder or below.

Code: Select all

/etc/nagios3/

If you find it, copy them to this folder and see if the Nagios processes starts.

Code: Select all

/etc/nagios3/global

[jannetta]

The following files were in /etc/nagios3/conf.d
-rw-r--r-- 1 root root 1695 Jul 29 2011 contacts_nagios2.cfg
-rw-r--r-- 1 root root 418 Jul 29 2011 extinfo_nagios2.cfg
-rw-r--r-- 1 root root 1152 Jul 29 2011 generic-host_nagios2.cfg
-rw-r--r-- 1 root root 1803 Jul 29 2011 generic-service_nagios2.cfg
-rw-r--r-- 1 root root 678 Jul 29 2011 hostgroups_nagios2.cfg
-rw-r--r-- 1 root root 2167 Jul 29 2011 localhost_nagios2.cfg
-rw-r--r-- 1 root root 657 Jul 29 2011 services_nagios2.cfg
-rw-r--r-- 1 root root 1609 Jul 29 2011 timeperiods_nagios2.cfg

i copied localhost_nagios2.cfg you /etc/nagios3/global as localhost.cfg but it has not made a difference.

I also tried copying all files as is to the global directory, but it still didn't work.

What error are you getting when you run the verification?
Once those are resolved, then the Nagios daemon should start.

[jannetta]

All I can make of this is that localhost needs to be defined somewhere ... how? where?

Code: Select all

root@nagios:/etc/nagios3/global# systemctl start nagios3
Job for nagios3.service failed. See 'systemctl status nagios3.service' and 'journalctl -xn' for details.
root@nagios:/etc/nagios3/global# nagios3 -vv /etc/nagios3/nagios.cfg

In your nagios.cfg you have:

Code: Select all

cfg_dir=/etc/nagios3/global
cfg_dir=/etc/nagios3/Default_collector

In one of these directories you should have some .cfg files.

Have a look at these example files which may be what you need to get it to work:
