Hi ricardowesley,

You posted the below result;

root@plxnagios ~]# cat /usr/local/nagios/etc/nagios.cfg | grep cfg_file=
cfg_file=/usr/local/nagios/etc/objects/commands.cfg
cfg_file=/usr/local/nagios/etc/objects/contacts.cfg
cfg_file=/usr/local/nagios/etc/objects/timeperiods.cfg
cfg_file=/usr/local/nagios/etc/objects/templates.cfg
cfg_file=/usr/local/nagios/etc/objects/localhost.cfg
#cfg_file=/usr/local/nagios/etc/objects/windows.cfg
cfg_file=/usr/local/nagios/etc/objects/switch.cfg
#cfg_file=/usr/local/nagios/etc/objects/printer.cfg

I may be mistaken, bit it looks like you are missing the hosts.cfg and hostgroups.cfg defined in nagios.cfg?

Code: Select all

cfg_file=/usr/local/nagios/etc/objects/hosts.cfg
cfg_file=/usr/local/nagios/etc/objects/hostgroups.cfg

The names of you files may not be hosts.cfg and hostgroups.cfg, but just replace them with what you have.

For future, you also look to be missing services.cfg (where you define the services for the hosts in hosts.cfg).

Kind Regards,

Gary Shergill

I created a group allhosts in hostgroups.cfg located in /usr/local/nagios/etc/objects.
When I run /usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg prior this change... I receive this message
Warning: Duplicate definition found for hostgroup 'linux-servers' (config file '/usr/local/nagios/etc/objects/localhost.cfg', starting on line 46)
Error: Could not add object property in file '/usr/local/nagios/etc/objects/localhost.cfg' on line 47.
Error processing object config files!
Where and I how do I correct this problem?...It is preventing me from moving on.

I bet that the "linux-servers" hostgroup is not only defined in the localhost.cfg file, but also in the hostgroups.cfg file. Remove one of the declarations (probably from the localhost.cfg file) and try to verify once again.

Do you have the hostgroup 'linux-servers' defined multiple times in that configuration file? I'd start by taking the line it told you the issue was revolving around and figure out where and what you need to remove, after each change "such as removing a hostgroup definition" verify your configurations as you did above and eventually you will run out of errors to fix!
