If you just comment out the host and related service from the config, does that solve your woes?

#define host{
#use windows-server ; Inherit default values from a template
#host_name winserver ; The name we're giving to this host
#alias My Windows Server ; A longer name associated with the host
#address xxx.xxx.xxx.xxx ; IP address of the host
#}



define hostgroup{
hostgroup_name windows-servers ; The name of the hostgroup
alias Windows Servers ; Long name of the group
}

#define service{
#use generic-service
#host_name winserver
#service_description NSClient++ Version
#check_command check_nt!CLIENTVERSION
#}

Negative, if I comment out anything INSIDE the windows.cfg file, nagios service fails to start:

administrator@Nagios:~$ sudo /usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg

Check your configuration file(s) to ensure that they contain valid

Likewise, if I comment out the entry for the windows.cfg INSIDE of the nagios.cfg file, it does the same.

Could you run the following and post the output?

Code: Select all

cd /usr/local/nagios/etc
grep -R -i winserver *

administrator@Nagios:/usr/local/nagios/etc$ sudo grep -R -i winserver *

Stop the nagios process by running the following

Code: Select all

service nagios stop
killall nagios

Edit the nagios.cfg file and comment out or delete the following line

Code: Select all

 cfg_file=/usr/local/nagios/etc/objects/windows.cfg

Run the check

Code: Select all

/usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg

If it is error free, start the nagios process

Code: Select all

service nagios start

So it looks like the hostgroup windows-servers is defined in your windows.cfg?

This file (/usr/local/nagios/etc/objects/xxxxxxxx.cfg) has a host that is referencing the windows-server hostgroup, that hostgroup needs to be defined somewhere (like /usr/local/nagios/etc/objects/hostgroups.cfg).

Make sure that it's included in your nagios.cfg

Code: Select all

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