What is the error i this Nagios config file?

Nagios just installed, works fine. I added this line to my nagios.cfg;

cfg_file=/etc/nagios/objects/test-devs.cfg

Open in new window

Works fine if the test-devs.cfg is empty, I tossed this into the config file, what is wrong?

define host{
        use             linux-server            ;
        host_name       172.16.55.71            ;
        alias           Test Server 01          ;
        address         172.16.55.71            ;
        }

define hostgroup{
        hostgroup_name  linux-servers           ;
        alias           Linux Servers           ;
        }

define service{
        use                             172.16.55.71.services   ;
        host_name                       172.16.55.71            ;
        service_description             HTTP
        check_command                   check_http
        notifications_enabled           0
        }

I checked the existing config files, there is no linux-hosts actually defined anywhere and Nagios starts up fine, until I just add my own test host.

I get the error

Running configuration check... CONFIG ERROR! Restart aborted. Check your Nagios configuration.

Nagios log has not a single error listed.

;

at the end of most of the lines is probably where your issue is coming from

Ps instead of using
cfg_file=/etc/nagios/objects/test-devs.cfg

you can use
cfg_dir=/etc/nagios/hosts

then move the file test-devs.cfg from the objects directory to the hosts directory so that you can keep configuration objects and regular host / service defenition files seperated.

So, the items in the config file look correct?

Here is my /etc/nagios/nagios.cfg

# OBJECT CONFIGURATION FILE(S)
# These are the object configuration files in which you define hosts,
# host groups, contacts, contact groups, services, etc.
# You can split your object definitions across several config files
# if you wish (as shown below), or keep them all in a single config file.

# You can specify individual object config files as shown below:
cfg_file=/etc/nagios/objects/commands.cfg
cfg_file=/etc/nagios/objects/contacts.cfg
cfg_file=/etc/nagios/objects/timeperiods.cfg
cfg_file=/etc/nagios/objects/templates.cfg

# Definitions for monitoring the local (Linux) host
cfg_file=/etc/nagios/objects/localhost.cfg

# Definitions for monitoring a Windows machine
#cfg_file=/etc/nagios/objects/windows.cfg

# Definitions for monitoring a router/switch
#cfg_file=/etc/nagios/objects/switch.cfg

# Definitions for monitoring a network printer
#cfg_file=/etc/nagios/objects/printer.cfg

#cfg_file=/etc/nagios/objects/ups.cfg
cfg_file=/etc/nagios/objects/test-devs.cfg

So, I followed what I saw in localhost.cfg

Why would mine not work and localhost work? It would be helpful if Nagios actually entered an error into its logfile....

What error do you get when you run the nagios configuration validation as shown below?

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