Trying Nagios for the First Time

[Seth Hollist]

Ok, I tried your suggestions and got some strange results.  Here's what I
did:

----------------

# nagios

Nagios 1.1
Copyright (c) 1999-2003 Ethan Galstad (nagios at nagios.org)
Last Modified: 06-02-2003
License: GPL

Usage: nagios [option] <main_config_file>

Options:

  -v   Reads all data in the configuration files and performs a basic
       verification/sanity check.  Always make sure you verify your
       config data before (re)starting Nagios.

  -s   Shows projected/recommended service check scheduling information
       based on the current data in the configuration files.

  -c   When used in conjunction with the -s option, this option will cause
       the status data to be updated with scheduling information.  It is
       not recommended that you use this option while Nagios is running, as
       the information in the status log will be temporarily overwritten.
       Provided as an aid to help you understand initial check scheduling.

  -d   Starts Nagios in daemon mode (instead of as a foreground process).
       This is the recommended way of starting Nagios for normal operation.

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

Nagios 1.1

Reading configuration data...

Error in configuration file '/etc/nagios/nagios.cfg' - Line 45 (NULL
variable)

***> One or more problems was encountered while processing the config
files...

-----------

So I looked at my nagios.cfg file and found the following:

42> # You can split other types of object definitions across several
43> # config files if you wish (as done here), or keep them all in a
44> # single config file.
45>
46> #cfg_file=/etc/nagios/contactgroups.cfg
47> #cfg_file=/etc/nagios/contacts.cfg
48> #cfg_file=/etc/nagios/dependencies.cfg


As you can see line #45 is a blank line.  Why is it complaining about a
blank line?  I deleted the blank line, re-ran the command it came back
telling me "Thinks look okay".  I'm thinking that maybe the nagios.cfg file
from the original distribution has a tab or some other white space on that
line that's been giving me grief.

Thanks for your help.  I think I'm well on my way to getting this thing
setup and working, finally.

Try running it w/o the -d option and see if you get anything. Also check 
syslog and nagios.log for any error messages.
