Hi ,
Can any body help me out in the problem that i am facing regarding the installation of Nagios 3.0a4 on my Fedora Core 6 machine. The problem is that the important directory of /usr/local/etc/objects is not created, and i also didn’t get any errors during the installation of nagios on my machine. i need to make necessary changes to the files supposedly to be present in this directory. Any help in this regard is highly appreciated.
Thanks.

Hi
Same on my machine on Ubuntu.
I did:
apt-get install build-essential
apt-get install libgd2-xpm-dev
apt-get install apache2
apt-get install nagios-plugins
apt-get install nagios3
apt-get install nsca
I add new admin to user
and it’s working, i can see web on localhost/nagios3/ and can see monitoring localhost
But Objects folder and all files inside are missing i.e. windows.cfg etc.
When im trying to :
[code]root@tretos-desktop:/etc/nagios3# nagios3 stop

Can someone please tell me what im doing wrong and how to fix it ?
Did you install example config files?
maybe this is the problem?
i didnt cause i installed this like this:
apt-get install build-essential
apt-get install libgd2-xpm-dev
apt-get install apache2
apt-get install nagios-plugins
apt-get install nagios3
apt-get install nsca
It wasnt installed from source. You know how can i install those samples manually ? Fix this somehow ? I cannot get nagios to work with any other machine. Only Localhost.
You can download tar archive of nagios unpack it and then
./configure
make
This will create sample configurations files in sample-config/ directory. You can simple copy them into /usr/local/nagios/etc (only *cfg) and /usr/local/nagios/etc/objects dir.
Specify the problem
Cheers!
That what i got after i changed this line in nagios.cfg:
# Definitions for monitoring a Windows machine
cfg_file=/etc/nagios3/objects/windows.cfg
[code]:/etc/nagios3$ nagios3 -v nagios.cfg
Nagios 3.0.2

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.
tretos@tretos-desktop:/etc/nagios3$ ls
apache2.conf commands.cfg htpasswd.users nagios.cfg~ resource.cfg
cgi.cfg conf.d nagios.cfg objects stylesheets
tretos@tretos-desktop:/etc/nagios3$ [/code]
And thats the Resource.cfg

Nagios is running, i can login to webpage and see localhost monitored.
Now i just want to have windows monitored and it doesnt work…
I heard about nagios configurator, do you know which one is good ? You think this will help ?
eh… I will install this again from source. Not using apt-get.
Im running ubuntu on Virtual box so I can always go back…
I setup all nagios manually. I don’t trust any configurations 
And all I can say. check all paths and permissions twice because this was my problem number 1 in 99% of cases.
Or install nagios from source. You can always control all settings.
Good Luck!
Yes, thats what i did. And works fine
Do you how can I change the name of the host under: Hostgroup Overview
Now is taking name from Hostname, but i want to show the Alias.
Any idea how to change this ?
As far as I know there is a special attribute ‘display_name’ which can be set to custom host name, but this feature will be available in some of the next Nagios release
The only way is to change localhost name to the custom. in nagios.cfg there is a illegal_object_name_chars attribute where you can define which characters cant be used in host name.
Cheers!
