Nagios Support Forum

New to nagios not sure if I can add a host through the webmin or do I have to do it at command line?

I am new to nagios step by step please.

You would need access to a Nagios Core, or Nagios XI system to add a new host, you cannot do this from Nagios Fusion.

Which one is free? the admin who left added hosts and he used this box.
Also how is this done? vi remotehosts.cfg? where is the file located I'm using open suse 12.3 and it isn't in Does anyone know where remotehosts.cfg is in nagios on opensuse 12.3?
these are the files I have in my /etc/nagios directory "cgi.cfg htpasswd.users nagios.cfg nagios.cfg_2014-01-04-12:01 objects resource.cfg"

remotehosts.cfg isn't in this directory.

There has to be a way because the Server is functioning fully monitoring all the host he added. green up and red Down.


Yes it is nagios core 3.5.0

Okay, so this is not Fusion, I am going to move this to the General Core Support section... I'd recommend taking a look at this documentation:

http://nagios.sourceforge.net/docs/3_0/toc.html

Take a look at the "How To monitor ___" section.

I found config files here /etc/nagios/objects


see one example below

define host{
use windows-server
host_name ahgserver2003
alias ahgserver2003
address 10.1.0.10

do i just vi a file ie "vi nasserver.cfg" and paste in this template. modify parameters for my new host and save? or is there more to it?

Then restart nagios service? What command do I use to do that?

" service nagios restart" - Should restart nagios and attempt to use the new configs. Also I would note that you should never use webmin to administer a nagios box. It will severely mess up the permissions on files and folders.
