Check the Configuration tab in nagios web interface, there it shows the "live" config aka. what it read and loaded. You probably need to add the new config to your nagios.cfg file, so Nagios can read it. You also have a parameter in nagios.cfg, that you can set to a folder, and it reads all *.cfg files in that folder, thaat way you dont need to specify all config files seperatly. <div class="gmail_quote">On Fri, Jul 24, 2009 at 11:52 AM, Dayo Adewunmi <<a href="mailto:contactdayo@gmail.com">contactdayo@gmail.com</a>> wrote: <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> Hi all I copied localhost.cfg to create an object definition for a new host: <a href="http://pastebin.com/f21c9df1c" target="_blank">http://pastebin.com/f21c9df1c</a> No matter how often I restart nagios, the new host isn't being monitored.
