Did you by accident disable the notifications? On the Nagios web interface, click on Tactical Overview. At the end of the page (Monitoring Features) check that Notifications are green/enabled. It would make sense as you don't have SELinux and all commands seem to work from command-line (you also checked them with your Nagios user, not root, right?). <div class="gmail_quote">On Fri, Dec 2, 2011 at 11:30 AM, Nick Price <<a href="mailto:np121@hotmail.com">np121@hotmail.com</a>> wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;"> <div link="blue" vlink="purple" lang="EN-US"><div>Ok I am getting in the debug log Notification viability test failed.

What is your notification config? can you run the commands the notification uses as the Nagios user? Is there some security such as SE Linux running? You could try adding logging to the Notification command eg add a ">> /var/tmp/Notification.log" or instead of the Notification command being a direct command, make a script for it instead.

I have a clean install of fedora 16 32 bit with a manual install of nagios 3.3.1 and nagios plugins 1.4.15. I see in the debug log Notification viability test failed. No notification will be sent out. I can send test emails from this server using sendmail and that bit works Is there a solution for this.
