Nagios Support Forum

Hi all,

I'm a complete linux and nagios virgin so please be gentle..

I have setup a Ubuntu (12.04) server in a VM and installed nagios (4.3.1) + pluging (x.1.16) as described in the articles on the Nagios website for the core install and plugin.

As far as I can tell there were no errors during any of the install processes.

When i go the web site the localhost is showing as down and critical on all services.

Looking for some help on what i can check to ensure my installation is working correctly?

Thanks,
Mark

You can check the configuration files with the following:
Are you behind a proxy? Are you using a VPN Tunnel? Have you tried turning off the operating system's firewall to test?

Did you install Nagios from source, and finally what type of checks are you attempting to create that are going critical?

Hi, I have the exact same issue.
/usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg came back clean.
There were some errors when running step # 6 of the quickguide (http://nagios.sourceforge.net/docs/nagi ... buntu.html)
'Make' and 'make install' gave an output like;

make[2]: *** [check_http.o] Error 1
make[2]:Leaving Directory ....
make[1]: *** [all_recursive] Error1

check_http.c:268:16: warning: ignoring return value of 'asprintf', declared with attribute warn_unused_result
make[1]: *** [check_http.o] Error 1
make[1]:Leaving Directory ....
make: *** [install-recursive] Error 1


Any ideas?

Regards,
Gary

If you are attempting to follow documentation for Nagios Core that is supplied by Nagios Enterprises directories may differ than those of the Ubuntu guide as they have a customized version of Nagios. We recently released an install guide for installing from source on Ubuntu which can be found here:

Have you checked what was posted above? Proxy, VPN, etc?

Thanks for your help. I used this install guide and I am now up and running.

Excellent glad it worked out for you.
