**Edit**
To expand on what I asked, by default you will get 403 forbidden when running check_http against localhost in a CentOS box because directory listing is forbidden and you have no index file. If you create the file it will change the behavior of the system. It's a common occurrence that a base install of Nagios on base CentOS will have the problem you described if there is no index file in /var/www/html.
Yes, apparently that fix the issue:
Code: Select all
# /usr/local/nagios/libexec/check_http -H localhost
HTTP OK: HTTP/1.1 200 OK - 265 bytes in 0.001 second response time |time=0.001032s;;;0.000000 size=265B;;;0
Although I am still seeing CRITICAL on the service checking at Nagios Web interface:

Did you per-chance change your commands.cfg or your service in order to resolve the issue using other methods, and perhaps something needs to be changed back?

Something weird for sure.
Please send a tail of your /var/log/httpd/access_log and also /var/log/httpd/error_log.

Let's run this as the nagios user, and with some extras thrown in:
Code: Select all
su nagios
/usr/local/nagios/libexec/check_http -H localhost -vvv > /tmp/check_http.txt
echo $?
Then send us
/tmp/check_http.txt and show us the output of the command.
