With this config did you restart httpd?

And if so can you repost the error_log when accessing after updating to this config?

Thanks

yes, the config you posted and http restarted.


Here are the entries in error.log with apache in debug mode when I click the "Submit Check Data" button.

Are you getting no response on the front end still? Or a 500 error?

Also, can you show the output of and

Where is your nrdp.conf ?
What OS and version is this?
We may need to try to re-create your setup

/usr/local/nagios/etc/nrpd.cfg

Ubuntu 17.04
root@myserver:/usr/local/nagios/etc# uname -a
Linux myserver 4.4.0-96-generic #119-Ubuntu SMP Tue Sep 12 14:59:54 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux

Ok, here's a problem, your nrpd.cfg needs to go in a directory that is going to get picked up by apache.

I think on your system it needs to go in /etc/apache2/conf-enabled/

Then restart apache2

Sorry, that's my mistake. I got that config file confused with the nrpe.cfg.

The nrdp.conf file is already located in /etc/apache2/sites-enabled/

I just went through setting this up and also was getting a 500 error until I installed this package
