Nagios Support Forum

Trial version of Nagios XI Enterprise edition. Downloaded VMWare image, patched and updated, configured for our environment.

Everything is working well except for emailing pdf or jpg reports. Email notifications work perfectly and reports sent as csv work fine as well. The web interface becomes unresponsive when attempting to email reports either as jpg or pdf. SSH is still active, service nagios restart and service nagiosxi restart do not help. Server needs to be restarted to re-enable web interface.

Are you forcing SSL? I noticed the 443 in your paste from the profile page.

Additionally, please attach a screenshot of your Admin -> System Settings page, and also your /etc/hosts file for us to take a look at.

Yes, we are forcing SSL. ipv6 is disabled too. Reports sent as csv work perfectly. The web interface hangs when sending as pdf or jpg.

/etc/hosts
127.0.0.1 localhost.localdomain localhost.localdomain localhost4 localhost4.localdomain4 localhost
::1 localhost.localdomain localhost.localdomain localhost6 localhost6.localdomain6 localhost

It may not be resolving internal calls properly.

Can you also attach a screenshot of your Admin -> System Settings page?

Thanks for the /etc/hosts listing, but we have to see a screenshot of the Admin -> System Settings page as well --

Please validate that under Admin > System Settings that your Program URL and if you're using the External URL are accessible from the XI command line (can XI ping it from the command line).

Since you are forcing SSL, did you edit:
And set:
Also, is there a proxy in front of this?

I always add the FQDN on the 127.0.0.1 /etc/hosts entry so that it would never go out of the server for local requests.

In the XI gui, can you go to Admin > System Settings and make sure the External URL is valid?
Also, can you run the following command while logged in as root to the XI server. Then try and email a report and post the output from the tail command.

Under Admin > System Settings I verified that the program url was using https.

I did not have the following set so I edited /usr/local/nagiosxi/html/config.inc.php and set $cfg['use_https'] = true;

I added the fqdn to the hosts file, tailed /var/log/httpd/error_log while trying to send reports with pdf and jpg attachments and was able to successfully send pdf and jpg attachments.

I believe the piece that resolved this was adding the fqdn to the hosts file. I see in the error_log that prior to adding the fqdn the server was being resolved to it's external address and I was getting a zend_mm_heap corrupted error in the logs, once the server was able to resolve the fqdn to 127.0.0.1 everything worked, with a few second pause while generating the file.

XI does internal calls, to itself, and that's why this issue arises. Glad to see it resolved though!

Closing this one out, but feel free to make a new thread if you need any assistance in the future.
