Nagios Support Forum

Try increasing the max execution time for a php script in your /etc/php.ini file and see if that does anything. Crank it up to 60 seconds as a test.

No change.

Do you have any special configurations on your system, such as a proxy, or SSL?

We're redirecting http traffic to https.

On a sidenote, we generally recommend the latest release, as it has the latest features and bug fixes.

We started out with the ( I think 2009R1.3C ) VM you had released. When we had added most of our clients, we took a snapshot of the vm. When this same problem had happened, we upgraded to the newest version at the time ( 2009R1.3D ) but that didn't resolve the problem. When we rolled back to the snapshot the system was working correctly, so I upgraded to it's current version ( 2009R1.3G ) and the system was still working correctly. The system had been running about 2 weeks when I noticed it again started the behavior I created this thread for.

In what manner or how did you redirect?

I added:

RewriteEngine On
RewriteCond %{HTTPS} off
RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI}

to the httpd.conf

Ok, I was going over my notes and in /etc/httpd/conf.d/nagiosxi.conf, line 2, I had uncommented "SSLRequreSSL"

Commenting out the Rewrite lines, and re-commenting "SSLRequireSSL" -seemed- to resolve my problem.

So what's the proper way to force https for nagios without breaking it?

You should just be able to go to:
-Configure
-Run Monitoring Wizard
-Website
-Enter URL
-Check that Use SSL is enabled and port along with whatever Services you would like monitored
-Continue through next steps

Hopefully this helps!

Would doing the http rewrite cause any problems with nagiosxi?

I'm not sure why, reverting these changes appears to have resolved my issue?

I have also tried a rewrite from there with non-functioning results if I recall correctly.

Is this a bug?

Or is there another way to use redirect/force https use in nagiosxi?

I wouldn't say we have a "right" way to force SSL on Nagios XI. I know many users have done it, some with mixed results. Nagios XI should detect https, but I know the CCM requires that https must specified manually in the Configure->Core Config Manager->Config Manager Admin->Config Manager Settings page. Actually, that could have been the issue you were running into, since the reconfigure_nagios.sh and the Apply Configuration calls CCM scripts to execute. We also just posted a fix for R2011 that should also detect https for grabbing the performance graphs as well. So long story short, if you find a way to force https site-wide and get it working correctly, if you could post what you did, we'll probably repost it on our wiki and document it as the "right" way .
