Nagios gui in accessible after upgrade.

[netaura]

Hi,
We upgraded our Nagios xi from 5.2.9 and thereafter, our Nagios web interface became inaccessible again, we had to revert back to snapshot.
Please can we get any suggestion as to what could have happened.
I also attached a snapshot of the error from the upgrade.
Thanks.

Could you upload the related log file for us to review? This should have some information. The next step, would be looking at all of your apache log files in /var/log/httpd/. Please post these as well.

My guess, is apache may have updated as well, and if you were using 2.2 and went to 2.4, you'd see a couple things that need to be adjusted.

We don't have the logs because we had to revert back to snapshot.
Please can we have someone from support jump on a call with us, because we are still on Nagios xi 5.2.9.
Thanks!

Thank you, the files work properly on my machine during the upgrade, something else is getting broken, we would need to see your entire upgrade.log or the full output of the errors to proceed further.

When you are experiencing the issue, please run this command (and let it run):

Code: Select all

tail -fn0 /var/log/httpd/*

Then try to pull up the web interface and send the entire output of the tail command.

Also, when you are experiencing the issue, please send the output of this command as well:

Code: Select all

apachectl -t

Here is the requested error_log.

apachectl -t
