Upgrade Issues with 5.7 and still in 5.7.1

[kketchmark]

Started to get this error after upgrade from 5.6.12 to 5.7. Upgrade said everything was ok and no issues.

When any User or Admin clinks on a host or service the page fails to display the info. If I open the Chrome Development Tools and watch for errors, I get the following, GET https://nagiost.stthomas.edu/nagiosxi/i ... &dest=auto 500 (Internal Server Error)

I then look in the Apache ssl_error_log file and see this error. [Fri Jun 12 08:29:42.866528 2020] [:error] [pid 5827] [client 140.209.74.215:36480] PHP Fatal error: Call to undefined function get_backend_xml_data() in /usr/local/nagiosxi/html/includes/components/historytab/historytab.inc.php on line 102, referer: https://nagiost.stthomas.edu/nagiosxi/i ... w=services

I also had this error yesterday on version 5.7. Searched and seen a lot of errors so I figured I would wait and update to 5.7.1, but I see the errors are still there. Everything else seems to be working.

System config:
OS: RedHat 7.7 64bit
Running on VMware
Nothing special for system, it is being ssl offloaded via F5 LTM's but I also get the error going direct with out the F5 in place.

I see a ticket was opened with the same issue.

We will be locking this thread and will respond through the ticket

Removing the history tab component will fix the

Code: Select all

PHP Fatal error: Call to undefined function get_backend_xml_data() in /usr/local/nagiosxi/html/includes/components/historytab/historytab.inc.php 

error, as well as the blank host and service pages:

Code: Select all

tar -cf /root/history-tab-saveforlater.tar /usr/local/nagiosxi/html/includes/components/historytab
rm -rf /usr/local/nagiosxi/html/includes/components/historytab

I doubt Troy(a.k.a. Box293) is going to work on an update to the plugin. Can the nagios guys take a took at possibly patching it? I love that tab and would hate to lose it when I upgrade.

I "fixed" it on my dev host by commenting out one line. You'll lose Nagios Comment history but at least not all the other items. Open the file

Code: Select all

/usr/local/nagiosxi/html/includes/components/historytab/historytab_do_stuff.php

and comment out line 49

Code: Select all

#$xml_nagios_comments = get_backend_xml_data($args_nagios_comments);

Thanks for posting that update. Both Scott and I took a quick look but couldn't find a replacement function that would meet the needs given the current codebase. The component would need to be modified as the functions it uses no longer exist in the code.

Thanks for the info @BanditBBS!

I filed a feature request for patching the history tab component. Please keep in mind that the decision to implement the enhancement is at the discretion of our development team.
