Errors in /var/log/httpd/error_log

We are seeing a ton of these errors (2100+ today alone) in /var/log/httpd/error_log (and this seems to have been going on for quite a while):
Code: Select all
Undefined variable: searchstring in /usr/local/nagiosxi/html/includes/utils-menu.inc.php on line 1741, referer: http://nagios.redacted.com/nagiosxi/index.php?
We're running version XI v5.4.3
Any one else seeing this?

What you are seeing are only PHP notices about a variable that is being used but it was not defined in the PHP file. The line does say that it is an error but it really is just a notice and can be ignored.
If you want to stop logging of those messages, you can edit the /etc/php.ini file on the Nagios server.
Find the error_reporting option in the file and change it to the example below.
Code: Select all
error_reporting = E_ALL & ~E_DEPRECATED & ~E_NOTICE
Save the file and and restart the Apache process to load the changes by running the following as root.
What that line does is to continue to log the errors except Depreciated messages and Notices.
Please post if you have any more questions.

Here is my original line:
Code: Select all
error_reporting = E_ALL & ~E_DEPRECATED
and after adding the new line:
Code: Select all
error_reporting = E_ALL & ~E_DEPRECATED & ~E_NOTICE
and restarting apache via:
Still no joy. Errors are still being logged.

Did you restart the Apache process?
Are they coming in as PHP Notices or PHP Warnings?

Thanks for pointing this out.. We had an undefined variable in the code, which will be resolved in the next release.
