/var/log/httpd/ssl_error_log PHP Notice and Warning Messages

[andyb4u]

Hi,

We have noticed that the /var/log/httpd/ssl_error_log file is full of thousands of lines such as:

Code: Select all

[Mon Sep 27 03:38:02.018401 2021] [:error] [pid 13054] [client X.X.X.X:60192] PHP Notice:  Trying to get property of non-object in /usr/local/nagiosxi/html/includes/dashlets/gauges/gauges.inc.php on line 310, referer: https://NAGIOS/nagiosxi/includes/components/xicore/status.php?show=hostdetail&host=SOMEHOST
[Mon Sep 27 03:38:02.018433 2021] [:error] [pid 13054] [client X.X.X.X:60192] PHP Warning:  Invalid argument supplied for foreach() in /usr/local/nagiosxi/html/includes/dashlets/gauges/gauges.inc.php on line 310, referer: https://NAGIOS/nagiosxi/includes/components/xicore/status.php?show=hostdetail&host=SOMEHOST

The log file is nearly 900MB in size.

Are these messages an indication of an actual issue or can they be ignored?

Regards,
Andy

For info - we have also looked at https://support.nagios.com/kb/article/n ... e-611.html and do not see any of the errors mentioned. The following are set in php.ini:

max_input_vars = 50000
memory_limit = 1024M
max_execution_time = 180
max_input_time = 180

Hi Andy,

The following entry in the php.ini file will disable those notices. They advisory messages and do not indicate a fatal error.

Code: Select all

 
// Turn off Notices and Deprecated Warnings
error_reporting = E_ALL & ~E_DEPRECATED & ~E_NOTICE

Remember to re-start Apache after making any changes.

Code: Select all

systemctl restart httpd

Thanks for pointing that out in the article, we are going to update our kb additional instructions.

Thanks,
Benjamin

Hi Benjamin,

Thanks for that info. I made the change and do not see any 'PHP Notice' messages being logged anymore.

We are still getting some 'PHP Warning' messages being logged, such as:

Code: Select all

[Thu Oct 21 09:37:55.486035 2021] [:error] [pid 28087] [client X.X.X.X:51578] PHP Warning:  Invalid argument supplied for foreach() in /usr/local/nagiosxi/html/includes/dashlets/gauges/gauges.inc.php on line 310, referer: https://NAGIOSXI/nagiosxi/includes/components/xicore/status.php?show=hostdetail&host=SOMEHOST

Should we expect see some PHP Warning messages, such as this, after making the change?

Regards,
Andy

Hi Andy,

Please change it to the following, and let me know if you see any more warning messages logged.

Code: Select all

 
// Turn off Notices and Deprecated Warnings
error_reporting = E_ALL & ~E_DEPRECATED & ~E_NOTICE & ~E_WARNING

Remember to re-start Apache after making any changes.

Code: Select all

systemctl restart httpd

Hi Benjamin,

That has worked. I don't see any more PHP Warning or PHP Notice messages.

Thanks for your help.
