Hi,

I wanted to troubleshoot an issue with my Nagios XI server and it seems that I receive multiple errors per second in /var/log/httpd/error_log
The error always starts with
PHP Warning: Invalid argument supplied for foreach() in /usr/local/nagiosxi/html/includes/components/nagiosim/nagiosim.inc.php on line 491, referer: XXX
Where XXX can be different URL's as shown below.

Code: Select all

Hi Dennis,

Those messages are coming from a deprecated component that you can remove from the server. Take a backup.

Backing Up And Restoring Your Nagios XI System

And then run the following command to remove this component.

Code: Select all

rm -rf /usr/local/nagiosxi/html/includes/components/nagiosim
Let me know if that resolves the issue for you.

Benjamin

That fixed the issue.
Shouldn't the upgrade delete components that are no longer used ?

Dennis

Glad to hear it is fixed.

We have chosen not to delete this particular component as there are some who had purchased and still use Nagios Incident Manager even though it is no longer supported.
