Nagios Support Forum

CentOS Linux release 7.3.1611 (64-bit)
Manual install of XI, recent manual upgrade to 5.4.3

I'm trying to add some passive checks, but the Unconfigured Objects wizard isn't cooperating. On my monitored host (Windows Server 2008 R2 x64, with NCPA 2.0.3), I have already configured some active checks which are working. Then I configured the passive checks, which also appear to be working inasmuch as they show up as unconfigured objects on my Nagios XI host. However, when I select the checkbox next to the host name and then the gear icon to configure the selected checks, that frame just goes blank. It doesn't matter if I reload the frame. I get the same result whether I use Firefox or Chrome. SELinux is disabled, for what it's worth.

Editing to add that if I manually configure the services for the passive checks, I get the results I'm expecting. I would rather not do that for over 100 checks, though.

Can you share all of your Apache logs? They're typically found here:
If you're trying to configure a few hundred or so services, you may need to increase the default PHP memory limits. In /etc/php.ini, try increasing this value:
Bump it up to 1024M, service httpd restart to apply the changes, and see if that resolves the issue. If not, the Apache logs should have some indication of what's going on.

Good call on the Apache logs, thank you. The error_log file had messages like this: I had installed the NetApp SANtricity plug-in a while back. On a hunch, I uninstalled it. As soon as I did, the Unconfigured Objects wizard worked and I was able to add the passive checks to their host.
