Applying Configuration in the command prompt?

I was looking through the forums and I was curious, is ./reconfigure_nagios.sh another way of "applying configuration"?

Kind Regards,

Doron

Actually it IS the Apply Configuration process :)

So what exactly goes on, under the hood, when you click, "Apply Configuration" on the server? When we have our siteminder authentication enabled it hangs only on that part. We removed everything in /nagiosql/ from the siteminder protection. After we did that the script itself started to work, though I am curious why the script is hanging when you click apply configuration in the browser.

You can do a running tail on the actual log to trace what happens when you click Apply Configuration in the browser. Send us the output of where it appears to be getting stuck.

Code: Select all

tail -f /usr/local/nagiosxi/var/cmdsubsys.log

I would move or remove the following directory and see if the issue is resolved:

/usr/local/nagios/etc/cfgprep

The nagios user is trying to read files in that directory but doesn't have permission. Since I'm assuming you're done importing, you can back up those files elsewhere and clear that directory.

It didn't work. When we disable siteminder it completes it, though the info for both look the same (one that finished):

You just renamed the "cfgprep" directory but you left it in the "/etc". Please, move it to another directory for example "/tmp" and try again.

Code: Select all

mv /usr/local/nagios/etc/cfgprep/ /tmp/
tail -f /usr/local/nagiosxi/var/cmdsubsys.log
Apply Configuration.

That got rid of those errors, though it didn't fix the issue:

This is being generated in the error_log for apache:

When I disable siteminder and restart apache it finishes:

Configuration applied successfully.
Success! Nagios Core was restarted with an updated configuration

Do you have short tags enabled in your /etc/php.ini file? If so, disable them and restart apache.

Can you maybe give a brief overview of what siteminder does? If we can understand what better how it interacts with the server we'll maybe have a better chance of understanding what it's breaking.
