Nagios Support Forum

Hi,

It seems that there was a nagios account created, but no home directory created for it, even the home dir path was shown in /etc/passwd. So I followed all your commands.

I just ran again "monitoring wizard" for monitoring a remote windows 7 desktop. After I applied it, it gave me the error right away:
Backend login to the Core Config Manager failed.

Follow the steps in the following section of the FAQ:
http://support.nagios.com/wiki/index.ph ... n_Problems
Post the files reconfig.txt and cmd.txt in code wraps.

It has been more than 1 hour since running tail -f /usr/local/nagiosxi/var/cmdsubsys.log &> cmd.txt, but the output processs has not been completed yet. Is it normal?

No, but it is quite possible if your cons weren't running properly and you applied configuration a bunch of times. these would stack up and have to run sequentially until they are all done..

Here is the cmd.txt file.

Can you share the output of the following commands:

[root@itmon ~]# service crond status

The cron log looks fine. Run the following commands and see if this is going to make a difference:
Have you tried increasing the "max_execution_time" and "memory_limit" values in the "/etc/php.ini" file? You can increase the limits, according to your available resources, and restart apache:

I just input the commands you provided.

Yes, I had increased the value of max_execute and memory limit based on the link before I post the question 2 days ago.

What should I do next?
