Cannot import host using NCPA Monitoring Wizard

[genna]

Hi,
I have installed and configured NCPA listner on a host and checked connectivity from Nagios XI to that host.
I have started NCPA Wizard and went through steps 1,2,3. Press "Finish" - system went to "Waiting for configuration verification....". After 5 minutes it gave an error :
Configuration Error
An error occurred while attempting to apply your configuration to the monitoring engine. Contact your Nagios administrator if this problem persists.

I can see following lines in httpd/error_log

It happens on two Nagios XI servers one running 5.4.9 the other 5.4.10 and both ruing PHP 5.6

What is the NCPA version that you install on the client machine? What is the version of the "NCPA Agent" wizard that you are currently using?

Admin->Manage Config Wizards

Run the following command on the Nagios XI server and show the output:

Code: Select all

/usr/local/nagios/libexec/check_ncpa.py  -V

[genna]

What is the NCPA version that you install on the client machine?

2.0.5

What is the version of the "NCPA Agent" wizard that you are currently using?

Admin->Manage Config Wizards

1.4.4

Run the following command on the Nagios XI server and show the output:

Code: Select all

/usr/local/nagios/libexec/check_ncpa.py  -V

Code: Select all

 
[root@int-dev-nag-wm ~]# /usr/local/nagios/libexec/check_ncpa.py -V
check_ncpa.py, Version 1.1.1
[root@int-dev-nag-wm ~]# /usr/local/nagios/libexec/check_ncpa.py -H 10.105.160.111 -t TcV8ZuVhsV7cgAnI -M   'memory/virtual/percent'
OK: Percent was 20.20 % | 'percent'=20.20%;;;
[root@int-dev-nag-wm ~]#

So it appears that there are no connectivity issues between XI server and a client machine.

[kyang]

Okay, I see that you have an older version of the Config Wizard.

Update it by going to Admin --> Manage Config --> Check for Updates --> scroll down to the NCPA wizard and install update.

Once finished, you should be on 1.5.1

After that try using the Config Wizard again, and tell us the result.

[lmiltchev]

I am not sure what procedure you followed while upgrading the PHP to 5.6, but you need to make sure that pear dependencies are installed.

- Must install ssh2 (either using pecl or by using php<version>-pecl-ssh2 if available) - run each command separately one at a time

Code: Select all

yum install -y libssh2-devel
pecl install ssh2
echo "extension=ssh2.so" > /etc/php.d/ssh2.ini

- Must install HTML_Template_IT from pear

Code: Select all

pear install HTML_Template_IT

- You must restart apache again

Code: Select all

service httpd restart

- Restart services

Code: Select all

service nagios stop
service ndo2db restart
service nagios start

Let us know if this solved your issue. Thank you!

Hi @kyang
Template Update did not help

Hi @lmiltchev
I have done those steps when moved to PHP 5.6
Also it appears the problem is not limited to NCPA Monitoiring Wizard. It happens every time I apply configuration change. When I apply config change I can see in cmdsubsys.log a lot of messages :

.Another reconfigure process is still running, sleeping...

Eventually it errors out with following entry in the log:

[lmiltchev]

I see "500 Internal Server Error" in the log. Are you using a proxy or SSL?

Do you see the same error, when you run reconfigure_nagios.sh from the command line as nagios user?

Code: Select all

su nagios
cd /usr/local/nagiosxi/scripts
./reconfigure_nagios.sh

Have you tried resetting the permissions?

Code: Select all

/usr/local/nagiosxi/scripts/reset_config_perms.sh

Is the nagios or apache user accounts expired (not active)?

Code: Select all

chage nagios -l
chage apache -l

Do you see config errors when you run the Write Config Tool from the web UI (CCM > Tools > Config File Management > Write Configs > Verify Files)?

What is the "max_execution_time" value in the php.ini file?

Code: Select all

grep max_execution_time /etc/php.ini

[genna]

I see "500 Internal Server Error" in the log. Are you using a proxy or SSL?

I'm not sure I understand the question. Are we using proxy or SSL between what and what? The error is appearing inside nagios log performing a nagios internal command. The 500 response it to http://localhost request so I doubt either ssl or proxy is in play.

Do you see the same error, when you run reconfigure_nagios.sh from the command line as nagios user?

Code: Select all

Have you tried resetting the permissions?

I have tried that and it did not help

chage apache -l

No. They are set to never expire

Do you see config errors when you run the Write Config Tool from the web UI (CCM > Tools > Config File Management > Write Configs > Verify Files)?

I don't think so. When I press "Write Configs" screen goes blank ( except menus on top and left . No errors in the cmdsubsys.log. "Verify Files" works

What is the "max_execution_time" value in the php.ini file?

Code: Select all

grep max_execution_time /etc/php.ini

Code: Select all

max_execution_time = 60

Can you send us your system profile from Admin -> System Config -> System Profile -> Download Profile

You can either PM me or post it through here.

This will give us access to many of the logs we would otherwise ask for individually. If security is a concern, you can unzip the profile take out what you like, and then zip it up again. We may end up needing something you remove, but we can ask for that specifically.

Hi @kyang
I have posted profile in PM.
Thanks
