CentOS
7.7.1908
64 bit
VMWare Image install
Nagios XI 5.6.8

New users created via the web interface and seeing the following error message rather than the appropriate service information.
"SQL Error [ndoutils] : You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near ') ORDER BY obj1.name1 DESC LIMIT 100000' at line 9

Sorry for the duplicate submission, I left the system info off the original post and was unable to edit it.

Hello @pbarnett865,

Looks like you are new to the support forum, so I would just like to say thanks for joining!

I just want to confirm that you did install from our VMware image as it should have installed the correct version of MariaDB. A few more questions:

1. Did you import these users from Active Directory?

2. Are there any other packages installed on the server that may be causing conflicts?

3. Can you PM your system profile?

To send us your system profile.
Login to the Nagios XI GUI using a web browser
Click the "Admin" > "System Profile" Menu
Click the "Download Profile" button
Save the profile.zip file and share this in a private message and then reply to this post to bring it up in the queue.

Long time lurker so to say.

Yes, I installed NagiosXI via the image provided.
VM Tools would be the only thing I can think of that may have been installed.
The users were imported via LDAP query to our AD domain.
I sent the system profile via pm.

Thanks for your help.

Hello @pbarnett865,

Thanks for answering those questions. I just sent you a PM regarding the system profile.

Posted: **Wed Dec 11, 2019 1:10 pm**

I resubmitted the profile.

Hello,

Thank you for sending over the System Profile. I'm seeing authentication errors in the Apache log like this:

ser glouvier: authentication failure for "/nagios/cgi-bin/status.cgi": Password Mismatch

Please run through the following steps:

1. Go to Admin > Administrative Task ( on the main page) > Reset Security Credentials

2. Next, go to Users > Manage Users and from the Actions menu Masquerade as one of the Non-Administrative users. Does the error message still persists?

If so, run, the following tail command and then load the services page (producing the error) and post the full output to the thread.

Code: Select all

tail -f /var/log/httpd/*error_log

I'm no longer seeing that specific error, but it takes forever for the page to load, and I'm seeing these errors in the log you requested.
The services assigned to this user randomly appear and disappear. The user name is ptest1.

Hello,

Thanks for your patience, I'm not sure why it would randomly appear and disappear as it looks to be a permissions issue based on the log output.

A couple more items to verify, post the output to the following.

1. Do you have SELinux enabled on this server?

Code: Select all

getenforce

2. Let's verify the correct permissions on the cgi scripts.

Code: Select all

ls -lh /usr/local/nagios/sbin

3. Make sure the Nagios user account is not expired.

Code: Select all

chage -l nagios

4. Check the /etc/group file.

Code: Select all

cat /etc/group|grep nagios

Thank you for the help.
I've also noticed the monitoring engine process doesn't seem to run according to the web interface.

Hello,

Thanks for posting the permissions settings, that looks normal. My understanding is that the server is working better but now you're noticing a lag in processing? Is this correct? If so, let's up the message queue and PHP settings on this system.

1. Perform a full restart, clear the messages queues and repair the databases.

Code: Select all

systemctl stop crond
systemctl stop npcd
systemctl stop nagios
systemctl stop ndo2db
pkill -9 -u nagios
for i in $(ipcs -q | grep nagios |awk '{print $2}'); do ipcrm -q $i; done
rm -rf /usr/local/nagiosxi/var/dbmaint.lock
rm -rf /usr/local/nagiosxi/var/event_handler.lock
rm -rf /usr/local/nagiosxi/scripts/reconfigure_nagios.lock
systemctl restart mysqld || systemctl restart mariadb
cd /usr/local/nagiosxi/scripts
./repair_databases.sh
systemctl start npcd
systemctl start crond
systemctl start nagios
systemctl start ndo2db

2. Next, follow the article below to Increase the settings.
NDOUtils - Message Queue Exceeded

3. Increase the default resources available for PHP
Nagios XI - Optimizing The PHP Settings File

Let it run for a while and let me know if the issue persists or not.
