https://support.nagios.com/forum/viewto ... 16&t=30807

Also our UAT environment producing these signs, same operating system same version, much less service count.

5.8.3 version changelog not showing these type of correction.

but not sure it is help or not, but on UAT environment it is worked well.

I could make profile, but its size is arround 500MB on our PROD environment.

Before following the steps below, please do this and see if it resolves the issue:

Please go to Configure > Core Config Manager > Tools > Config File Management:
- Click the Delete Files button (don't worry, it's safe, they will be rewritten)
- Then click the Write Configs button
- After they are done being written, apply configuration and validate.

If that doesn't resolve the issue you're likely hitting a bug in the new NDO3 (we would need a copy of your profile to validate what is occurring). I would upgrade to XI 5.8.3 where it has the latest NDO3 fixes, then apply configuration to see if that resolves your issue.

If you still have the issue on XI 5.8.3, then you'll need to downgrade NDO3 back to NDO2DB to resolve the issue:

Run these commands as root:

Code: Select all

systemctl stop nagios
cd /tmp
rm -rf /tmp/nagiosxi
wget https://assets.nagios.com/downloads/nagiosxi/5/xi-5.6.14.tar.gz
tar zxf xi-5.6.14.tar.gz
cd /tmp/nagiosxi
./init.sh
cd /tmp/nagiosxi/subcomponents/ndoutils
./install
systemctl enable ndo2db

If you have an offloaded database you will need to edit your /usr/local/nagios/etc/ndo2db.cfg file and update these before running the next command to start it up:
- You can get the info from your /usr/local/nagios/etc/ndo.cfg or from /usr/local/nagiosxi/html/config.inc.php

db_host
db_port
db_user
db_pass

Then run this command to start it up.:

Code: Select all

systemctl start ndo2db

Then edit your /usr/local/nagios/etc/nagios.cfg and make sure this line is uncommented/add it if needed:

Code: Select all

broker_module=/usr/local/nagios/bin/ndomod.o config_file=/usr/local/nagios/etc/ndomod.cfg

Make sure all occurrences of this line are commented:

Code: Select all

#broker_module=/usr/local/nagios/bin/ndo.so /usr/local/nagios/etc/ndo.cfg

Then start the nagios service:

Code: Select all

systemctl start nagios

Then apply configuration.
