Upgrade to NDO3

Hi,
I'm want to upgrade to NDO3 on my test system before doing it in production, but not sure about the process of doing it.
The procudure "Upgrading to NDO 3 after having been downgraded in newer versions of Nagios XI" describe here seems not to be totally complete:
https://support.nagios.com/kb/article/u ... i-885.html
1) Do I really need to install NDO3 part? Should not be already there? should I not just need to change the nagios.cfg file to point to NDO3? I can see the ndo file that it's related to NDO3 to my understanding:
root@plgesmon03[/tmp/nagiosxi]# ls -ltr /usr/local/nagios/bin/ndo.so /usr/local/nagios/etc/ndo.cfg
-rwxrwxr-- 1 nagios nagios 1036208 Feb 5 13:48 /usr/local/nagios/bin/ndo.so
-rw-rw-r-- 1 apache nagios 733 Feb 5 13:55 /usr/local/nagios/etc/ndo.cfg
2) What I do with NDO2 process /usr/local/nagios/bin/ndo2db?
On my test system:
Red Hat Enterprise Linux release 8.10 (Ootpa)
Nagios XI 2024R1.3.4
NDO2DB 2.1.4

Hi @steph007,
Thanks for your question.
You should be good to go with simply changing over nagios.cfg to point to ndo3 and restarting the nagios process.
You should be able to kill the NDO2 process once nagios is restarted.

Does not work.
I can see all services and all hosts in Operations Center , but I cannot clic on a service to get the detail and on the host directly, I don't see any services.
In the error log, this is what I have:

If you didn't already, try running the full list of commands in the doc you referenced. Your database may be missing some tables set up by the install (among other things).
Thank you!

In the doc I referred, I don't see any tables creation documentation.

Someone can give a hand for this?

To update the missing tables manually to see if it works, run this as root on the XI server and it needs to be able to access the internet.
Code: Select all
cd /tmp
rm -rf nagiosxi xi*.tar.gz
wget https://assets.nagios.com/downloads/nagiosxi/2024/xi-2024R1.3.4.tar.gz
tar xzf xi-2024R1.3.4.tar.gz
cd /tmp/nagiosxi/subcomponents/ndo
tar xvfz ndo-3.1.1.tar.gz
Stop the nagios process
Run this script to get the MYSQL database passwords
Code: Select all
/usr/local/nagiosxi/scripts/get_mysql_passwords.sh
Use the MySQL root password: in place of the xxxxxxxxxxxxxx in the next commands
Code: Select all
mysql -u root -pxxxxxxxxxxxxxx nagios </tmp/nagiosxi/subcomponents/ndo/ndo-3.1.1/db/upgrade-from-3.0.7.sql
echo 'truncate nagios_hoststatus; truncate nagios_hosts; truncate nagios_services; truncate nagios_servicestatus; truncate nagios_servicechecks; truncate nagios_hostchecks; truncate nagios_downtimehistory; truncate nagios_commenthistory;' | mysql -u root -pxxxxxxxxxxxxx nagios
echo "truncate table xi_events; truncate table xi_meta; truncate table xi_eventqueue;" | mysql -u root -pxxxxxxxxxxxxx nagiosxi
mysqlcheck -f -r -u root -pxxxxxxxxxxxxx --all-databases --use-frm |grep -vwE "note"
Start the nagios process
Check the /usr/local/nagios/var/nagios.log for any NDO-3: query and if none are found, check the statuses in the XI interface to see if they are updating.
If so, then you are good to go.

Thank you!
On my test system, it seems has done the job. No error into the nagios.log about "Table... doesn't exist" and look good when navigating with the console (to see Services, Hosts and Scheduled Downtime).
I would like to do the same on my production Nagios XI, but I would like to be sure what has been done to fix the problem. Not sure about the command with "truncate". Can it affect the prod?
In prod I'm still in Nagios XI 2024R1.1.5 because I wait to fix the issues with NDO before upgrading. The solution propose for Nagios XI 2024R1.3.4 will work? Of course, I suspect that I need to replace the package for "wget
https://assets.nagios.com/downloads/nag ... 1.5.tar.gz"

The truncate's only remove temporary data that will get recreated when the services are started after the repair so it is safe to run them on the prod server.
I have updated the command for XI 2024R1.1.5 and they are below all in one code block.
Code: Select all
cd /tmp
rm -rf nagiosxi xi*.tar.gz
wget https://assets.nagios.com/downloads/nagiosxi/2024/xi-2024R1.1.5.tar.gz
tar xzf xi-2024R1.1.5.tar.gz
cd /tmp/nagiosxi/subcomponents/ndo
tar xvfz ndo-3.1.0.tar.gz
systemctl stop nagios
Run this script to get the MYSQL database passwords
Code: Select all
/usr/local/nagiosxi/scripts/get_mysql_passwords.sh
Use the MySQL root password: in place of the xxxxxxxxxxxxxx in the next commands
Code: Select all
mysql -u root -pxxxxxxxxxxxxxx nagios </tmp/nagiosxi/subcomponents/ndo/ndo-3.1.0/db/upgrade-from-3.0.7.sql
echo 'truncate nagios_hoststatus; truncate nagios_hosts; truncate nagios_services; truncate nagios_servicestatus; truncate nagios_servicechecks; truncate nagios_hostchecks; truncate nagios_downtimehistory; truncate nagios_commenthistory;' | mysql -u root -pxxxxxxxxxxxxx nagios
echo "truncate table xi_events; truncate table xi_meta; truncate table xi_eventqueue;" | mysql -u root -pxxxxxxxxxxxxx nagiosxi
mysqlcheck -f -r -u root -pxxxxxxxxxxxxx --all-databases --use-frm |grep -vwE "note"
systemctl start nagios
The NDO package is a different version so I updated that for you.
Thank You.
