Sorry for the delay,
I am in the process of doing the upgrade for Nagios Core and NDOUtils. Will let you know the results after it is completed and give it some time to test.

After installing the Nagios Core and Ndoutils on a non-production system. The Sysem Status shows the Database Backend is not running, but I have checked the process list, database, and logs and ndo2db is runnning and processing. Is this false alarm suppose to happen?

I can see from the ps output that the ndo2db is running, but can you run the following command, and show the output anyway?

I was able to recreate the issue some time ago - just wanted to make sure you were getting the same output. Our developers have been made aware of the problem. I already filed an internal bug report (task_id=9434) on the issue.

Is this only a cosmetic impact or does it also have other impacts to the Nagios XI system?

It does look like a "cosmetic" issue only, but I am pretty sure you could fix it by reinstalling NDO using the "--with-init-type=sysv" argument.

did a re-install with the option, but I am still getting the same results. Will work to deploy this out to the production server and will let you know if that helps the original problem.

Let us know how it went.
FYI, the following steps worked for me:
Code: Select all
service nagios stop
service ndo2db stop
rm -rf /usr/local/nagios/var/nagios.lock /usr/local/nagios/var/ndo.sock
cd /tmp
rm -rf *
wget https://github.com/NagiosEnterprises/ndoutils/archive/maint.zip
unzip maint.zip
cd ndoutils-maint
./configure --with-init-type=sysv
make all
make install
make install-init
cd db
./upgradedb -d nagios -h localhost -u ndoutils -pn@gweb
service nagios stop
service ndo2db restart
service nagios start
[root@localhost db]# ps -ef | grep ndo | grep -v grep
nagios 20659 1 0 13:16 ? 00:00:00 /usr/local/nagios/bin/ndo2db -c /usr/local/nagios/etc/ndo2db.cfg

FYI. After installing ndoutils-main or ndotils-2.1.1 on CentOS Linux release 7.2.1511 (Core). The service ndo2db stop, does not stop the service. I need to do a kill on the pid to get it to stop.
Still in the process of doing the upgrade of the production system.
