Hi

We have licensed Nagios XI, version 5.2.5. After updating Nagios Core from version 4.1.1 to version 4.2.4 lost all hosts and services in menu Services and Host Groups. Instead all hosts and services in remains one lokalhost and services.
I looked at the logs, error in module ndomod.o

I download ndoutils-2.1.2 from source. looked README and did what it says:
COMPILING INSTRUCTIONS

Code: Select all

tar xzf ndoutils-2.1.2.tar.gz
cd ndoutils-2.1.2
./configure
make all

INITIALIZING THE SQL DATABASE
data base nagios is already there, so once did

Code: Select all

cd db
./installdb -u root -p **** database nagios

then
INSTALLING THE NDOMOD BROKER MODULE

Code: Select all

cp src/ndomod-4x.o /usr/local/nagios/bin/ndomod.o
cp config/ndomod.cfg /usr/local/nagios/etc

Add a line in nagios.cfg

Code: Select all

broker_module=/usr/local/nagios/bin/ndomod.o config_file=/usr/local/nagios/etc/ndomod.cfg 
event_broker_options=-1

INSTALLING THE NDO2DB DAEMON

Code: Select all

cp src/ndo2db-4x /usr/local/nagios/bin/ndo2db
cp config/ndo2db.cfg /usr/local/nagios/etc 
/etc/init.d/ndo2db restart

then i checked NagiosCore dashboard, monitoring still only lokalhost and services.

Tell me pls, where and what I missed in their actions?

At this point you will need to wait for the XI 5.4 release, as this takes into account NDO, and the updated Core version.
