Installing the NDOUtils addon

The NDOutils addon stores Nagios related data to MySQL database.

Create Database:

create database nagios default character set='utf8' default collate='utf8_general_ci';
grant SELECT, INSERT, UPDATE, DELETE on nagios.* to 'nagios'@'localhost' identified by 'secret';

Create tables:

cd /unpacked-src-folder/db
./installdb -u root -p rootpw -h localhost -d nagios

Source used: ndoutils-1.4b9

cd /unpacked-src-folder
./configure --enable-mysql --disable-pgsql
make

As told by the README file, manual install the compiled programs and config files¹⁾:

cp src/ndomod-3x.o /usr/local/bin/ndomod.o
cp src/ndo2db-3x /usr/local/bin/ndo2db

cp config/ndomod.cfg /etc/nagios/
cp config/ndo2db.cfg /etc/nagios/

Place the ndo2db init script to /etc/rc.d/init.d/

Edit the /etc/nagios/ndomod.cfg to your needs. Normally set these:

output_type=unixsocket
output=/var/lib/nagios/ndo2db.sock
buffer_file=/var/lib/nagios/ndomod.tmp
data_processing_options=-1

Edit the /etc/nagios/ndo2db.cfg to your needs. Normally set these:

socket_name=/var/lib/nagios/ndo2db.sock
db_pass=secret

Enable Nagios to use NDO2DB addon by settings these in /etc/nagios/nagios.cfg:

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