Installation of NDOutils

Note: I haven't found NDO on the prerequisites for centreon but it is advisable to install the addon nonetheless. You will find the latest version on the official Nagios website http://www.nagios.org:

Note: Ubuntu community provides ndoutil version 1.4b7-2 but this package depends on nagios2 (version 2.11) (info 17/06/08)

prerequest

install mysql dev api 

# sudo apt-get install libmysqlclient15-dev

download & make

download the archive 

# cd /usr/local/src
# wget http://surfnet.dl.sourceforge.net/sourceforge/nagios/ndoutils-1.4b7.tar.gz

Unpack the archive and change the directory: 

# tar -xzf ndoutils-1.4b7.tar.gz
# cd ndoutils-1.4b7
# vi README

configuration and installation: 

# ./configure --prefix=/usr/local/nagios/ --enable-mysql --disable-pgsql --with-ndo2db-user=nagios --with-ndo2db-group=nagios
# make


manual installation (no make install :-()

After creating the binaries and libraries they have to be copied 

 cp ./src/ndomod-3x.o /usr/local/nagios/bin/ndomod.o
 cp ./src/ndo2db-3x /usr/local/nagios/bin/ndo2db
 cp ./config/ndo2db.cfg /usr/local/nagios/etc/
 cp ./config/ndomod.cfg /usr/local/nagios/etc/
 sudo chmod 774 /usr/local/nagios/bin/ndo*
 sudo chown nagios:nagios /usr/local/nagios/bin/ndo*

enable ndo module into nagios

Extracted from ndo README

3.Add a line similiar to the following to the *main* Nagios config file (usually /usr/local/nagios/etc/nagios.cfg):

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

The config directive above will cause Nagios to load the NDOMOD event broker the next time it starts. Of course, this requres that you compiled Nagios with support for the event broker in the first place. :-)

4.Make sure you have a line similar to the following in the *main* Nagios config file (usually /usr/local/nagios/etc/nagios.cfg):

event_broker_option_=-1

That directive will cause the Nagios daemon to send data to the NDOMOD module. Without that option, NDOMOD won't get any information.

# End of this script

then add it to your config to load it automatically when starting/restarting your server : 

# sudo update-rc.d ndo2db defaults
# chmod +x /etc/init.d/ndo2db

The NDOUtils are installed. Later on we have to make some adjustments.
