I followed the guide and it worked flawlessly.
The only issue I had is:
install-merlin.sh
Had to change the #!/bin/sh to #!/bin/bash for the script to work, it also expects the mysql's root password to be blank; so to get it running I had to put a null password for mysql's root.
Now my issue is..
With the default Nagios setup, there is the localhost host being monitored with a few services, they show up in http://myip/nagos's interface... but not in http://myip/ninja's interface. It shows 0 hosts.
I browsed Merlin's database and I can see the in the "Host" table, there is the one record of localhost.
Tailing merlin's daemon.log:
[1248313905] 7: Inserting check result for service 'PING' on host 'localhost'
[1248313905] 7: sel_val: 7; ipc_listen_sock: 5; ipc_sock: 7; net_sock: 6

We can see good activity without any errors.... Can anyone shed some light as to what could be wrong with my NINJA? :)
Ninja/Merlin were both cloned from GIT at about 2:00PM today and installed.
I did notice if I clicked on Ninja's "Host Group Grid" menu, I get error:
An error was detected which prevented the loading of this page. If this problem persists, please contact the website administrator.
/usr/local/nagios/addons/ninja/application/controllers/status.php [1422]:
Invalid argument supplied for foreach()
Or if I tried to search for localhost using NINJA's search I got:
A database error occurred while performing the requested procedure. Please review the database error below for more information.
/usr/local/nagios/addons/ninja/system/libraries/drivers/Database/Mysql.php [367]:
There was an SQL error: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ') LIMIT 0, 10' at line 7 - SELECT DISTINCT * FROM `host` WHERE `host_name` LIKE '%localhost%' OR `alias` LIKE '%localhost%' OR `display_name` LIKE '%localhost%' OR `address` LIKE '%localhost%' AND `id` IN () LIMIT 0, 10
Please help... thanks !!

Hi Peter,
Thank you for the post; I will be using this tutorial with the latest Nagios/Merlin/Ninja and let the mailing list know of my success.
So far, the Ninja/Merlin combo has fueled me to re-do my Nagios setup to include the two mods, reason for re-doing it is because I want to start the host/service monitoring configuration from scratch.
Thanks.

Hi Mirza
A colleague send the following installation instruction for ubuntu to
the list a few month ago:
# Nagios3:
Settings:
object_cache_file=/var/cache/nagios3/objects.cache
aptitude install nagios-nrpe-plugin nagios-snmp-plugins nsca \
nagios-plugins nagios-plugins-basic nagios-plugins-standard nagios3 \
nagios3-common nagios3-dbg nagios3-doc libdbd-mysql libdbi0 libdbi0-dev \
mysql-server php5-cli php5 php5-mysql
cd /etc/nagios3/
htpasswd -c htpasswd.users nagiosadmin
# Merlin:
mkdir /etc/nagios3/addons
cd /etc/nagios3/addons
git clone git://git.op5.org/nagios/merlin.git merlin-src
cd merlin-src
make
./install-merlin.sh --nagios-cfg=/etc/nagios3/nagios.cfg
--dest-dir=/etc/nagios3/addons/merlin
remove vrml_image from nagios config (bugreport unknown field 'vrml_image' ?)
/etc/init.d/nagios3 restart
./import.php
/etc/init.d/merlind start
# Ninja
cd /etc/nagios3/addons
git clone git://git.op5.org/nagios/ninja.git
mkdir ninja-gui
cd ninja-gui
ln -s /etc/nagios3/addons/ninja/op5build/index.php .
ln -s /etc/nagios3/addons/ninja/application .
cd /etc/nagios3/addons/ninja/op5build
edit ninja.httpd-conf and correct paths
cd /etc/apache2/conf.d
ln -s /etc/nagios3/addons/ninja/op5build/ninja.httpd-conf ninja.conf
/etc/init.d/apache2 restart
edit /etc/nagios3/addons/ninja/op5build/index.php
correct following:
$ninja_base = '/etc/nagios3/addons/ninja';
edit /etc/nagios3/addons/ninja/application/config/config.php
correct following:
$config['nagios_base_path'] = '/etc/nagios3';
$config['nagios_etc_path'] = '/etc/nagios3';
$config['logos_path'] = '/nagios/images/logos/';
$config['pnp4nagios_path'] = false;
# To create the ninja db and import user/password from htpasswd:
cd /etc/nagios3/addons/ninja/install_scripts
./ninja_db_init.sh /etc/nagios3/addons/ninja
./auth_import.php /etc/nagios3/addons/ninja
Then point your browser to <server-ip>/ninja
I hope this help.
