Zabbix agent setup
I'm using the Zabbix monitoring solution [1]. So I have to install a Zabbix agent on my client distribution to retrieve data.
>> The Zabbix documentation is really complete! Don't forget to check it out if you're using a different version |and|or| want to know more about the installation details. See https://www.zabbix.com/documentation/

Zabbix agent installation
Source: https://www.zabbix.com/documentation/2.2/manual/installation/install_from_packages
Add zabbix repository
wget http://repo.zabbix.com/zabbix/2.2/ubuntu/pool/main/z/zabbix-release/zabbix-release_2.2-1+trusty_all.deb
dpkg -i zabbix-release_2.2-1+trusty_all.deb
apt-get update
Install zabbit agent
apt-get install zabbix-agent
Zabbix agent configuration
See https://www.zabbix.com/documentation/2.2/manual/appendix/config/zabbix_agentd for parameters details.
Edit the Zabbix agent configuration file:
vim /etc/zabbix/zabbix_agentd.conf
Adjust the following settings:
# List of passive zabbix server (comma separation) ~ line 85
Server=172.16.50.223
# List of active zabbix server (comma separation) ~ line 126
ServerActive=172.16.50.223
# Do not override a default hostname, use the O.S hostname instead.
# You MUST comment the Hostname instruction ~ line 137
#Hostname=Zabbix server
# Enable remote command and server push
EnableRemoteCommands=1
ListenPort=10050
ListenIP=0.0.0.0
StartAgents=3
### Option: RefreshActiveChecks
# How often list of active checks is refreshed, in seconds.
RefreshActiveChecks=120
Firewall
For the Zabbix Agent to work, both TCP 10050 (zabbix client) and TCP 10051 (zabbix server) IN + OUT must be open!
See:
Zabbix host registration (server side)
On the Zabbix server, you can now register the new host.

NetBoot client specifics
When you're using NetBoot and tmpfs you'll run into specifics issues. The following part is my return of experience.
Zabbix launcher script
The application requires some files and folders to run. Without these it will always failed to start.
Problem: in our case these files are mount in tmpfs = they will not exist by default. You have to adjust the zabbix startup script to create it!
Edit the Zabbix agent configuration file:
vim /etc/init.d/zabbix-agent
Add the following commands around line 18.
LOG_DIR=/var/log/zabbix
LOG_FILE=$LOG_DIR/zabbix_agentd.log
if test ! -d "$LOG_DIR"; then
mkdir "$LOG_DIR"
touch "$LOG_FILE"
chown -R zabbix:zabbix "$LOG_DIR"
fi
