Monitoring my Raspberry Pi network behind NAT is easy using OpenVPN and Zabbix agent/server.
In a few cases, I need to monitor hosts without any possibilities to install OpenVPN and Zabbix agent on it (switchs, routers, wemos, arduinos…).

Once the server is ready, we can start to configure our agents.
Install the zabbix-agent :
sudo apt-get install zabbix-agent
Edit the configuration file :
sudo vi /etc/zabbix/zabbix_agentd.conf

apt-get install nginx postgresql php php-cli php-fpm php-pgsql php-bcmath php-mbstring php-gd php-xml zabbix-server-pgsql zabbix-frontend-php
Edit the file:
vim /etc/apt/apt.conf.d/10periodic
And check that it as follow:
APT::Periodic::Update-Package-Lists "1";
APT::Periodic::Download-Upgradeable-Packages "0";
There is two modes for Zabbix checks:
– Passive check : a simple data request. Zabbix server or proxy asks for some data (for example, CPU load) and Zabbix agent sends back the result to the server.
– Active check : the agent must first retrieve from the server(s) a list of items for independent processing. Then the agent then periodically sends the new values to the server(s).
Monitoring a Zabbix agent behind a firewall or a NAT without any port redirection requires to use the active mode.
It’s not recommended to monitor over internet without using a VPN.

Zabbix is an enterprise open source monitoring solution for networks and applications.
The Zabbix monitoring system is divided in 3 sub-systems :
– Zabbix server : Collect and store data from the devices.
– Zabbix frontend : Render the data and manage the web UI.
– Zabbix agent : Run locally on the different devices to be monitored.
