Installing Zabbix on a Raspberry Pi?

Zabbix is a powerful open-source monitoring solution that allows you to monitor many aspects of your infrastructure, including networks, servers, cloud resources and more. With the flexibility of a Raspberry Pi, you can create an energy efficient yet fully-featured Zabbix monitoring appliance suited to small to medium sized environments.

Installing Zabbix on a Raspberry Pi?

Zabbix uses a client-server architecture to actively monitor conditions through agents, SNMP polling, IPMI and custom checks. Its robust alerting allows fast problem resolution by notifying users through email, SMS or custom scripts.

With features including customizable dashboards, reporting, visualization and auto discovery, Zabbix provides deep insight into your environments health.

Why Use a Raspberry Pi

The Raspberry Pi is an inexpensive single board computer created for education that has become a widely used platform for DIY electronics and IT projects.

Some of the main benefits of using a Raspberry Pi for Zabbix include:

  • Low energy usage: Uses around 5 watts of power compared to a full desktop or server
  • Compact size: Fits anywhere with a small footprint
  • Cost savings: Full setup costs less than $100 typically
  • Fan-less: No noisy fans or moving parts with SD card boot

While less powerful than an enterprise server, a Pi has enough CPU, memory, networking and IO capabilities to monitor SMBs effectively.

Installation Requirements

Before we install, there are some base requirements and components we need:

  • Raspberry Pi: Any model from the 3 B and up will work
  • MicroSD Card: 8 GB Class 10 card minimum
  • Power Supply: Appropriate USB-C adapter for Pi model
  • Network connectivity: Wired or wireless
  • Operating System: Ubuntu Server 20.04 LTS
  • Zabbix Server: Version 5.2 other required components

Having these prepared, you can now setup your Pi, get Ubuntu installed and then install the Zabbix software.

Setting Up the Raspberry Pi

With the hardware ready, follow these steps to prep your Pi:

  1. Flash Ubuntu Server 20.04 LTS onto your MicroSD card.
  2. Insert SD card and connect ethernet/wifi and power supply.
  3. Log into your Pi and complete basic setup like username, password and locales.
  4. Perform update of packages: sudo apt update && sudo apt upgrade
  5. Reboot Pi to complete. OS is now ready for Zabbix software.

With Ubuntu configured properly on your Pi, you now have the base OS installed ready to deploy Zabbix.

Installing Zabbix 5.2 Server

We will use the official Zabbix repository from their website to install the components we need:

  1. Add the repository:
    sudo wget
    sudo dpkg -i zabbix-release_5.2-1+ubuntu20.04_all.deb
  2. Update repositories:
    sudo apt update
  3. Install Zabbix server, agent, frontend:
    sudo apt install zabbix-server-mysql zabbix-frontend-php zabbix-nginx-conf zabbix-agent
  4. Create initial database schema:
    sudo mysql
    create database zabbix character set utf8 collate utf8_bin;
    create user zabbix@localhost identified by ‘password’;
    grant all privileges on zabbix.* to zabbix@localhost;
    quit; zcat /usr/share/doc/zabbix-server-mysql*/create.sql.gz | mysql -uzabbix -p zabbix
  5. Configure the database for Zabbix server:
    sudo vi /etc/zabbix/zabbix_server.conf
    Update DBHost, DBName, DBUser, and DBPassword appropriately
  6. Restart Zabbix Server
    sudo systemctl restart zabbix-server zabbix-agent nginx php7.4-fpm

With the steps completed, you now have a running Zabbix 5.2 install on Ubuntu 20.04 LTS tailored for your Raspberry Pi device!

Optimizing the Configuration

To get the most from your Pi Zabbix setup and allow for smoother operations, you should tune the server, proxy, agent and database configurations.

A few key areas to focus optimization are:

  • History/data storage – Compression, aging, indexing, partitioning
  • Housekeeper settings – Control stale data deletion frequency
  • Logging – File sizes, age and rotation
  • Triggers – Filtering, correlating events intelligently
  • Alerting – Fine tune notifications frequency

Adjusting these and reviewing the logs/stats should provide good performance levels and prevent issues arising before they happen.

Securing Your Zabbix Pi

As with any monitoring server that provides access to sensitive systems, hardening the device should be a priority against cyber security threats.

Some best practices for securing your Pi Zabbix deploy include:

  • Use HTTPS with well-signed SSL certificates for front-end access
  • Enable two-factor authentication
  • Restrict administrative logins to VPN or management network
  • Disable unused display/graph features
  • Regular patching and updates for Zabbix and OS
  • Network segmentation monitoring VLANS only
  • Review logs and audit changes regularly

Keeping your Pi locked down tight will ensure your monitoring remains accurate and resilient.

Key Benefits of a Pi Zabbix Setup

After completing your tailored Zabbix Raspberry Pi setup, let’s recap the main advantages this provides:

  • Cost-effective – Very low setup expenditure around $100 typically
  • Space saving – Tiny Pi PCB fits anywhere like shelves or cabinets
  • Energy efficient – Uses max 5-10W power typically
  • Customizable – Modify to suit what you want monitored
  • Expandable – Can add external modules like cameras easily

For lean SMB environments, utilizing a Pi for monitoring infrastructure grants server-like oversight without significant invest or rack space.


Setting up Zabbix on a Raspberry Pi creates is straightforward while providing a fully functional monitoring server. With the lightweight and customizable Ubuntu Pi OS combined with the powerful Zabbix software, you unlock deep infrastructure insights.

Optimizing configurations grants strong performance for metrics and events data collected. While securing with best practices allows resilience against unauthorized access. Raspberry Pi Zabbix deployments deliver reliable and robust monitoring environments cost effectively.

Frequently Asked Questions

  1. What model of Raspberry Pi should I use?
