Overview

With a quickly growing HomeLab that contains many servers/services/devices I am starting to see the importance of being able to monitor all these ‘things’ from a central location. My understanding is that the goal of Zabbix is to do exactly this. So lets give it a go!

Installation

Initially i figured I would just install Zabbix in Docker like I do for most other services, but i quickly realized that the docker-compose would get messy pretty quick (see here for a sample). After looking over the install options on the Zabbix site, i realized that they offer a virtual appliance that can be run on most hypervisors (I run proxmox which supports the qcow2 KVM disk format). Here’s my steps for installing the virtual appliance in Proxmox (additional installation details can be found on the Zabbix appliance documentation):

Create a Proxmox Virtual Machine

When creating the VM, you can use all the default options, just give it a name and remove the HardDisk after the VM is created (we will add the Zabbix appliance disk later).

Download the Appliance

# From the proxmox shell run the following to download the appliance
# Note: Right click the Zabbix appliance download link to get the latest version
wget https://cdn.zabbix.com/zabbix/appliances/stable/5.2/5.2.5/zabbix_appliance-5.2.5-qcow2.tar.gz

Unzip the Appliance

tar -xvzf zabbix_appliance-5.2.5-qcow2.tar.gz

Import the Appliance Disk to the Virtual Machine

# Note: Change the vm id, the appliance version and the storage type below
#       (you may need to use 'local' if you are not using 'zfs')
qm importdisk 105 zabbix_appliance-5.2.5.qcow2 zfs

# Cleanup unneeded files
rm -rf zabbix_appliance-5.2.5-qcow2
rm zabbix_appliance-5.2.5-qcow2.tar.gz

Update VM Options

At this point you’ll want to make sure your VM is set to boot from the imported disk and to start on boot.

Assign Static IP Address (Optional)

Note: At this point it may be helpful to assign a DHCP Static mapping so your VM will receive a static IP address from your Router. This is how I did it in OPNSense:

Start VM

Now that we’ve got the VM setup, go ahead and start it up! The default login credentials were:
User: root
Pass: zabbix
Note: The default front-end web interface default login is shown in the console below:
User: Admin
Pass: zabbix

Log Into the Web Interface

In your browser navigate to the IP address of your Zabbix VM:

Congratulations. You have have a running Zabbix Instance! Don’t forget to finish configuring and securing your instance. A few items I addressed immediately were:

• Changing Web login credentials: WebUI > User Settings > Change Password
• Changing Console credentials: `sudo passwd root`
• Change timezone: `cp /usr/share/zoneinfo/US/Eastern /etc/localtime`
• For fun: change to the dark theme: WebUI > User Settings > Theme

Get Monitoring!

Now that you’re setup, what are you waiting for, get started monitoring all the things! We won’t cover how to setup monitoring in this post, we’ll save that for a future post which delves deeper into the benefits and use-cases of Zabbix. Enjoy!
