Zabbix¶

Zabbix ⧉ is how we monitor and alert for our Cluster and VMs. We self host a Zabbix server on a dedicated container

We have active Zabbix agents on our VMs

How to Install Zabbix¶

Make a Zabbix Directory /src/zabbix
Then download the repository to it
https://www.zabbix.com/download?zabbix=7.4&os_distribution=debian&os_version=12&components=agent_2&db=&ws= ⧉

How to Setup Zabbix on VM¶

Open the .conf file
sudo nano /etc/zabbix/zabbix_agent2.conf

Change the Hostname:
Hostname=vm_name.vm.cspp.ie

Restart the service and check its running
sudo systemctl restart zabbix-agent2
sudo systemctl status zabbix-agent2

How to connect Zabbix to Web Server¶

http://10.0.0.104/zabbix ⧉ (Password in the password manager)
Monitoring -> Hosts

Find Template host (It should be disabled)
Click Template -> Host -> Clone (Bottom Right)

Change:
Host name=vm_name.vm.cspp.ie
Visible name=Vm_name

`Interfaces`
	Type	IP address	DNS name	Connect to	Port
	Agent	vm_ip	vm_name.vm.cspp.ie	IP \| *DNS*	10050

Scroll down
Tick [ ] Enabled

Then Add.

Hover over "ZBX"
It should be green and say (Might take a minute):
Active checks Available
vm_name.vm.cspp.ie:10050 Available

Full Install and Setup of Zabbix (Clean VM)¶

Install¶

Make a Zabbix Directory /src/zabbix
Then download the repository to it
https://www.zabbix.com/download?zabbix=7.4&os_distribution=debian&os_version=12&components=agent_2&db=&ws= ⧉

Configuration¶

https://www.zabbix.com/documentation/7.4/en/manual/guides/monitor_linux ⧉

You need to open a port on UFW for the Zabbix CT to send passive requests
sudo ufw allow from 10.0.0.104 to any port 10050 proto tcp
(IP of the Zabbix Server and the port passive Zabbix uses)

sudo nano /etc/zabbix/zabbix_agent2.conf

Change the config to
Server=10.0.0.104
ServerActive=10.0.0.104
Hostname=vm_name.vm.cspp.ie

sudo systemctl restart zabbix-agent2

When creating the host on the web interface,
Host name=vm_name.vm.cspp.ie
Visible name=Vm_name

Templates:
Linux by Zabbix agent active
Docker by Zabbix agent 2
Systemd by Zabbix agent 2
Other templates should be added depending on what is running on the VM

Host groups=Virtual machines

Interfaces

Type	IP address	DNS name	Connect to	Port
Agent	vm_ip	vm_name.vm.cspp.ie	IP \| *DNS*	10050

If the Zabbix agent is getting Docker: Service is down, Zabbix needs to be given permissions to view the Docker Socket
sudo usermod -aG docker zabbix
sudo systemctl restart zabbix-agent2
