Monitoring TrueNAS with Zabbix and Displaying Graphics with Grafana

The last day I read that someone was needing some help about how to monitor a TrueNAS using Zabbix, and why not displaying graphics in Grafana. Below I will show a few simple steps for accomplishing it.

This was tested in the following environment:

• Zabbix 5.0 LTS on Linux CentOS 8 Stream
• Grafana OSS on Linux CentOS 8 Stream
• TrueNAS Core version TrueNAS-12.0-U2.1

I assume you have a Zabbix server running, in case you might not, here you will find the instructions for installing Zabbix 5.0 LTS on Linux CentOS 8

In case you need to install Grafana, check the following steps:

Create the following repo file with nano /etc/yum.repo.d/grafana.repo and add the following content:

[grafana]

name=grafana

baseurl=https://packages.grafana.com/oss/rpm

repo_gpgcheck=1

enabled=1

gpgcheck=1

gpgkey=https://packages.grafana.com/gpg.key

sslverify=1

sslcacert=/etc/pki/tls/certs/ca-bundle.crt

Now you can proceed to install Grafana with the following command:

dnf install -y grafana

Now enable and start the service as well:

systemctl enable grafana-server && systemctl start grafana-server

Find more information about Grafana OSS releases installation, check the following link: Grafana Information

If you haven't made the integration yet of Grafana with Zabbix, please follow this procedure: Grafana and Zabbix Integration

There is a template you could use for monitoring your TrueNAS, BUT before uploading FreeNAS-11 Zabbix Template, you need to upload the following templates:

SNMP Interface Discovery

SNMP Processors Discovery

SNMP Generic

Now you can upload the FreeNAS-11 Zabbix template in order to monitor your TrueNAS:
