What's installed on your Zabbix server?
- Zabbix 7.0 LTS server and web interface, from the official Docker images
- PostgreSQL 16 database
- Zabbix Agent 2, with a host named Zabbix server that monitors the machine itself
- An account named Admin, whose default password is changed during install, with the new one in your panel
- Istanbul time zone on the server and web interface
- HTTPS through Caddy on an sslip.io address based on your IP, so a domain is optional
- Firewall with only ports 22, 80 and 443 open, keeping Zabbix's port 10051 closed to the outside
What size do you need for Zabbix?
The Zabbix 7.0 documentation gives example hardware by metric count: 2 cores and 8 GB of RAM for 1,000 metrics, 4 cores and 16 GB for 10,000, and 16 cores and 64 GB for 100,000. Its rough estimate is that 1 metric equals 1 item, 1 trigger and 1 graph. To try it out or watch a few servers, a rule-of-thumb start is 4 GB, moving to 8 GB as you near 1,000 metrics. Disk use depends on the metric count and how long you keep history.
| Use | Size | Price | Choose |
|---|---|---|---|
| A few people | 4 GB RAM · 2 vCore · 60 GB NVMe | $6.89/mo | |
| Small team | 8 GB RAM · 4 vCore · 120 GB NVMe | $13.62/mo | |
| Company | 16 GB RAM · 8 vCore · 200 GB NVMe | $25.15/mo |
Who is it for?
- Anyone wanting CPU, memory and disk status for several servers on one screen
- IT teams monitoring switches, routers and printers over SNMP
- Businesses that want an email alert when something goes wrong
- Companies keeping their monitoring data on their own server
What happens after you order?
- Set the size and complete your payment.
- Your server starts and Zabbix installs itself. The first start can take a little longer, so wait for the App row to say Zabbix is ready.
- On the Overview tab, click Open app. The login is Admin with a capital A, and the password is in the Password row.
- Under Monitoring > Hosts, check that the Zabbix server host is collecting data.
- Install Zabbix Agent on the server you want to watch, then add it under Data collection > Hosts and pick a template.
- Set up email under Alerts > Media types, and add an alert address to your user.
With every server
- Daily backups included in the price
- Unlimited traffic
- Full root access
- Scale RAM and CPU up or down later, and grow the disk
- Location: Istanbul · IST-1.
Good to know
- Zabbix's port 10051 is closed to the outside, so agents run in passive mode: Zabbix connects to port 10050 on each monitored server. On that server, open the port to your Zabbix server's IP address.
- Outgoing email isn't set up. For alerts, enter your own SMTP service under Alerts > Media types, where Gmail and Office365 have ready-made options. The service isn't included in the price.
- Since version 7.0, Zabbix is licensed under AGPLv3, with no usage fee. If you modify the code and offer it to others, you have to share your changes. The maker's paid technical support isn't included in the price.
- Full support for 7.0 LTS runs until 30 June 2027, and limited support until 30 June 2029. The install doesn't move to the next LTS version by itself.
- Updates are your responsibility. In /opt/seturack/zabbix, docker compose pull and docker compose up -d fetch the newest release on the 7.0 branch.
- The interface starts in English. Your panel keeps showing the install password, so if you change it, keep the new one safe yourself.
Zabbix questions and answers
How much RAM does Zabbix need?
The official documentation lists 2 cores and 8 GB of RAM for 1,000 metrics, and 4 cores and 16 GB for 10,000. To try it out or watch a few servers, a rule-of-thumb start is 4 GB, and you can scale up from your panel as metrics grow.
How many servers can Zabbix monitor?
The official table is based on metrics rather than servers, so there's no fixed server count. The template you pick decides how many metrics each server produces, and the active metric count and polling intervals decide what you need.
How do I add a server to Zabbix?
Install Zabbix Agent on the server you want to watch, put your Zabbix server's IP address in its Server setting, and open port 10050 to that address. Then add the server under Data collection > Hosts and pick a template.
Can I use active agents or zabbix_sender?
Not directly, because port 10051 is closed to the outside in this install. You have root access, though: add port 10051 to the zabbix-server service in compose.yaml and run docker compose up -d, and active mode becomes available.
Can Zabbix monitor network devices?
Yes. Zabbix monitors devices such as printers, switches, routers and UPS units over SNMP. SNMP requests go from the Zabbix server to the device over UDP, so the device has to be reachable from the internet or through a VPN you set up.
How do I connect my own domain to Zabbix?
Point the A record at your server's IP address and add the name to the Caddy settings. Zabbix needs no separate address setting. Nothing changes for your agents either, because the Zabbix server starts those connections.
