📓 Zabbix Simple Service Monitoring

(Written February 2026)

Abstract

A simple way to monitor your services in Zabbix, is to perform a periodic TCP Port Check.

Prerequisites

-

Zabbix TCP port check

My goal is to have a Zabbix dashboard where I can see which services are up, by checking if they are reachable on a certain port.

Step 1: Create an item

As I have a single host, that is running multiple services, I need to create an item for each service I wish to monitor. (If the services are on a host that has not been created, you need to create the host first).

In this example I want to check if the service Jellyfin is reachable.

Fill in the following:

• Name: name of your service
• Type: Simple check
• Key: net.tcp.service[http,,ThePortNumberOfYourService]
• Type of information: Numeric (unsigned)
• Host interface: leave this as is (should be the IP of your host)

You could if you want also tag your item:
