Tutorial Zabbix – Monitor a TCP port
Now, we need to access the Zabbix server dashboard and add a new Host.
Open your browser and enter the IP address of your web server plus /zabbix.
In our example, the following URL was entered in the Browser:
• http://35.162.85.57/zabbix
On the login screen, use the default username and default password.
• Default Username: Admin
• Default Password: zabbix
After a successful login, you will be sent to the Zabbix Dashboard.
On the dashboard screen, access the Configuration menu and select the Host option.
On the top right of the screen, click on the Create host button.
On the Host configuration screen, you will have to enter the following information:
• Host Name – Enter a Hostname to monitor.
• Visible Hostname – Repeat the hostname.
• New group – Enter a name to identify a group of similar devices.
• Agent Interface – Enter the IP address of the Hostname.

Here is the new image with our configuration.
Click on the Add button to include this host on the Zabbix database.
On the dashboard screen, access the Configuration menu and select the Host option.
Locate and click on the hostname that you created before.
In our example, we selected the hostname: TECHEXPERT WEB SERVER
On the Host properties screen, access the Applications tab.

On the Host applications screen, create a new application named TCP Status.
After finishing the Application creation, access the Items tab.
