Tutorial – Zabbix Monitor Linux Process
Now, we need to access the Zabbix server dashboard and add the Linux computer as a 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.
