Add host

You have to had a host (= machine with a zabbix agent) on the server side in order to monitor it.


1. Go to the Configuration > Hosts > "Create host"

Zabbix add host


2. Now fill the following details of remote host

Zabbix add host - step 02
  • Hostname: Hostname of Remote system
  • Visible name: Name to be display in zabbix
  • Group: Select the desired group for you host
    • You should use Linux at least
    • You can create your own groups and classification as well
  • Agent interface: Fill the info of Zabbix agent running on host
    • Select the DNS option instead of IP. So if we move the client for any reason that will NOT impact the monitoring. :)
  • Status: Select initial status


IMPORTANT !! The name of the hostname must match the real hostname - as return by the `hostname` command !!


3. Set some monitoring templates to apply

Click on the "Templates" tab

Zabbix add host - step 03

To get the list of templates, just type template in the search area.

Don't forget to click the "ADD" button!

  • My custom vehco-smartcards includes the Zabbix agent template
  • The Linux OS includes the Zabbix agent template. :)


4. Automatic host inventory

  • Click on the "host inventory" tab
  • Enable the Automatic option.


5. Click "save" at the bottom of the page.




Network map

On the main screen you can create / manage maps and set their size using Edit button:

Network map

→ Configuration >> Maps


On the map, only put the main network elements = keys elements that are important to manage!

Ex: do not put the netboot clients, only the servers.
