- IP address/DNS ( i.e : 10.182.45.23 / example.com)
- SNMP & version ( i.e: public & 1)

- Host Multiple tempates : Don't touch at this time
- Create Services linked to the template too : Don't touch at this time
- Check period : Choose delay between checks (i.e : 24x7 for all-time monitoring)
- Check command: Choose command to check host alive (you should put check_centreon_ping for a LAN configuration)
