I haven't error in log, so I don't understand why i just see one host in web Zabbix interface.


Thanks for help.

you need to add the host ( assuming you have not done as you see only one host )

Zabbix web interface offers both the configuration of monitoring and viewing Custom graphs can be created for a host or several hosts or for a single template.
