I want to monitory ESA devices on Zabbix. So I've configured snmp on ESA with snmpconfig command but Zabbix need a userID define so that it can pull all data not only icmp(ping). And there is no UserID settings defined/request during snmpconfig command. Therefore I just wonder if there is a way to define a user for snmp protocol? or is there a system predefine user for snmp ?
