to database: • required - connect using TLS as transport mode without identity checks; • verify_ca - connect using TLS and verify certificate; 17 • verify_full - connect using TLS, verify certificate for best performance. Connection set up Zabbix supports two types of connect identifiers (connection methods): • Easy Connect • Net Service Name Connection configuration parameters for Zabbix server {DBUser/DBPassword[@<connect_identifier>]} <connect_identifier> can be specified either in the form of ”Net Service Name” or ”Easy Connect”. @[[//]Host[:Port]/ | ] Easy Connect Easy
