use {HOST.NAME} for your DNS name of agent and snmp interaces. It will let your discovered host use visible name for your agent and snmp interface.

To use VMware simple checks the host must have the following user macros defined, after import these 3 templates, go to configuration > templates select Template Virt VMware > Macros
