Adding entities to a template

Adding an item or any other entity to a template is virtually identical to the same operation performed on a regular host. This is especially true for items. As you already know, item keys are the basic building blocks of the Zabbix monitoring pipeline, and you don't have to specify any kind of address or interface when you create them as Zabbix will take this kind of information from the host the item is assigned to.
