### 返回值

`(object)` Returns an object containing the IDs of the created item
prototypes under the `itemids` property. The order of the returned IDs
matches the order of the passed item prototypes. `(object)`

#### Creating an item prototype

Create an item prototype to monitor free disc space on a discovered file
system. Discovered items should be numeric Zabbix agent items updated
every 30 seconds. 创建一个item
prototype去监控自动发现的文件系统上的磁盘空间。Discovered items
应该每30秒更新数字化的Zabbix agent监控项。

#### Creating an item prototype with preprocessing

#### 创建一个预处理的 item prototype

Create an item using change per second and a custom multiplier as a
second step. 创建一个使用每秒变化并带有自定义乘法器作为第二部的监控项。

#### Creating dependent item prototype

#### 创建依赖item prototype

Create Dependent item prototype for Master item prototype with ID 44211.
Only dependencies on same host (template/discovery rule) are allowed,
therefore Master and Dependent item should have same hostid and ruleid.
为ID为44211的主item prototype创建一个依赖item
prototype。只有在同一个主机的(template/discovery
rule)依赖才可以被接受，因此主 item prototype 和依赖 item prototype
应该拥有相同的hostid和ruleid。
