参数
(object/array) LLD规则用于create.
除了lld规则之外， 该方法还接受以下参数.
| 参数 | 数据类型 | 描述 |
|---|---|---|
| filter | object | LLD规则的lld-规则过滤器. |
| preprocessing | object/array | lld-规则预处理选项. |
| lld_macro_paths | object/array | LLD规则lld-宏路径选项. |
| overrides | object/array | lld-规则覆盖选项. |
返回值
(object) 返回一个包含所创建LLD规则ID的object， 这些ID存储在itemids属性下。返回的ID顺序与传入的LLD规则顺序一致。
示例
创建 LLD 规则
创建Zabbix agent LLD规则以发现已挂载的file系统. 被发现的监控项将每30秒更新一次.
