创建

说明

object discoveryrule.create(object/array lldRules)

此方法允许创建新的LLD规则。

参数

(object/array) 要创建的LLD规则。

除了标准LLD规则属性之外,该方法还接受以下参数。

属性 类 描述
filter object LLD规则LLD规则的过滤对象
preprocessing array LLD规则预处理选项
lld_macro_paths array LLD规则预处理选项
overrides array LLD规则覆盖选项

返回值

(object)itemids属性下返回一个包含IDs的被创建的LLD规则。返回的IDs的顺序与传递的LLD规则顺序相匹配。

示例

新建LLD规则

创建Zabbix agent LLD规则去发现以已装入的文件系统。发现监控项(items)将被每30s被更新一次。

           "jsonrpc": "2.0",
           "method": "discoveryrule.create",

               ]
           },
           "id": 1
       }

使用一个过滤器

创建有由一套删选条件的得到的LLD规则。这些条件将使用逻辑“和”运算符将条件组合在一起。

请求:

{
           "jsonrpc": "2.0",
           "method": "discoveryrule.create",
           "params": {

                   "evaltype": 1,
                   "conditions": [
                       {
                           "macro": "{#MACRO1}",
                           "value": "@regex1"
                       },
                       {
                           "macro": "{#MACRO2}",
                           "value": "@regex2"
                       },
                       {
                           "macro": "{#MACRO3}",
                           "value": "@regex3"
                       }
                   ]
               }
           },
           "auth": "038e1d7b1735c6a5436ee9eae095879e",

       }

响应:

{
           "jsonrpc": "2.0",
           "result": {
               "itemids": [
                   "27665"
               ]
           },
           "id": 1
       }

使用自定义表达式的筛选器

创建一个带有过滤器的LLD规则,该过滤器将使用自定义表达式来计算条件。LLD规则必须只发现“{#MACRO1}”宏值同时匹配正则表达式“regex1”和“regex2”的对象,“{#MACRO2}”宏值同时匹配“regex3”或“regex4”的对象。公式id“A”、“B”、“C”和“D”是任意选择的。
