(object/array) LLD rules to create.

Additionally to the standard LLD rule properties, the method accepts the following parameters.

Parameter Type Description
filter object LLD rule filter object for the LLD rule.

Return values

(object) Returns an object containing the IDs of the created LLD rules under the itemids property. The order of the returned IDs matches the order of the passed LLD rules.

Examples

Creating an LLD rule

Create a Zabbix agent LLD rule to discover mounted file systems. Discovered items will be updated every 30 seconds.

Using a filter

Create an LLD rule with a set of conditions to filter the results by. The conditions will be grouped together using the logical "and" operator.

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

                       {
                           "macro": "{#MACRO1}",
                           "value": "@regex1"
                       },
                       {
                           "macro": "{#MACRO2}",
                           "value": "@regex2"
                       },
                       {
                           "macro": "{#MACRO3}",
                           "value": "@regex3"
                       }
                   ]
               }
           },

Response:

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

Using a custom expression filter

Create an LLD rule with a filter that will use a custom expression to evaluate the conditions. The LLD rule must only discover objects the "{#MACRO1}" macro value of which matches both regular expression "regex1" and "regex2", and the value of "{#MACRO2}" matches either "regex3" or "regex4". The formula IDs "A", "B", "C" and "D" have been chosen arbitrarily.
