Retrieving filter conditions

Retrieve the name of the LLD rule “24681” and its filter conditions. The filter uses the “and” evaluation type, so the formula property is empty and eval_formula is generated automatically.

Request:

  1. {
  2.     "jsonrpc": "2.0",
  3.     "method": "discoveryrule.get",
  4.     "params": {
  5.         "output": [
  6.             "name"
  7.         ],
