| filter | object | 返回紧缺匹配给定筛选条件的结果。 接受数组，数组的键为属性名，值为要匹配的一个值或者值数组。 支持附加筛选条件： host - 监控项所属主机的技术名称。 |
| limitSelects | integer | 限制子查询所返回的结果的数量。 应用到如下子查询： selectGraphs - 结果排序 name;selectTriggers - 结果排序 description. |
| sortfield | string/array | 根据给定的属性对结果排序。 可能的值是: itemid, name, key_, delay, history, trends, type and status. |
| countOutput | boolean | 在参考说明页面中详细描述了这些对于所有“get”方法都是通用的参数。 |
| editable | boolean | |
| excludeSearch | boolean | |
| limit | integer | |
