| filter | object | 仅返回完全匹配指定过滤条件的结果. 接受一个object，其中键是属性名，值是要匹配的单个值或array. 不支持 text 数据类型属性.支持附加属性: host - 监控项所属主机的技术名称. |
| limitSelects | integer | 限制子查询返回的记录数. 适用于以下子查询: selectGraphs - 结果将按name排序;selectTriggers - 结果将按description排序. |
| sortfield | string/array | 按指定属性排序结果. 可能值: itemid, name, key_, delay, history, trends, type, status. |
| countOutput | boolean | 这些参数在通用get方法参数中描述. |
| editable | boolean | |
