对对对 ，太需要了！！！
# 状态值映射
- ifOperStatus=ifOperStatusRaw@map(1=up,2=down)
还有@where和@count()函数等：
calculates:
# 直接使用字符串过滤统计
- total_devices=status_list@where(status_list!="Empty")@count()
- connected_devices=status_list@where(status_list=="Connected")@count()
-
disconnected_devices=status_list@where(status_list=="Unconnect")@count()
- empty_devices=status_list@where(status_list=="Empty")@count()
