Output amperage alert

Hello,

I created an alert to notify me when my PDU exceeds the amperage limit. Looking at my alert in detail, I notice that my alert describes more than a hundred values.
Would it be possible to modify my alert to have only one value.

here is my alert :

SELECT * FROM devices,sensors WHERE (sensors.sensor_class = “current” && sensors.sensor_current > sensors.sensor_limit && devices.os = “apc”) = 1
