Hi, all! I want to monitor my APC ups. I use custom snmp lib, and there is OID, which can return one of the balues from 1 to 4. For this values ther are lookups (unknown(1),batteryNormal(2),batteryLow(3),batteryInFaultCondition(4)). How can i configure this sensor, to get allert, when value is not equal to "batteryNormal(2)', and warning when 'unknown(1)'?
