Scalar and Boolean class Variables

Device variables can be classified in terms of the way they represent their data. Scalar variables are those

values that are represented by a range of possible numbers. Devices that monitor temperature or humidity

are classified as scalar. Boolean variables define only two states: binary one or zero. Devices that monitor

power (PWR FAIL/PWR OK), flooding (WET/DRY), or control a relay position (ON/OFF) are classified

as Boolean.

The distinction between scalar and Boolean is important because it influences the way data is retrieved

from the Sensorsoft SNMP Agent. If you examine the MIB, you will notice objects prefixed with Scalar or

Boolean. Only one set of variables is of interest to you, depending on the type of SSD being used. When

using a Scalar SSD the values of the MIB objects prefixed with or containing Scalar are used and those

prefixed with or containing Boolean are not used. When using a Boolean SSD, the values of the MIB

objects prefixed with or containing Boolean are used and those prefixed with or containing Scalar are not

used. Refer to section Description of Alert MIB Objects section for a more detailed description of each MIB

object.

Sensorsoft Alert MIB

The typical way to manipulate the Sensorsoft Alert SNMP Agent’s variables is to load the provided MIB

into a third party, Network Management Software (NMS) that can act as an interface between the user and

the Sensorsoft Alert SNMP Agent.

The Sensorsoft Alert MIB file can be downloaded from:

http://www.sensorsoft.com/download/alertmib1.mib

You should load the MIB into your NMS as per the procedure recommended by the manufacturer. You

may refer to section Description of Alert MIB Objects for a complete list of objects in the Sensorsoft Alert

MIB.
