Cisco Entity Sensor Threshold Relation

1.3.6.1.4.1.9.9.91.1.2.1.1.3

This variable indicates the relation between sensor value (entSensorValue) and threshold value (entSensorThresholdValue), required to trigger the alarm. when evaluating the relation, entSensorValue is on the left of entSensorThresholdRelation, entSensorThresholdValue is on the right. in pseudo-code, the evaluation-alarm mechanism is: ... if (entSensorStatus == ok) then if (evaluate(entSensorValue, entSensorThresholdRelation, entSensorThresholdValue)) then if (entSensorThresholdNotificationEnable == true)) then raise_alarm(sensor's entPhysicalIndex); endif endif endif ... ::= { entSensorThresholdEntry 3 } SYNTAX SensorValue MAX-ACCESS read-write STATUS current DESCRIPTION This variable indicates the value of the threshold. To correctly display or interpret this variable's value, you must also know entSensorType, entSensorScale, and entSensorPrecision. However, you can directly compare entSensorValue with the threshold values given in entSensorThresholdTable without any semantic knowledge. ::= { entSensorThresholdEntry 4 } SYNTAX TruthValue MAX-ACCESS read-only STATUS current DESCRIPTION This variable indicates the result of the most recent evaluation of the threshold. If the threshold condition is true, entSensorThresholdEvaluation is true(1). If the threshold condition is false, entSensorThresholdEvaluation is false(2). Thresholds are evaluated at the rate indicated by entSensorValueUpdateRate. ::= { entSensorThresholdEntry 5 } SYNTAX TruthValue MAX-ACCESS read-write STATUS current DESCRIPTION This variable controls generation of entSensorThresholdNotification for this threshold. When this variable is 'true', generation of entSensorThresholdNotification is enabled for this threshold. When this variable is 'false', generation of entSensorThresholdNotification is disabled for this threshold. ::= { entSensorThresholdEntry 6 } -- -- Entity Sensor Global Objects -- SYNTAX TruthValue MAX-ACCESS read-write STATUS current DESCRIPTION This variable enables the generation of entSensorThresholdNotification globally on the device. If this object value is 'false', then no entSensorThresholdNotification will be generated on this device. If this object value is 'true', then whether a entSensorThresholdNotification for a threshold will be generated or not depends on the instance value of entSensorThresholdNotificationEnable for that threshold. ::= { entSensorGlobalObjects 1} -- -- notifications -- entitySensorMIBNotifications OBJECT IDENTIFIER ::= { entitySensorMIBNotificationPrefix 0 } entSensorThresholdNotification NOTIFICATION-TYPE OBJECTS { entSensorThresholdValue, entSensorValue } STATUS current DESCRIPTION The sensor value crossed the threshold listed in entSensorThresholdTable. This notification is generated once each time the sensor value crosses the threshold. The agent implementation guarantees prompt, timely evaluation of threshold and generation of this notification. ::= { entitySensorMIBNotifications 1 } -- -- conformance information -- entitySensorMIBCompliances OBJECT IDENTIFIER ::= { entitySensorMIBConformance 1 } entitySensorMIBGroups OBJECT IDENTIFIER ::= { entitySensorMIBConformance 2 } -- -- compliance statements -- entitySensorMIBComplianceV01 MODULE-COMPLIANCE STATUS deprecated DESCRIPTION An Entity-MIB implementation that lists sensors in its entPhysicalTable must implement this group.
