| ciscoEntitySensorExtMIB | 1.3.6.1.4.1.9.9.745 | | | This MIB is extension to ENTITY-SENSOR-MIB(RFC 3433). This MIB
also defines the notifications applicable for sensors reported
in ENTITY-MIB(RFC 4133). |
| ciscoEntitySensorExtMIBNotifs | 1.3.6.1.4.1.9.9.745.0 | | | |
| NTF ceSensorExtThresholdNotification | 1.3.6.1.4.1.9.9.745.0.1 | | | This notification is generated once each time
the sensor value crosses the threshold value
specified by ceSensorExtThresholdValue object. |
| ciscoEntitySensorExtMIBObjects | 1.3.6.1.4.1.9.9.745.1 | | | |
| ceSensorExtThresholdTable | 1.3.6.1.4.1.9.9.745.1.1 | | not-accessible | This table lists the threshold severity, relation, and
comparison value, for a sensor entity listed in
entPhysicalTable. |
| ceSensorExtThresholdEntry | 1.3.6.1.4.1.9.9.745.1.1.1 | | not-accessible | An ceSensorExtThresholdTable entry describes the
thresholds for a sensor: the threshold severity,
the threshold value, the relation, and the
evaluation of the threshold.
Only entities with entPhysicalClass 'sensor'
are listed in this table.
For non FRU entities the entries are created by the agent at
system startup and entries are never deleted by the agent.
For FRU entities the entries are created at system startup
if FRU is inserted at system startup, else entries are created
when FRU is inserted. Entries are deleted by the agent when
FRU is removed. |
| U32 ceSensorExtThresholdIndex | 1.3.6.1.4.1.9.9.745.1.1.1.1 | Unsigned32 | not-accessible | An index that uniquely identifies an entry
in the ceSensorExtThresholdTable. This index
permits the same sensor to have several
different thresholds. |
| CIS ceSensorExtThresholdSeverity | 1.3.6.1.4.1.9.9.745.1.1.1.2 | CiscoSensorThresholdSeverity | read-write | This object specifies the severity of this threshold. |
| CIS ceSensorExtThresholdRelation | 1.3.6.1.4.1.9.9.745.1.1.1.3 | CiscoSensorThresholdRelation | read-write | This object specifies the boolean relation between
sensor value (entPhySensorValue) and threshold value
(ceSensorExtThresholdValue), required to
trigger the alarm.
in pseudo-code, the evaluation-alarm mechanism is:
...
if (evaluate(entPhySensorValue,
ceSensorExtThresholdRelation,
ceSensorExtThresholdValue))
then
if (((ceSensorExtThresholdNotifEnable
== enabled) ||
(ceSensorExtThresholdNotifEnable
== transparent)) &&
(ceSensorExtThresholdNotifGlobalEnable
== enabled))
then
raise_alarm(sensor's entPhysicalIndex);
endif
endif
... |
| ENT ceSensorExtThresholdValue | 1.3.6.1.4.1.9.9.745.1.1.1.4 | EntitySensorValue | read-write | This object specifies the value of the threshold.
The value of objects entPhySensorType, entPhysSensorScale
and entPhySensorPrecision for this sensor entity defines
how ceSensorExtThresholdValue can be displayed or
intepreted by the user.
entPhySensorValue can be compared with
ceSensorExtThresholdValue without taking
care of semantics of both objects. |
| T/F ceSensorExtThresholdEvaluation | 1.3.6.1.4.1.9.9.745.1.1.1.5 | TruthValue | read-only | This object indicates the result of the most
recent evaluation of the threshold.
The agent will execute the below 'evaluate' function
to generate the notification. 'evaluate' function
returns a boolean value.
evaluate(entPhySensorValue,
ceSensorExtThresholdRelation,
ceSensorExtThresholdValue)
If evalute function returns true then
ceSensorExtThresholdEvaluation is set to 'true'
If evaluate function returns false then
ceSensorExtThresholdEvaluation is set to 'false'.
Thresholds are evaluated at the rate indicated by
entPhySensorValueUpdateRate. |
| INT ceSensorExtThresholdNotifEnable | 1.3.6.1.4.1.9.9.745.1.1.1.6 | INTEGER | read-write | A control object to activate/deactivate
ceSensorExtThresholdNotification.
This object should hold any of the below values.
enabled(1) - The notification is enabled for this entity
disabled(2) - The notification is disabled for this entity
transparent(3)- The notification is enabled/disabled based on
ceSensorExtThresholdNotifGlobalEnable
object
This object controls generation of
ceSensorExtThresholdNotification for this threshold.
An exception to this is, if this object is set to 'transparent'
then ceSensorExtThresholdNotification for this threshold
is controlled by ceSensorExtThresholdNotifGlobalEnable
object.
This truth table explains how
ceSensorExtThresholdNotifEnable is related with
ceSensorExtThresholdNotifGlobalEnable to control the
ceSensorExtThresholdNotification for this threshold
E = enabled, D = Disabled, T = Transparent
local_flag = ceSensorExtThresholdNotifEnable
global_flag = ceSensorExtThresholdNotifGlobalEnable

| INT ceSensorExtThresholdNotifGlobalEnable | 1.3.6.1.4.1.9.9.745.1.2.1 | INTEGER | read-write | A control object to activate/deactivate
ceSensorExtThresholdNotification.
This object should hold any of the below values.
enabled(1) - The notification is enabled globally
on the device
disabled(2)- The notification is disabled globally
on the device
This object enables the generation of
ceSensorExtThresholdNotification globally
on the device. If this object value is
'disabled', then no ceSensorExtThresholdNotification
will be generated on this device. If this object
value is 'enabled', then whether a
ceSensorExtThresholdNotification for a threshold will
be generated or not depends on the instance value of
ceSensorExtThresholdNotifEnable for that
threshold. |
