ARISTA-ENTITY-SENSOR-MIB

2014-08-15

This MIB module augments the entPhySensorTable of ENTITY-SENSOR-MIB to provide threshold information for various sensors in the system. For example, a given device may have several voltage sensors as well as temperature sensors each with appropriate threshold support to help NMS systems detect and alert appropriately. In addition, on systems where it is supported, if the sensor value crosses the supported threshold value the system can generate appropriate notification as well.

entPhysicalIndex

PhysicalIndexAn arbitrary value that uniquely identifies the physical entity. The value should be a small positive integer. Index values for different physical entities are not necessarily contiguous. (1..2147483647) · Integer32 · hint d

The index for this entry.

EntitySensorValueAn object using this data type represents an Entity Sensor value. An object of this type SHOULD be defined together with objects of type EntitySensorDataType, EntitySensorDataScale and EntitySensorPrecision. Together, associated objects of those three types are used to identify the semantics of an object of this data type. The semantics of an object using this data type are determined by the value of the associated EntitySensorDataType object. If the associated EntitySensorDataType object is equal to 'voltsAC(3)', 'voltsDC(4)', 'amperes(5)', 'watts(6), 'hertz(7)', 'celsius(8)', or 'cmm(11)', then an object of this type MUST contain a fixed point number ranging from -999,999,999 to +999,999,999. The value -1000000000 indicates an underflow error. The value +1000000000 indicates an overflow error. The EntitySensorPrecision indicates how many fractional digits are represented in the associated EntitySensorValue object. If the associated EntitySensorDataType object is equal to 'percentRH(9)', then an object of this type MUST contain a number ranging from 0 to 100. If the associated EntitySensorDataType object is equal to 'rpm(10)', then an object of this type MUST contain a number ranging from -999,999,999 to +999,999,999. If the associated EntitySensorDataType object is equal to 'truthvalue(12)', then an object of this type MUST contain either the value 'true(1)' or the value 'false(2)'. If the associated EntitySensorDataType object is equal to 'other(1)' or unknown(2)', then an object of this type MUST contain a number ranging from -1000000000 to 1000000000. (-1000000000..1000000000) · Integer32

The low thresold value for the given sensor at which point the entity's alarm status is set to warning.

aristaEntSensorThresholdLowCritical

1.3.6.1.4.1.30065.3.12.1.1.1.2

The low critical value for the given sensor at which point the entity's alarm status is set to critical.

aristaEntSensorThresholdHighWarning

1.3.6.1.4.1.30065.3.12.1.1.1.3

The high thresold value for the given sensor at which point the entity's alarm status is set to warning.

aristaEntSensorThresholdHighCritical

1.3.6.1.4.1.30065.3.12.1.1.1.4

The high critical value for the given sensor at which point the entity's alarm status is set to critical.

aristaEntSensorStatusDescr

1.3.6.1.4.1.30065.3.12.1.1.1.5

SnmpAdminStringAn octet string containing administrative information, preferably in human-readable form. To facilitate internationalization, this information is represented using the ISO/IEC IS 10646-1 character set, encoded as an octet string using the UTF-8 transformation format described in [RFC2279]. Since additional code points are added by amendments to the 10646 standard from time to time, implementations must be prepared to encounter any code point from 0x00000000 to 0x7fffffff. Byte sequences that do not correspond to the valid UTF-8 encoding of a code point or are outside this range are prohibited. The use of control codes should be avoided. When it is necessary to represent a newline, the control code sequence CR LF should be used. The use of leading or trailing white space should be avoided. For code points not directly supported by user interface hardware or software, an alternative means of entry and display, such as hexadecimal, may be provided. For information encoded in 7-bit US-ASCII, the UTF-8 encoding is identical to the US-ASCII encoding. UTF-8 may require multiple bytes to represent a single character / code point; thus the length of this object in octets may be different from the number of characters encoded. Similarly, size constraints refer to the number of encoded octets, not the number of characters represented by an encoding. Note that when this TC is used for an object that is used or envisioned to be used as an index, then a SIZE restriction MUST be specified so that the number of sub-identifiers for any object instance does not exceed the limit of 128, as defined by [RFC3416]. Note that the size of an SnmpAdminString object is measured in octets, not characters. SIZE (0..255) · OCTET STRING · hint 255t

A textual description of the current status of the sensor. It serves as a human-readable representation of the operating status including any threshold alerts.

Trap details

aristaEntSensorAlarm

1.3.6.1.4.1.30065.3.12.0.1

This notification is generated under 2 conditions: a) When the value of the sensor value crosses a supported low or high threshold into warning or critical status. b) If previously the sensor value was in a warning or critical status but returns back to a normal status.

entPhysicalDescr

1.3.6.1.2.1.47.1.1.1.1.2

A textual description of physical entity. This object should contain a string that identifies the manufacturer's name for the physical entity and should be set to a distinct value for each version or model of the physical entity.

entPhySensorValue

1.3.6.1.2.1.99.1.1.1.4

The most recent measurement obtained by the agent for this sensor. To correctly interpret the value of this object, the associated entPhySensorType, entPhySensorScale, and entPhySensorPrecision objects must also be examined.

entStateAlarm

1.3.6.1.2.1.131.1.1.1.5

EntityAlarmStatusRepresents the possible values of alarm status. An Alarm [RFC3877] is a persistent indication of an error or warning condition. When no bits of this attribute are set, then no active alarms are known against this entity and it is not under repair. When the 'value of underRepair' is set, the resource is currently being repaired, which, depending on the implementation, may make the other values in this bit string not meaningful. When the value of 'critical' is set, one or more critical alarms are active against the resource. When the value of 'major' is set, one or more major alarms are active against the resource. When the value of 'minor' is set, one or more minor alarms are active against the resource. When the value of 'warning' is set, one or more warning alarms are active against the resource. When the value of 'indeterminate' is set, one or more alarms of whose perceived severity cannot be determined are active against this resource. A value of 'unknown' means that this resource is unable to report alarm state. · BITS

The alarm status for this entity. It does not include the alarms raised on child components within its containment hierarchy. A value of 'unknown' means that this entity is unable to report alarm state. Note that this differs from 'indeterminate', which means that alarm state is supported and there are alarms against this entity, but the severity of some of the alarms is not known. If no bits are set, then this entity supports reporting of alarms, but there are currently no active alarms against this entity.
