CISCO-ENTITY-PERFORMANCE-MIB: View SNMP OID List / Download MIB

This MIB module defines managed objects that facilitate to monitor performance of any physical entity, which are listed in the ENTITY-MIB (RFC 4133) entPhysicalTable. The performance monitoring includes utilization, input/output packet/byte rates, etc. This monitoring is through the measurement periods of current, 1-minute, 5-minutes, 15-minutes. The performance data calculation method would vary for each entity for a specific interval, hence users of this MIB should obtain the information using the object cepStatsAlgorithm for a specific interval. The performance statistics can be accumulated for the 1-minute, 5-minutes and 15-minutes (recommended) intervals. At any one time, an agent maintains one current (incomplete) interval for each interval type and up to 96 completed interval number. Fewer than 96 interval number of data will be available if the agent has been restarted within the last 24 hours for 15 minutes interval, 8 hours for 5 minutes interval, and 1.36 hours for 1 minute interval. There is no requirement for an agent to ensure fixed relationship between the start of a one/five/fifteen minute intervals and wall clock, however some agents may align the fifteen minutes interval with quarter hours. The following terminologies apply within the scope of this MIB. o entity - Any physical entity which can support performance monitoring as specified in this MIB o Utilization - The ratio of current usage to the maximum capacity the entity can handle o Input - Communication channel where packets arrive on the entity o Output - Communication channel where packets leave the entity Acronyms ======== SMA - Simple Moving Average

A notification indicating that the specific performance measurement is rising the configured threshold on this physical entity at a specific performance interval. This notification will be sent, whenever the cepStatsMeasurement is equal to or above the cepConfigRisingThreshold for a specific performance measurement at a specific interval and the notification control objects are enabled. An agent may throttle the generation of consecutive cepPerfThreshRisingEvent notification so that there is at least a five second (suggested default) gap between notification for an entity of specific performance measurement type at a specific interval.

A notification indicating that the specific performance measurement is falling the configured threshold on this physical entity at a specific performance interval. This notification will be sent, whenever the cepStatsMeasurement is equal to or below the cepConfigFallingThreshold for a specific performance measurement at a specific interval and the notification control objects are enabled. An agent may throttle the generation of consecutive cepPerfThreshFallingEvent notification so that there is at least a five second (suggested default) gap between notification for an entity of specific performance measurement type at a specific interval.

A notification indicating that the average throughput rate for the configured interval has exceeded the threshold or reached maximum bandwidth allowed. This notification will be sent, whenever the cepThroughputLevel object has the value warning(2) or exceed(3). The condition for trap generation will be checked in every cepThroughputInterval. cepThroughputNotif with ceqfpThrougputLevel as warning(2) indicates that average throughput rate has crossed the configured threshold. cepThroughputNotif with cepThrougputLevel as exceed(3) indicates that average throughput rate has reached maximum licensed bandwidth.

This object contains the rising threshold value for a specific performance measurement type at a specific performance time interval. The value of this object must be greater than cepConfigFallingThreshold. The supported range of this object can be identified by the object 'cepConfigPerfRange'. The value of zero indicates that no comparison is being made between the cepStatsMeasurement object value and the threshold value, therefore no event action will be generated.

This object contains the falling threshold value for a specific performance measurement type at a specific performance interval. The value of this object must be less than cepConfigRisingThreshold. The supported range of this object can be identified by the object 'cepConfigPerfRange'. The value of zero indicates that no comparison is being made between the cepStatsMeasurement object value and the threshold value, therefore no event action will be generated.

This object provides the control to the threshold notification for a specific entity performance type at a specific interval. The notification will be sent based on this object value and the global object 'cepThresholdNotifEnabled'. The following table would explain when the notification would be generated. cepThresholdNotifEnabled cepConfigThresholdNotifEnabled Notify ======================== ============================== ====== true true Yes true false No false true No false false No

This table maintains entity running performance, which are collected at various performance intervals.
