OID list for memory threshold
- health Threshold Device Memory Limit
- healthThreshDeviceMemoryLimit 1.3.6.1.4.1.800.2.18.6.5 (defined in XYLAN-HEALTH-MIB)
Device memory threshold value. Units are percent. Default is 80. - IBM APPN Memory Warning Threshold
- ibmappnMemoryWarnThresh 1.3.6.1.4.1.2.6.2.13.1.7.3 (defined in rfc1593)
Allocation threshold beyond which storage management considers the storage resources to be constrained. - IBM APPN Memory Critical Threshold
- ibmappnMemoryCritThresh 1.3.6.1.4.1.2.6.2.13.1.7.4 (defined in rfc1593)
Allocation threshold beyond which storage management considers the storage resources to be critically constrained. - Compaq Server Health Correct Memory Error Count Threshold
- cpqHeCorrMemErrorCntThresh 1.3.6.1.4.1.232.6.2.3.5 (defined in CPQHLTH)
The error threshold for Correctable memory errors. When cpqHeCorrMemErrCount is greater than or equal to this value user action is required to replace the failing memory module. - shared Memory Rm If Threshold Configuration Table
- sharedMemRmIfThresholdCfgTable 1.3.6.1.4.1.9.10.10.1.6.2 (defined in CISCO-ATM-RM-MIB)
The (conceptual) table containing the output queue thresholds used on ATM physical interface output queues. These are specified per Service Category. This table is not instantiated for interfaces to which it cannot be applied. - shared Memory Rm If Threshold Configuration Entry
- sharedMemRmIfThresholdCfgEntry 1.3.6.1.4.1.9.10.10.1.6.2.1 (defined in CISCO-ATM-RM-MIB)
An entry (conceptual row) in the sharedMemRmIfThresholdCfgTable containing Resource Management configuration for an ATM interface. A particular row is identified by the value of MIB-II's ifIndex, and the Service Category. - shared Memory Rm If Discard Threshold
- sharedMemRmIfDiscardThreshold 1.3.6.1.4.1.9.10.10.1.6.2.1.1 (defined in CISCO-ATM-RM-MIB)
The output queue CLP/EPD threshold for this Service Category on this ATM interface. This is expressed in percent-of-full. Note that 100% full effectively turns off the threshold. - shared Memory Rm If Efci Threshold
- sharedMemRmIfEfciThreshold 1.3.6.1.4.1.9.10.10.1.6.2.1.2 (defined in CISCO-ATM-RM-MIB)
The output queue EFCI marking threshold for this Service Category on this ATM interface. This is expressed in percent-of-full. Note that 100% full effectively turns off the threshold. - shared Memory Rm If Abr Relative Rate Threshold
- sharedMemRmIfAbrRelativeRateThreshold 1.3.6.1.4.1.9.10.10.1.6.2.1.3 (defined in CISCO-ATM-RM-MIB)
The ABR Relative-rate marking queue congestion threshold for the ABR queue on this ATM interface. This is expressed in percent-of-full. Note that 100% full effectively turns off the threshold. This object is only defined for the abr service category. - Cisco Enhanced Memory Buffer Cache Threshold
- cempMemBufferCacheThreshold 1.3.6.1.4.1.9.9.221.1.1.3.1.6 (defined in CISCO-ENHANCED-MEMPOOL-MIB)
Indicates the threshold limit for number of cache buffers used(cempMemBufferCacheUsed). - Cisco Enhanced Memory Buffer Cache Threshold Count
- cempMemBufferCacheThresholdCount 1.3.6.1.4.1.9.9.221.1.1.3.1.7 (defined in CISCO-ENHANCED-MEMPOOL-MIB)
Indicates how many times the number of cache buffers used(cempMemBufferCacheUsed) has crossed the threshold value(cempMemBufferCacheThreshold). - Cisco Entity Quantum Flow Processors Memory Resource Rising Threshold
- ceqfpMemoryResRisingThreshold 1.3.6.1.4.1.9.9.715.1.1.7.1.6 (defined in CISCO-ENTITY-QFP-MIB)
This object represents the rising threshold value for this memory resource. A value of zero means that the rising threshold is not supported for this memory resource. The value of this object can not be set to lower than or equal to ceqfpMemoryResFallingThreshold. A rising (ceqfpMemoryResRisingThreshNotif) notification will be generated, whenever the memory resource usage (ceqfpMemoryResInUse) is equal to or greater than this value. After a rising notification is generated, another such notification will not be generated until the ceqfpMemoryResInUse falls below this value and reaches the ceqfpMemoryResFallingThreshold. - Cisco Entity Quantum Flow Processors Memory Resource Falling Threshold
- ceqfpMemoryResFallingThreshold 1.3.6.1.4.1.9.9.715.1.1.7.1.7 (defined in CISCO-ENTITY-QFP-MIB)
This object represents the falling threshold value for this memory resource. A value of zero means that the falling threshold is not supported for this memory resource. The value of this object can not be set to higher than or equal to ceqfpMemoryResRisingThreshold. A falling (ceqfpMemoryResRisingThreshNotif) notification will be generated, whenever the memory resource usage (ceqfpMemoryResInUse) is equal to or lesser than this value. After a falling notification is generated, another such notification will not be generated until the ceqfpMemoryResInUse rises above this value and reaches the ceqfpMemoryResRisingThreshold. - Cisco Ggsn Memory Threshold
- cGgsnMemoryThreshold 1.3.6.1.4.1.9.9.240.1.3.11 (defined in CISCO-GGSN-MIB)
GGSN memory overload protection is a mechanism to prevent GGSN from completely running out of memory when GGSN is running near its capacity or in some failure scenarios like CG down. A protection mechanism was put into place where charging triggers would be ignored, PDP create would be rejected, PDP update request will delete PDP, once the available memory on the GGSN drops below a configured threshold. Charging triggers occurs due to certain criteria's like volume limit, time limit. When one of the conditions is met , the CDR's are closed and will be updated to the charging gateway.
