rttMonHistoryCollectionBucketIndex
Round Trip Time Monitor History Collection Bucket Index
1.3.6.1.4.1.9.9.42.1.4.1.1.2
When the RttMonRttType is 'pathEcho', this uniquely defines a bucket for a given value of rttMonHistoryCollectionLifeIndex. For all other RttMonRttType this value will be the number of operations per a lifetime. Thus, this object increments on each operation attempt. For a particular value of rttMonHistoryCollectionLifeIndex, the agent assigns the first value of 1, the second value of 2, and so on. The sequence keeps incrementing until the number of buckets equals rttMonHistoryAdminNumBuckets, after which the most recent rttMonHistoryAdminNumBuckets buckets are retained (the index is incremented though).
