The value of tmnxOamPmStsMeasIntvlIndexNewest indicates the interval number of the newest interval for the specified session, test type (e.g. 'dmm(1)'), and interval duration (e.g. 'mi15Minutes(2)'). This value is provided as the tmnxOamPmStsIntvlNum index value when reading a row for the newest interval in an OAM-PM statistics table. For a running test, the newest interval is the current interval. For a stopped test, the newest interval is the most recent historical interval. A stopped test does not have a current interval. The interval number of the oldest interval for the specified session, test type, and interval duration can be computed from this value. For a running test, the formula is interval_number_of_the_oldest_interval = MAX(tmnxOamPmStsMeasIntvlIndexNewest-tmnxOamPmCfgMeasIntvlsStored, 1). For a stopped test, the formula is interval_number_of_the_oldest_interval = MAX(tmnxOamPmStsMeasIntvlIndexNewest-tmnxOamPmCfgMeasIntvlsStored+1,1).
