The value of tmnxOamPmCfgMeasIntvlsStored specifies the maximum number of historical measurement intervals which can be read using SNMP Get operations. For example, suppose tmnxOamPmCfgMeasIntvlsStored is 32 in the row indexed by {'mySess1', 'mi15Minutes(2)'}. Suppose 'mySess1' has a DMM test which has been running for at least 8 hours (i.e. 15 minutes/interval * 32 intervals). Then, the number of SNMP accessible 15 minute intervals for the test is shown in the following table. Test State Number of SNMP Accessible 15 Minute Intervals running 33 (i.e. 32 historical intervals, and the current interval) stopped 32 (i.e. 32 historical intervals) At the moment when a test is stopped, the current interval becomes the newest historical interval. If that makes the total number of historical intervals larger than tmnxOamPmCfgMeasIntvlsStored, the oldest historical interval is made SNMP inaccessible. In a typical configuration, older statistics are recorded in a local file (see tmnxOamPmCfgMeasIntvlAccntPolicy). Statistics in the file are not SNMP accessible. The range and default of tmnxOamPmCfgMeasIntvlsStored varies with the row's measurement interval duration index value, as follows. tmnxOamPmCfgMeasIntvlDuration Intvls Stored Range Intvls Stored Default 'mi5Minutes(5)' 1..96 32 'mi15Minutes(2)' 1..96 32 'mi1Hour(3)' 1..24 8 'mi1Day(4)' 1..1 1 The following limit is enforced per session (where 'S' is the session name): tmnxOamPmCfgMeasIntvlsStored.S.mi5Minutes(5) + tmnxOamPmCfgMeasIntvlsStored.S.mi15Minutes(2) <= 96.
