Note
The MIB uses SNMP to retrieve the performance monitoring (PM) statistics on IP SLA.
The following table lists the PM data retrieved on IP SLA for jitter. To view the statistics, choose IP SLA

rttMonJitterStatsCompletions
The number of jitter operations that were successful.
rttMonJitterStatsOverThresholds
The number of jitter operations that violate the threshold.
rttMonJitterStatsNumOfRTT
The number of successful round trips.
rttMonJitterStatsRTTSum
The sum of the round-trip values.
rttMonJitterStatsRTTSum2Low
The sum of the squares of the low round-trip values.
rttMonJitterStatsRTTSum2High
The sum of the squares of the high round-trip values.
rttMonJitterStatsRTTMin

rttMonJitterStatsRTTMax
The maximum number of RTTs that were measured successfully.
rttMonJitterStatsMinOfPositivesSD
