Description: SLA metric type to be monitored. The rtt type is the round trip time of the probe packet. The jitter type is the inter-packet delay variance. The srcTodstTime type is the one-way trip time from source to destination. The dstTosrcTtime type is the one-way trip time from destination to source. The Mean Opinion Scores (MOS) type is derived only for udpJitterVoIP SLA. The Calculated Planning Impairment Factor (ICPIF) type is derived only for udpJitterVoIP SLA. ThepacketLoss type is to monitor loss of communication. The testCompletion type is for notifying about the completion of probe test. The sdJitterPos type is the source-to-destination positive jitter and the dsJitterPos type is the destination-to-source positivejitter.
