7: Networking Accumulated Statistics A summary of all round trip time and any error conditions is displayed. The display will vary for non-jitter and jitter results. For example, non-jitter accumulated results will show: Latest Accumulated Statistics Probe 1/ICMP, operation icmp_190709_154501.dat: Operation Type: ICMP Echo to 172.19.100.17, Ethernet Port: both 10 packets sent 500 ms apart, timeout 200 ms Operation Start Time: 19/07/09 15:45:01.579 Last Packet RTT: 0.560 msec Round Trip Time Results: Number of RTT: 10 RTT Min/Avg/Max: 0.426/0.460/0.560 msec Number of Successes: 10 Number of Errors: 0 Lost Packet: 0 (0%) Out of Sequence: 0 Late Arrival: 0 Miscellaneous Error: 0 For jitter probes, positive (increasing latency) and negative (decreasing latency) statistics are shown, as well as the number of positive or negative jitter samples in each direction, and the sum and (and sum squared) of the positive or negative jitter times. These numbers give a summary of how much variation there was in latency times and if the variation was small or large.
