Show IP SLA statistics output definitions

Question

Does anyone have a link or documentation that defines ALL the fields in a show ip sla statistics command? Some are clearly obvious, but in Packet Loss Values for instance what are the measurement values for Source to Destination Loss Periods Number: or Source to Destination Loss Periods Number: ?
IPSLA operation id: 8502

Type of operation: udp-jitter
Voice Scores:
        MinOfICPIF: 0   MaxOfICPIF: 0   MinOfMOS: 0     MaxOfMOS: 0
RTT Values:
        Number Of RTT: 48157            RTT Min/Avg/Max: 54/56/503 milliseconds
Latency one-way time:
        Number of Latency one-way Samples: 0
        Source to Destination Latency one way Min/Avg/Max: 0/0/0 milliseconds
        Destination to Source Latency one way Min/Avg/Max: 0/0/0 milliseconds
Jitter Time:
        Number of SD Jitter Samples: 43824
        Number of DS Jitter Samples: 43824
        Source to Destination Jitter Min/Avg/Max: 0/1/142 milliseconds
        Destination to Source Jitter Min/Avg/Max: 0/1/81 milliseconds
Packet Loss Values:
        Loss Source to Destination: 96 
        Source to Destination Loss Periods Number: 796 
        Source to Destination Loss Period Length Min/Max: 1/17
        Source to Destination Inter Loss Period Length Min/Max: 1/2828
        Loss Destination to Source: 5746 
        Destination to Source Loss Periods Number: 4319
        Destination to Source Loss Period Length Min/Max: 1/17
        Destination to Source Inter Loss Period Length Min/Max: 1/321
        Out Of Sequence: 0      Tail Drop: 1
        Packet Late Arrival: 0  Packet Skipped: 0
Number of successes: 18
Number of failures: 30

Answer 1

this is a great document as well, but doesn't dive down deep enough. The best example would be Packet Loss, where is says -
Packet Loss
Five types of packet loss or assimilated events can be measured with IP SLA:
Packet loss in the source to destination (packetLossSD)
Packet loss in the destination source (packetLossDS)
Tail Drop: we know it has been dropped, but we do not know in which direction. This is when the last packet(s) of the test streams were dropped, because in this case, we do not receive the sequence numbers. In older releases, this is called Packet MIA for missing in action. In the MIB, the notation PacketMIA is still in use.
Packet Late Arrival: the packet did arrive, but so late that the underlying application probably considered it as dropped, or at least not useful. Think about a VoIP application. If one packet arrives much later than expected, it is too late because the conversation keeps going. This packet is assimilated to a drop.
Packet Misordering: the packet arrived but not in the right order. This may or may not be considered as a packet drop. (packetOutOfOrder)
The cool thing is the power that lies behind those numbers. Differenct values can be calculated the way you want it. For instance the total amount of packet dropped is:
packetDropped = RTTMonPacketLossSD + RTTMonPacketLossDS + RTTMonPacketMIA
The total percentage of packets that have dropped during the instance is:
drop_rate_%age = 100 * packetDropped / (RTTMonNumOfRTT + packetDropped)
Many other values can be calculated, and that is entirely up to you to decide what parameters are important.
But does not address the fields that I am looking for -
Source to Destination Loss Period Length Min/Max: 1/17
        Source to Destination Inter Loss Period Length Min/Max: 1/2828
        Destination to Source Loss Periods Number: 4319
        Destination to Source Loss Period Length Min/Max: 1/17
        Destination to Source Inter Loss Period Length Min/Max: 1/321
appreciate all the input though Vinod!
