Sample QoE database queries in Lync Server 2013
Topic Last Modified: 2012-10-17
This section contains sample queries for the Quality of Experience (QoE) database.
Use the following example to get the jitter and packet loss average for all audio streams.
select avg(cast(JitterInterArrival as bigint)) as JitterAvg, avg(PacketLossRate) as PacketLossRateAvg from AudioStream
Use the following example to find the total numbers of conferences that used Meeting Console.
select avg(ConversationalMOS)
from SessionView s
inner join MediaLineView m
on s.ConferenceDateTime = m.ConferenceDateTime
and s.SessionSeq = m.SessionSeq
and m.MediaLineLabel = 0 -- audio media line
and s.CallerUserAgentType = 4 -- Lync
and s.CalleeUserAgentType = 4 -- Lync
Use the following example to get ConversstionalMOS, SendingMOS and ListendingMOS per capture device.
select t.DeviceName as Device, count(*) as SampleNum, avg(ConversationalMOS) as ConversationalMOS, avg(SendListenMOS) SendingMOS, avg(RecvListenMOS) as ListendingMOS
from
(
select m.CallerCaptureDev as DeviceName, m.ConferenceDateTime, m.SessionSeq, a.StreamID, m.ConversationalMOS,a.SendListenMOS, a.RecvListenMOS
from MediaLineView m
inner join AudioStream a
on m.ConferenceDateTime = a.ConferenceDateTime
and m.SessionSeq = a.SessionSeq
and m.MediaLineLabel = 0
union
select m.CalleeCaptureDev as DeviceName, m.ConferenceDateTime, m.SessionSeq, a.StreamID, m.ConversationalMOS,a.SendListenMOS, a.RecvListenMOS
from MediaLineView m
inner join AudioStream a
on m.ConferenceDateTime = a.ConferenceDateTime
and m.SessionSeq = a.SessionSeq
and m.MediaLineLabel = 0
)as t
group by t.DeviceName
order by SampleNum desc
