The AppSharingStream table contains Quality of Experience metrics for the network streams used for application sharing. This table was introduced in Microsoft Lync Server 2013.
Column | Data Type | Key/Index | Details |
---|---|---|---|
ConferenceDateTime |
dateTime |
Primary, Foreign |
Date and time that the session started. |
SessionSeq |
int |
Primary, Foreign |
Sequential identifier used to distinguish between sessions that started on the same date and at the same time. |
MediaLineLabel |
tinyint |
Primary, Foreign |
Represents the type of video line used in the call. Allowed values are:
|
StreamID |
int |
Primary |
Unique identifier of the application sharing stream. |
JitterInterArrival |
int |
Average jitter detected between RTP packet arrivals. (Jitter is a measure of the "shakiness" of a call.) High jitter values are typically caused by congestion or an overloaded media server, and result in distorted or lost audio. |
|
JitterInterArrivalMax |
int |
Maximum jitter detected between RTP packet arrivals. (Jitter is a measure of the "shakiness" of a call.) High jitter values are typically caused by congestion or an overloaded media server, and result in distorted or lost audio. |
|
RoundTrip |
int |
Average amount of (in milliseconds) required for a Real-Time Transport Protocol packet to travel to another endpoint and then back. Round-trip times of 200 milliseconds or less are considered of acceptable quality. High round-trip values can be caused by international call routing; a routing misconfiguration; or an overloaded media server. High round-trip times result in difficulties with two-way, real-time audio conversations. |
|
RoundTripMax |
int |
Maximum amount of (in milliseconds) required for a Real-Time Transport Protocol packet to travel to another endpoint and then back. Round-trip times of 200 milliseconds or less are considered of acceptable quality. High round-trip values can be caused by international call routing; a routing misconfiguration; or an overloaded media server. High round-trip times result in difficulties with two-way, real-time audio conversations. |
|
PacketLossRate |
float |
Average rate of Real-Time Transport Protocol (RTP) packet loss. (Packet loss occurs when RTP packets, a protocol used for transmitting audio and video across the Internet, failed to reach their destination.) High loss rates are generally caused by congestion; lack of bandwidth; wireless congestion or interference; or an overloaded media server. Packet loss typically results in distorted or lost audio. |
|
PacketLossRateMax |
float |
Maximum rate of Real-Time Transport Protocol (RTP) packet loss. (Packet loss occurs when RTP packets, a protocol used for transmitting audio and video across the Internet, failed to reach their destination.) High loss rates are generally caused by congestion; lack of bandwidth; wireless congestion or interference; or an overloaded media server. Packet loss typically results in distorted or lost audio. |
