AppSharingMetricsThreshold table

  • Article

The AppSharingMetricsThreshold table contains optimal and acceptable values for the Quality of Experience metrics used with application sharing. These thresholds are used to determine if the application sharing experience should be classified as poor.

This table was introduced in Microsoft Lync Server 2013.

Column Data Type Key/Index Details
CallType
int
Primary
Type of call that was placed.
AppliedBandwidthLimitOptimal
int
Optimal bandwidth limitation for application sharing. The default value is 1000000.
AppliedBandwidthLimitAcceptable
int
Acceptable bandwidth limitation for application sharing. The default value is 500000.
SpoiledTilePercentTotalOptimal
decimal(5,2)
Optimal percentage rate for "spoiled" tiles for classifying an Application Sharing quality. This value is the percentage of the content from the sharer that didn't reach the viewer. Content might be discarded (or spoiled) when the sharer discards tiles from the graphics source or the ASMCU tiles discards tiles from Sharer respectively. The default value is 11 percent.
SpoiledTilePercentTotalAcceptable
decimal(5,2)
Acceptable percentage rate for "spoiled" tiles for classifying an Application Sharing quality. This value is the percentage of the content from the sharer that didn't reach the viewer. Content might be discarded (or spoiled) when the sharer discards tiles from the graphics source or the ASMCU tiles discards tiles from Sharer respectively. The default value is 36 percent.

float

RelativeOneWayBurstDensityAcceptable
float

RDPTileProcessingLatencyBurstDensityOptimal
float
This column isn't used in Microsoft Lync Server 2013.
RDPTileProcessingLatencyBurstDensityAcceptable
float
This column isn't used in Microsoft Lync Server 2013.
RelativeOneWayAverageOptimal
float
Optimal value for the relative one-way delay between the two media endpoints involved in the application sharing. This is a single-hop latency measure. The default value is 1.0 seconds.
The column was introduced in Microsoft Lync Server 2013.
RelativeOneWayAverageAcceptable
float
Optimal value for the relative one-way delay between the two media endpoints involved in the application sharing. This is a single-hop latency measure. The default value is 1.75 seconds.
The column was introduced in Microsoft Lync Server 2013.
RDPTileProcessingLatencyAverageOptimal
float
Optimal value of the average RDP tile processing latency in the AS Conferencing Server over the duration of the viewing session. Latency is the time difference between when the Start Frame is encoded on the server (sharer or MCU depending on the scenario) and the same Start Frame is decoded on the viewer.
A high average reflects a longer delay in the viewing experience. An overloaded conferencing server might experience higher average delays. The default value is 200ms.

RDPTileProcessingLatencyAverageAcceptable
float
Acceptable value of the average RDP tile processing latency in the AS Conferencing Server over the duration of the viewing session. Latency is the time difference between when the Start Frame is encoded on the server (sharer or MCU depending on the scenario) and the same Start Frame is decoded on the viewer.
A high average reflects a longer delay in the viewing experience. An overloaded conferencing server might experience higher average delays. The default value is 200ms.
