Measures reported by MTMAudioStrmsTest
A/V conferencing enables real-time audio and video communications between the Microsoft Teams users. In environments where users use audio streams for communication, it becomes mandatory for the administrator to check the quality of the audio conferencing experience and the load on the Microsoft Teams so that administrators may proactively be alerted to abnormalities/technical glitches in the conferences. This is where the MTMAudioStrmsTest test helps.
Using this test, you can easily figure out the total number of audio streams and the count of audio streams that were classified as poor, good and unclassified. Administrators can also figure out the reason on why the audio streams were classified as poor-is it due to high roundtrip? or high packet
loss? or jitter? or high degradation?
Outputs of the test : One set of results for the monitored Microsoft Teams.
The measures made by this test are as follows:
| Measurement |
Description |
Measurement Unit |
Interpretation |
| AUcfStm |
Indicates the number of streams that were marked as Unclassified. |
Number |
A stream is marked Unclassified when Interactive Connectivity Establishment (ICE) connectivity fails or when all the metrics required to compute the stream classification are not reported.
If ICE connectivity succeeded for an Unclassified stream, the stream is likely considered Unclassified because key stream metrics were not reported. There are a few reasons these metrics may not be reported:
|
| AStrm |
Indicates the total number of audio streams. |
Number |
|
| APrStm |
Indicates the total number of audio streams that were classified as poor. |
Number |
|
| APrPrct |
Indicates the percentage of audio streams that were classified as Poor. |
Percentage |
|
| APrDRndTp |
Indicates the number of times the audio was classified as poor due to high roundtrip. |
Number |
The detailed diagnosis of this measure lists the start time, end time, first UPN, second UPN, first IP address, second IP address, conference ID and the number of times the audio was classified as poor due to high roundtrip. |
| APrDPktLs |
Indicates the number of times audio was classified as poor due to large amount of packets being
lost. |
Number |
The detailed diagnosis of this measure lists the start time, end time, first UPN, second UPN, first IP address, second IP address, conference ID and the number of times the audio was classified as poor due to large amount of packets being lost. |
| APrDJtr |
Indicates the number of times audio was classified as poor due to jitter. |
Number |
The detailed diagnosis of this measure lists the start time, end time, first UPN, second UPN, first IP address, second IP address, conference ID and the number of times audio was classified as poor due to jitter. |
| APrDDgdtn |
Indicates the number of times audio was classified as poor due to average network mean opinion score degradation. |
Number |
This measure indicates how much network loss and jitter have impacted the quality of received audio.
The detailed diagnosis of this measure lists the start time, end time, first UPN, second UPN, first IP address, second IP address, conference ID and
the number of times audio was classified as poor due to average network mean opinion score degradation. |
| APrDCnclRt |
Indicates the number of times audio was classified as poor due to average ratio of the number of audio
frames with concealed samples generated by packet loss healing to the total number of audio frames. |
Number |
The detailed diagnosis of this measure lists the start time, end time, first UPN, second UPN, first IP address, second IP address, conference ID and the number of times audio was classified as poor due to average ratio of the number of audio frames with
concealed samples generated by packet loss healing to the total number of audio frames. |
| AGdStm |
Indicates the total number of audio streams that were classified as Good. |
