Network Quality Summary Test

If your Microsoft Teams users complain of inaccessibility or poor audio/video call quality, you may want to check the quality of the network link to the Micorsoft Teams. A flaky or latent network connection to the Microsoft Teams server can sometimes deny users access to Microsoft Teams application. Also, sometimes, the calls/meetings may end abruptly before the users do so thus adversely impacting their overall experience with Microsoft Teams. To proactively figure out the reason behind such flaky network and to ensure Quality of Service at all times, administrators can periodically run the Network Quality Summary test.

This test when executed periodically reveals any break or slowness in the network connection to Microsoft Teams. Using this test, administrators can measure the user experience in terms of network quality and figure out the real reason behind poor network connections - is it due to jitter? or packet loss? or round trip? or audio degradation?

Target of the test : Microsoft Teams

Agent deploying the test : A remote agent

Outputs of the test : One set of results for the monitored Microsoft Teams

Configurable parameters for the test
Parameters Description

Test period

How often should the test be executed

Host

The host for which the test is to be configured. By default, this is portal.office.com

O365 User Name, O365 Password, and Confirm Password

For execution, this test requires the privileges of an O365 user who has been assigned the Service support admin role and is vested with the View-Only Audit Logs and Team administrator permissions. Configure the credentials of such a user against O365 User Name and O365 Password text boxes. Confirm the password by retyping it in the Confirm Password text box.

While you can use the credentials of any existing O365 user with the afore-said privileges, it is recommended that you create a special user for monitoring purposes using the Office 365 portal and use the credentials of that user here. To know how to create a new user using the Office 365 portal and assign the required privileges to that user, refer to Creating a New User in the Office 365 Portal.

Domain, Domain User Name, Domain Password, and Confirm Password

These parameters are applicable only if the eG agent needs to communicate with the Office 365 portal via a Proxy server.

In this case, in the Domain text box, specify the name of the Windows domain to which the eG agent host belongs. In the Domain User Name text box, mention the name of a valid domain user with login rights to the eG agent host. Provide the password of that user in the Domain Password text box and confirm that password by retyping it in the Confirm Password text box.

On the other hand, if the eG agent is not behind a Proxy server, then you need not disturb the default setting of these parameters. By default, these parameters are set to none.

Proxy Host, Proxy Port, Proxy User Name, Proxy Password and Confirm Password

These parameters are applicable only if the eG agent needs to communicate with the Office 365 portal via a Proxy server.

In this case, provide the IP/host name and port number of the Proxy server that the eG agent should use in the Proxy Host and Proxy Port parameters, respectively.

If the Proxy server requires authentication, then specify the credentials of a valid Proxy user against the Proxy User Name and Proxy Password text boxes. Confirm that password by retyping it in the Confirm Password text box. If the Proxy server does not require authentication, then specify none against the Proxy User Name, Proxy Password, and Confirm Password text boxes.

On the other hand, if the eG agent is not behind a Proxy server, then you need not disturb the default setting of any of the Proxy-related parameters. By default, these parameters are set to none.

Show Top N DD

By default, this parameter is set to 10, indicating that the detailed diagnostics will report the top-10 data. You can change the 'N' in Show Top N DD by specifying any number of your choice in this text box.

DD Frequency

Refers to the frequency with which detailed diagnosis measures are to be generated for this test. The default is 1:1. This indicates that, by default, detailed measures will be generated every time the test runs, and also every time the test detects a problem. You can modify this frequency, if you so desire. Also, if you intend to disable the detailed diagnosis capability for this test, you can do so by specifying none against DD Frequency.

Detailed Diagnosis

To make diagnosis more efficient and accurate, the eG Enterprise embeds an optional detailed diagnostic capability. With this capability, the eG agents can be configured to run detailed, more elaborate tests as and when specific problems are detected. To enable the detailed diagnosis capability of this test for a particular server, choose the On option. To disable the capability, click on the Off option. The option to selectively enabled/disable the detailed diagnosis capability will be available only if the following conditions are fulfilled:

  • The eG manager license should allow the detailed diagnosis capability
  • Both the normal and abnormal frequencies configured for the detailed diagnosis measures should not be 0.
Measurements made by the test
Measurement Description Measurement Unit Interpretation

Overall avg network mean opinion score

Indicates the average Network Mean Opinion Score degradation for stream.

Number

This measure is a good representation of how much the network loss and jitter had impacted the quality of received audio.

Max jitter

Indicates the maximum jitter for stream.

Milliseconds

 

Max packet loss rate

Indicates the percentage of maximum packet loss for stream.

Percentage

 

Avg ratio of concealed samples

Indicates the ratio of the number of audio frames with samples generated by packet loss concealment to the total number of audio frames for streams.

Percentage

 

Avg send listen mean opinion score

Indicates the average of the prediction of the Wideband Listening Quality Mean Opinion Score (MOS-LQ) of the audio stream that is being sent from the user.

Number

 

Avg ratio of stretched samples

Indicates the average ratio of the number of audio frames with samples that have been stretched to compensate for jitter or loss to the total number of audio frames for streams.

Percentage

 

Avg round trip Max

Indicates the average of maximum network propagation round-trip time computed as specified in RFC3550 for streams.

Milliseconds

 

Avg round trip

Indicates the average of average network propagation round-trip time computed as specified in RFC3550 for streams.

Milliseconds

 

Avg packet loss rate

Indicates the average of average percentage of packets lost computed using 5 second interval for streams.

Percentage

 

Avg network jitter min

Indicates the average of minimum network jitter values computed over 20 second windows during the session for streams.

Milliseconds

 

Avg jitter

Indicates the average network jitter for streams.

Milliseconds

Ideally, the value of this measure should be low.

The detailed diagnosis of this measure lists the Date, hour, first UPN, second UPN, First IP address, second IP address and the average jitter.

Avg audio degradation

Indicates the Average Network Mean Opinion Score degradation for streams.

Number

 

The detailed diagnosis of the Avg jitter measure lists the Date, hour, first UPN, second UPN, First IP address, second IP address and the average jitter. The user network with high jitter can be pointed out using this detailed diagnosis.
