LS Audio/Video Details Test

A/V conferencing enables real-time audio and video communications between the Skype for Business users. In environments where users use A/V conferences for communication, it becomes mandatory for the administrator to check the quality of the A/V Conferencing experience and the load on the Microsoft Skype for Business server so that administrators may proactively be alerted to abnormalities/technical glitches in the conferences. This is where the LS Audio/Video Details test helps. Using this test, you can easily figure out the health of the A/V Conferencing server, the number of conferences that were created and those that are currently active, the number of RTP endpoint connectivity status events in the A/V Conferencing server etc. This way, administrators can easily identify the load on the Microsoft Skype for Business server.

Agent deploying the test : An internal/remote agent

Outputs of the test : One set of results for the target Microsoft Skype for Business server that is to be monitored.

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.

Port

The port at which the specified host listens. The default port is 5060.
Measurements made by the test
Measurement Description Measurement Unit Interpretation

Active conferences on the A/V conferencing server

Indicates the number of conferences that were active on the A/V Conferencing server.

Number

This measure is a good indicator of the load on the Microsoft Skype for Business server.

Created conferences

Indicates the number of conferences created during the last measurement period.

Number

 

SIP Bye messages sent by A/V conferencing server

Indicates the number of SIP BYE messages sent by the A/V Conferencing server during the last measurement period.

Number

To deliver a conference invitation, the inviting user sends a special sort of SIP INVITE message to the user who is being invited. Instead of Session Description Protocol (SDP) content, this INVITE message has an XML document with conference details as its body. The invitee sends a 200 OK acknowledging this INVITE, and as soon as the SIP handshake has finished it immediately ends the SIP dialog with a BYE message.

AVMCU health state

Indicates the current health state of the A/V conferencing server.

 

The values that this measure can report and their corresponding numeric values have been listed in the table below.

Measure Value Numeric Value
Normal 0
Loaded 1
Full 2
Unavailable 3

Note:

By default, this measure reports the above-mentioned Measure Values while indicating the current health of the A/V Conferencing server. However, in the graph of this measure, states will be represented using the corresponding numeric equivalents i.e., 0 to 3.

 

Draining status of the AVMCU

Indicates the draining status of the A/V Conferencing server.

 

The values that this measure can report and their corresponding numeric values have been listed in the table below.

Measure Value Numeric Value
Not requesting to drain 0
Requesting to drain 1
Draining 2

Note:

By default, this measure reports the above-mentioned Measure Values while indicating the draining status of the A/V Conferencing server However, in the graph of this measure, states will be represented using the corresponding numeric equivalents i.e., 0 to 2.

When a server is drained, it stops taking new connections and calls. These new connections and calls are routed through other servers in the pool. A server being drained allows its sessions on existing connections to continue until they naturally end. When all existing sessions have ended, the server is ready to be taken offline.

Active media processing contexts

Indicates the number of active media processing contexts in the A/V Conferencing server.

Number

 

CreateContext requests received

Indicates the number of CreateContext requests received by the A/V Conferencing server during the last measurement period.

Number

 

Total RTP Endpoint connectivity status events

Indicates the number of RTP Endpoint connectivity status events on the A/V Conferencing server during the last measurement period.

Number
