Measures reported by LSAVMcuTest
A/V conferencing enables real-time audio and video communications between the Lync 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 Lync server so that administrators may proactively be alerted to abnormalities/technical glitches in the conferences. This is where the LS LSAVMcuTest 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 connectity status events in the A/V Conferencing server etc. This way, administrators can easily identify the load on the Microsoft Lync server.
The measures made by this test are as follows:
| Measurement |
Description |
Measurement Unit |
Interpretation |
| Conference |
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 Lync server. |
| CreatedConf |
Indicates the number of conferences created during the last measurement period. |
Number |
|
| BYESent |
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. |
| HealthState |
Indicates the current health state of the A/V conferencing server. |

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

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. |
| MPContext |
Indicates the number of active media processing contexts in the A/V Conferencing server. |
Number |
|
| CreateContext |
Indicates the number of CreateContext requests received by the A/V Conferencing server during the last measurement period. |
Number |
|
| RTPConStatus |
Indicates the number of RTP Endpoint connectivity status events on the A/V Conferencing server during the last measurement period. |
