Data MCU Details Test

The Data MultiPoint Control Unit (Data MCU) on the front end server serves the Whiteboarding and presentation options to the users. When a Powerpoint presentation is uploaded to a meeting using Skype for Business, the file is actually uploaded to the Data MCU. This Data MCU returns a broadcast URL representing the uploaded file, causing the Skype for Business server to start an embedded browser file inside the client. The URL returned to the client is the URL of the Office Web Apps server, that retrieves the file from the Data MCU using the Web Open Platform Interface (WOPI) protocol and renders the slides into web-based presentable data. Every second, the browser frame pings the Office Web App server using AJAX to confirm which slide should be previewed. This information is sent back to Skype for Business 2013 Client’s embedded browser frame, thus moving the presentation along. For the Skype for Business client to receive whiteboards and presentations without any technical glitch, it is essential to monitor the health of the Data MCU server. This is where the Data MCU Details test helps! Using this test, you can figure out the health and draining status of the Data MCU server along with the numerical statistitcs of the MCU users, active conferences and the whiteboards served by the Data MCU server.

Target of the test : A 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

Session queues state

Indicates the state of the session queues.

Number

If the value reported by this measure is 1, then it indicates an overload condition.

MCU users

Indicates the number of users in the Data MCU server.

Number

 

Active conferences

Indicates the number of conferences that are currently active on the server.

Number

 

DataMCU health state

Indicates the current state of the Data MCU 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 Data MCU 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 DataMCU

Indicates the current draining status of the Data MCU 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 Data MCU 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.

Annotations

Indicates the number of annotations i.e., whiteboards served by the Data MCU server.

Number

 

Content objects

Indicates the number of content objects in the Data MCU server.
