Communicator Web Application Test

If data collaboration is enabled in your conferencing policy then you (and anyone else who participates in a meeting that you organized on the Microsoft Skype for Business server) will have the following three capabilities at your disposal: PowerPoint Presentation, New Whiteboard, and New Poll. This test helps you to figure out the data collaboration authentication requests that failed, the SIP connections that failed and the data collaboration client connections that were closed due to throttling. In addition, you can figure out the number of active SIP connections and the amount of data that is queued for data collaboration. This way, administrators may figure out how well the data collaboration enabling is helpful for users to access powerpoints, polls etc.

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.

The port at which the specified host listens. The default port is 5060.

Measurements made by the test
Measurement Description Measurement Unit Interpretation

Rate of failed data collaboration authentication requests

Indicates the rate at which data collaboration authentication requests failed.



Data collaboration connection failures

Indicates the number of data collaboration connections that failed on the server.



Rate of SIP connection failures

Indicates the rate at which the SIP connections failed on the server.


A low value is desired for this measure. A sudden/gradual increase in the value of this measure indicates that the SIP connection was terminated unexpectedly due to network issues or due to the unavailability of remote servers.

Rate of data collaboration client connections closed due to throttling

Indicates the rate at which the data collaboration client connections were closed due to throttling on this server.


A low value is desired for this measure. Often data collaboration of the client connections failed due to the inability of the client to read data efficiently on the server. This may be due to the failure of network or organized attack.

Queued data for data Collaboration server connections

Indicates the amount of data that is queued for data collaboration server connections.


A high value for this measure indicates the failure to read outgoing data by the Web Conferencing servers.

Active SIP connections

Indicates the number of SIP connections that are currently active.
