Join Lancher Test

To enhance the quality of conferencing, the Microsoft Skype for Business server has introduced a new join launcher feature. The Skype for Business server updates the join launcher to validate each meeting before launching a client. When the meeting URL has been activated the Skype for Business Server runs the join launcher service. The main steps performed by the join launcher are:

  • Determine language to use based on preferred language(s) in the browser and the language packs installed on the server. If no direct or indirect match (parent) can be found between preferred language(s) and the language packs installed on the server the server language will be used;
  • It will convert the SimpleUrl based URL to the real URI used to join the meeting;
  • Determine if the web request came from the Internet or from the internal network by looking at which web site was used;
  • Determine which client to launch based on the installed client(s).

Using this test, administrators can figure out how many times the join launcher service failed and how many incoming requests were received. This way, administrators can be proactively alerted to performance/connecitivity issues in the Microsoft Skype for Business 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.


The host for which the test is to be configured.


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

Measurements made by the test
Measurement Description Measurement Unit Interpretation

Join failures

Indicates the number of times the join launcher service failed.


Ideally, the value of this emasure should be zero. A sudden/gradual increase in the value of this measure indicates that the join launcher service is not inititated properly or there is a performance/connectivity issue in the Skype for Business server.

Incoming join requests

Indicates the number of incoming join requests i.e., meeting validation requests to the join launcher service.
