OpenVPN User License Test

A license is always required for the OpenVPN Access server installation. It can either be a free license or a purchased license. Once the server is installed, each license carries a maximum number of concurrent users who will be able to connect to the server. Depending on the number of users connecting to the OpenVPN Access servers, multiple licenses can be obtained. In case of purchased licenses, the maximum number of concurrent user count is additive and in the case of free licenses, the user count is not additive. If multiple free licenses are activated, then the user count will be the maximum of the individual user counts for each free license. Administrators may constantly need to track the utilization and availability of the licenses so that end user experience in connecting to the OpenVPN Access server would not be affected at all! This is where the OpenVPN User License test helps! This test monitors how well the licenses are managed by the OpenVPN Access server. This way, the administrators can figure out from a single glance the total number of licenses, the licenses that are already exhausted and the licenses that are available for future use.

Target of the test : An OpenVPN Access Server

Agent deploying the test : An internal/remote agent

Outputs of the test : One set of results for the OpenVPN Access server that is to be monitored.

Configurable parameters for the test
Parameter Description

Test period

How often should the test be executed.


The host for which the test is to be configured.


The port number at which the specified Host listens to. By default, this is NULL.

Measurements made by the test
Measurement Description Measurement Unit Interpretation

Total licenses

Indicates the total number of licenses that are available for this server.


The value of this measure is the sum of the Licenses used and the Available licenses measure.

Licenses used

Indicates the number of licenses that are currently in use.


If the Licenses used measure is equal to the Total licenses measure, then the Available licenses measure would be 0 which clearly indicates that all the licenses are already exhausted. This would terribly affect the user experience with the OpenVPN Access server. Therefore, administrators may want to be alerted when the Licenses used measure reaches close to the Total licenses, so that they may marginally increase the number of licenses.

Available licenses

Indicates the number of licenses that are currently available for use.
