Measures reported by OpenVPNLicenseTest

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 OpenVPNLicenseTest 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.

The measures made by this test are as follows:

Measurement Description Measurement Unit Interpretation
Total_license Indicates the total number of licenses that are available for this server. Number The value of this measure is the sum of the License_used and the Available_lic measure.
License_used Indicates the number of licenses that are currently in use. Number If the License_used measure is equal to the Total_license measure, then the Available_lic 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 License_used measure reaches close to the Total_license, so that they may marginally increase the number of licenses.
Available_lic Indicates the number of licenses that are currently available for use. Number
Percentage_used Indicates the percentage of licenses that are currently in use. Percent
