Qosium Probe is not directly operated as such since Qosium measurements are controlled fully by a measurement controller. However, there are certain operative functionalities, like license activation and launching, that are discussed in this section.
Qosium Probe needs a license to run. The license information is locally stored in a license file located in Probe’s installation folder. The license can be pre-activated, like, for example, in the academic license. In this case, Qosium usage can be started right after the installation.
In installation-limited licenses, each Qosium Probe needs to be activated online. The activation is carried out simply by using Kaitotek’s License server as follows:
A successful activation is typically so fast that the user does not even notice it: the controller just connects the Probe as usual. If something goes wrong, error information is delivered via the measurement controller. An activated Qosium Probe will is fixed to the device. However, the installation be also moved to another device.
Once Qosium Probe has been parameterized, it is time to launch it. Typically, Qosium Probe is set to run as a system service. In this way, it always starts with the platform, being ready for measurements. This also has the advantage that running Qosium measurements does not require administrative rights in the platform.
Qosium Probe can also be run as a normal application. This can be useful in some special cases since Probe’s log window will be visible. Administrative rights, however, are needed when launching the Qosium Probe application.
The way of launching Qosium Probe is dependent on the platform. These are discussed in the following subsections:
If you have an installation-limited license, it is possible to transfer an activated Qosium Probe to another device. In practice, Qosium Probes can always be installed without limits, but in installation-limited license models, only a certain number of them can be in use. Thus, transferring Qosium Probe from one device to another is, in practice, transferring the license.
License transfer is carried out as follows:
QosiumProbe licunreg
sudo QosiumProbe licunreg
Qosium Probe is typically run as a Windows service. However, it can also be run as a normal desktop application. This section describes how to run Probe on Windows, and what options are available.
This section goes through starting of Qosium Probe on Linux based systems. The launching of Qosium Probe depends on whether it is installed as a system service or as to be started manually.
Qosium Probe agent is started with the same Qosium Probe Android Launcher that was used to install it.
