Learn whether Qosium is compatible with your operating system or device
Does Qosium work in Windows 8, Windows 10, and Windows Servers?
Yes. In fact, Windows is one of the most used end-device platforms with Qosium.
Is MacOS/OSX supported?
Yes, Qosium Probe and Qosium Scope are available for MacOS/OSX.
What Linux operating systems are supported?
In practice, all Linux-based operating systems are supported. The most popular Linux distributions are supported directly, such as Ubuntu, Debian, CentOS, RedHat, Fedora, Gentoo, and other distributions based on them. However, with some Linux distributions, we need to know the details of your Linux build to be able to provide you with an installer package. These include, for example, Yocto and OpenWRT.
Does Qosium work in Android?
As with other Linux-based systems, Qosium Probe is available for Android devices as well. In fact, many of our users carry out measurements with Android phones. Qosium Scope is currently not available for Android, but measurements on Android phones can be controlled remotely.
Remember, however, that Qosium Probe must be run with administrator privileges on Android devices. See more information, see our documentation on installing Qosium Probe on Android.
Does Qosium work in iOS?
Qosium is not currently available for devices running iOS. However, please contact us if you have a need for this and let’s discuss more.
Do you support FreeBSD?
Yes, Qosium is available for FreeBSD as well.
Can I install Qosium to Raspberry Pi?
Sure, Qosium Probe is made very light-weight and can be run also on resource-constrained devices. Qosium is verified to work on Raspberry Pi 3 and Pi 4.
I have a network device with a hardware-specific operating system. Can I install Qosium to that?
Suppose we can prepare a build environment, and the device allows installing third-party software. In that case, we most likely can provide you with a software package for that device. Please get in touch with us to discuss your device more. If installing to that specific device is not possible, there are also other means to enable measurement. We gladly assist you in defining measurement scenarios.

Qosium Trial and Evaluation Edition - How to try out Qosium for free before purchasing
What is the difference between Trial and Evaluation Editions?
Trial Edition is a free version that you can use to learn how to use Qosium and to find out if Qosium is suitable for your needs. It has a few functional limitations, akin to a “demo version”. You can download the Trial Edition any time by signing up. See the Qosium Trial Edition Install Guide for more instructions.
Qosium Evaluation Edition is functionally identical to the Full Edition but with a much shorter license duration. This edition is ideal for testing Qosium with full capacity for a limited duration. You can request the Evaluation Edition for free by filling out this form: Request Qosium Evaluation Version.
How can I get Qosium Trial Edition?
Please sign up first. After submitting the form, a welcome email will be sent to your email address, which will instruct you to set a password for your account. After setting the password, you can sign in and download Qosium Trial Edition. The whole process takes only a few minutes.
For more detailed instructions, see our guide.
How can I get Qosium Evaluation Edition?
Please fill out this request form or send a request to supportkaitotek.com. We will ask you all the necessary details about operating systems and then deliver the Evaluation Edition software packages.
The Trial Edition only contains Qosium Probe and Scope. How can I test Qosium Scopemon and Qosium Storage?
Unfortunately, the Trial Edition package doesn’t feature products for automatic monitoring (Qosium Scopemon and Qosium Storage). However, they are available as Evaluation Edition on request. Thus, please send us a direct request at supportkaitotek.com, or use this request form.
Is trying out Qosium really free?
Yes, and we even offer support for the trial period. You can safely try out Qosium without any commitments. After the trial period, we may contact you to ask whether you found Qosium useful and would like to proceed to commercial usage.
The forms require an organization name. Can I test Qosium at home first before bringing it up at my workplace?
Although we offer licenses mainly only for organizations, it’s perfectly reasonable to test Qosium out of the office first. Just fill out the organization name you work for, or alternatively type “Private”. You can also use your personal email account, such as Gmail.
Do you provide support during the free trialing period?
Sure, we want to ensure that you always get the most out of testing. If you wish, we are happy to provide you with training to use Qosium, help you with the measurement setup, and assist in results analysis. For free training, please send us an email to saleskaitotek.com.
Where can I find the user documentation? Can I access it without an Internet connection?
We provide online documentation, which you can export as PDF (See the Export to PDF option in the navigation section on the documentation page).

Where can I see the license models and prices?
Please fill up a contact form price query or contact us by email saleskaitotek.com. We are happy to provide you with information and prices for different licensing models. We have commercial license models for yearly, daily, and project usages. In addition, we have a separate license model for academic use.
I'm a researcher, student, or teacher. How can I get Qosium for my university?
At Kaitotek, we have carried out over 10-years long research phase for Qosium. We want to support education and research work and have prepared a separate license model for this usage. Don’t hesitate to get in touch with us at saleskaitotek.com to hear more.
QoS, QoE, and network measurements with Qosium
Can I measure uplink and downlink directions separately?
Yes, Qosium measures always sent and received directions separately. Communication problems may show up only in the other direction, and with Qosium, you can detect that quickly and easily.
Our applications have strict demands for latencies (order of milliseconds). Can I measure latencies that accurately?
Qosium can measure delays even in microseconds accuracy. Thus, Qosium can verify that your applications have their strict requirements for network connections met at all times.
In order to measure such small delays, the clocks between the two measurement points have to be synchronized. There are several options to achieve this, which are explained here.
What does passive measurement mean?
Most network performance measurement solutions available are active ones. They generate artificial test traffic to measure the QoSQuality of Service
Indicates the overall performance of the network and its ability to serve applications. and/or QoEQuality of Experience
Indicates the overall performance of a network application, and how user’s experience is affected by the network conditions.. These tools are handy when making maximum performance measurements and testing new networks before real application traffic.
However, when you want to measure and monitor the performance of a network already taken into operative use, you likely want to know how well the network performs in serving the real applications rather than burdening it with test traffic. Passive measurement solutions come into play when measuring how the real applications experience network quality.
Please find more information from our Qosium Documentation: Passive QoS Measurement.
We have a network operation and management system in use. Can I integrate passive QoS/QoE measurement into that?
With the APIApplication Programming Interface
An interface in software, which allows a third party to interact with the software programmatically. that we provide, Qosium can be integrated into existing external systems, such as network management solutions. This API gives you complete control of measurements with your Qosium Probes in the network. This includes everything from the parameterization of measurements to collecting measurement results in real time. Learn more about integration in here.
Partial integration is also possible. In this case, Qosium’s control tools (Qosium Scope, Scopemon, or Scope Lite) drive the measurements, but an external system collects the results. This type of integration is very trivial.
We need network measurements, but all of this is too overwhelming.
Delving into communication networks’ performance can sometimes be challenging due to, for example, lack of resources to do the work or complex network setups. Kaitotek also provides network measurement services. We can do the measurements for you and provide you with a detailed analysis of the network’s true quality and performance. Please take a look at Kaitotek Services.
I am a Wireshark expert: why should I switch it to Qosium?
We also use Wireshark a lot! Qosium does not replace Wireshark or the other way around since they are two different tools for different purposes. Qosium is a QoS measurement tool, while Wireshark is a protocol analyzer.
For example, in troubleshooting, the joint use of Wireshark and Qosium increases working efficiency, saving time and money. Qosium can take traffic captures from a measurement point in the well-known pcap format, allowing the use of Wireshark in conjunction with QoS measurements.
Qosium allows you to find network QoS problems quickly. You can get a hint of what the disruption is about (e.g., occasional delay spikes). After this, you can take Wireshark and dig into the traffic itself at the correct place to see if there are hints of what is causing the behavior. Sometimes the root causes for the problems cannot be seen directly in the traffic when generated by, for example, a malfunctioning network device.
