Qosium Scope

Qosium Scope is a real-time analyzer for managing Qosium measurements. It activates and controls Qosium Probes over a network connection. Essential features are measurement parameterization, running measurements, results collection, and results visualization. Qosium Scope is an excellent tool for directed QoS and QoE measurements.

Starting measurement

A measurement wizard helps you make the initial parameterization:

Alternatively, measurement points can be set manually:

Qosium comes with a registration feature for Qosium Probes. The Probe registration feature overcomes the device reachability issue with dynamic IP addresses. Instead of IP addresses, Probes are identified based on their unique ID given by you. Probes in the network register their existence to a selected central Probe. Qosium Scope then tells what measurement agents there are in the network available for measurements. This is a handy feature for finding and selecting measurement points in a large network. In addition, Probe registration gives an indication of network node availability, comparable to Ping.


Qosium Scope comes with an extensive set of parameters to configure measurements. However, parameterizing a typical measurement is still easy and most parameters are such that you don’t need to touch. All the parameters and visualization settings can be, naturally, saved, making it easy to return to an earlier measurement.

Results analysis

Measurement results can be visualized in multiple ways. Meters, graphs, bars, and numerical formats, it’s up to you how you want to take a look at results. Results are averaged over desired period. From average results, one can drill into packet results, where QoS results of every single packet is shown.

Changing between different visualization types is easy. You can also select the measures for visualization freely and on run-time from a large set of results measures.

QoS heatmap is perhaps the most elegant feature of Qosium Scope. If Qosium Probe has location information available during a measurement, Qosium Scope allows visualizing any measure measured (for example, delay) on a map even in real time. Qosium Scope makes it possible to find out the coverage area of a wireless network, not in terms of signal strength but in terms of the actual quality experienced by end-users.

It is possible to also bring your own overlay images to Qosium Scope's map. This can be, for example, a building layout for indoor wireless measurements. Satellite positioning don’t work well indoors, but location information can also be given by clicking a mouse, or by using some other positioning technique.

Heatmap visualization can be parameterized to satisfy your needs. This includes, for example, ruling color coding, defining drawing precision, and selecting map style.

In addition to QoS results, Qosium Probes extract overall network traffic to traffic flows. Flow analysis in Qosium Scope shows which network devices talk with whom through the node Qosium Probe is running. It is also a simple way to recognize if there are interesting applications traversing the Probe node.

Storing the results

All measurement results can be saved to a file, which can later be loaded back to Scope or taken easily to some other tool for analysis work. The results can be also sent to a data base, such as Qosium Storage, in real time.

Qosium can also take packet captures from the traffic being measured. This is an optional feature, which can also be left out completely from a build, if desired. A pcap file is generated, which can be taken, for example, to Wireshark for accurate protocol analysis. Packet capture is taken from Layer-2 level, which ensures that also MAC layer protocol headers are included.
