These guides introduce features and functionalities of Qosium, and how to use them.
For learning material, please refer to Get Started with Qosium instead.
Qosium needs to see the network traffic to be able to measure passively. Qosium Probe also comes with an optional feature to take packet captures, Pcap files, from the measured traffic. The packet trace is taken from the traffic that matches your measurement filter. You can open the Pcap file with the preferred packet analyzer tool. This guide demonstrates how you can perform packet capturing with Qosium Scope. Packet capturing is something that can also be taken off from a Qosium delivery.
When you have a large network with many Qosium Probes installed, keeping track of each Probe and their IP addresses can become cumbersome. Qosium comes with a feature that allows you to find all your Qosium Probes in the network.
One-point measurement enables you to measure and monitor traffic in a single point. You see, for example, traffic loads, packet counters, and traffic flows. In a single point, QoS parameters, such as delay, is not possible to be measured as they need a reference point. QoS measurement relates to measurement between two points in the network. However, jitter and packet loss can be calculated for certain applications such as RTP and MPEG.
NAT changes packet content, which brings a new challenge on passive QoS measurement. However, Qosium can manage this and you can measure QoS over a network path where there is a NAT deployed between.
When Qosium Probe is involved in measurement having geographical location information, you can visualize all Qosium statistics as a heatmap. This feature is useful when measuring wireless networks to determine the network's performance in relation to location. Problem areas can be found out quickly, which helps optimize network coverage and initiate recovering actions.
