I noticed some spikes in network traffic utilization. I want to be able to determine what generated that traffic at that time.

How do I do that?

 

Colasoft Capsa captures and analyzes the traffic from the start to the end of the capture. If you want to view the traffic details of some spike, you can go to the conversation views or the Packet view to drill down the traffic of that time period when the spike occurs. It is not convenient.
But, with Colasoft nChronos, you can view the traffic details of any time period, any spike conveniently, by just some clicks.
You are recommended to use Colasoft nChronos.
