This problem is easy to find on the graph, but it may not be so obvious when looking at the message list.Ī filter condition can be applied to each graph. If you see traffic drop to zero in some places, it may be a problematic point. From this picture, we can see that the peak rate is about 300kbps. Change the Y axis to bits/tick so that you can see the flow per second.

This display under default conditions is not very useful in most troubleshooting. Note: The filter condition is empty, this graph displays all traffic. This packet capture is a situation where the HTTP download encounters packet loss. To check further, click any point in the graph to see the details of the message.įor the convenience of explanation, click the sample packet, or click Statistics-IO Graphs with your own wireshark. This is a basic application and is very helpful for viewing the peaks/valleys in the flow. If you want to view the number of bits or bytes per second, click 'Unit' and select the content you want to view from the 'Y Axis' drop-down list. The default X-axis time interval is 1 second, and the Y-axis is the number of packets in each time interval. The basic Wireshark IO graph will display the overall traffic in the captured file, usually in units of per second (number of packets or bytes).
