After capturing the packets using wireshark. If try to open TCP stream throughput grapth. It is coming empty. On Y-axis it is not taking any input. Can any one help me with this. asked 16 Sep '15, 07:07  phaniK |
One Answer:
The Throughput graph only graphs one stream in one direction, based on the packet that is selected when you bring up the graph. It does not graph all packets in the trace. Look at the top of the graph and it will show you the source address and port, and the destination address and port, of the selected stream. The usual reason for the graph being blank is that data is flowing in only one direction, ACK packets are flowing back in the other direction, and you've selected a packet in the wrong direction. You need to select a packet in the direction of data flow, not the direction that the ACKs are flowing. The selected packet doesn't have to have data, but it has to be in the direction of data flow. If data is being sent from A to B, and ACKs are going from B to A, make sure you've selected a packet from A to B. This is true of all the graphs under Statistics > TCP Stream Graph. answered 17 Sep '15, 05:25  Jim Aragon |
Hard to make any suggestions without seeing the capture file. Can you post it somewhere? One idea: Make sure you selected a packet that contained data - the graph might be empty if there was only unidirectional flow,
