The I/O graph feature is a convenient tool for measuring throughput through the network. We can use it to measure the traffic and throughput of any predefined filter. In this recipe, we will see some examples of how it can be used to measure throughput in a network.
Throughput measurements with I/O graphs
Getting ready
Connect your laptop to the network with Wireshark, with the port mirror to the link you want to measure, as you learned in Chapter 1, Introduction to Wireshark Version 2. Start a new capture or open an existing file, and then open the I/O graphs from the Statistics menu.
