Throughput measurements with I/O graphs
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.
Getting ready
Connect your laptop to the networkwith 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 theStatisticsmenu.
When measuring the throughput, we can measure it on a communication line between end devices (PC to server, phone to phone, PC to the internet) or to a specific application:
The process of isolating network problems starts from measuring traffic over a link, between end devices, or on single connections to see where it comes from.
Some typical measurements are host-to-host traffic, all traffic to a specific server...
