The first thing that you see when you look at the Network Monitor is the “Devices” section.

This is the section of the Network Monitor that allows you to choose which of your devices will be displayed on the Download and Upload graphs.

By default, all of the devices are selected, but you can easily remove a device so that it does not appear on the usage graphs by clicking on it. Once you click on it, you will see that it goes grey and the tick box next to the device will be un ticked, to show you that it is not selected.

By default, your Network Monitor will look as above, with all devices selected to be viewed on the usage graphs.

You can deselect some of your devices so that only specific devices are seen on the usage graphs.

Network Monitor Graphs

The Network Monitor utilises Stacked Area Graphs to show you which of your devices are using your internet and how much of the bandwidth they are using.

When you are using the internet, the usage will show up on the upload and download graphs, depending on what you are using the internet for.

Using the Network Monitor Graphs

The graphs are made so that they easily display the usage of certain devices using your network.

Only selected devices will show up on the graph.

You can see that hardly any bandwidth is being used show by the "Total Usage" percentage.

If you were to do a more bandwidth intensive task such as watching YouTube, downloading a file etc the usage on the graph would increase.

You can click certain points on the graph to see what is using up the bandwidth.

Once you click the point on the graph, a side bar will appear with a chart of which service is using up your bandwidth. In the screen shot above, HTTPS, HTTP & ports are showing. HTTPS/HTTP will usually mean something in your browser.

You can the further narrow it down to specific devices. For example I can select a device and view exactly what it was using the bandwidth for at the time that I clicked the point on the graph. You can select a device by using the drop down box above the chart.
