Traffic overview

After having configured the options discussed in the previous sections, everything is now ready to start monitoring your Internet traffic 🕵️‍♂️

As soon as your machine will exchange any network data, you'll be able to see several real-time statistics in the the Overview page of the app.
As the name suggests, this page provides an high-level overview of your traffic in the form of an insightful dashboard of your Internet activity.

The most prominent section of the page is a live chart depicting the traffic rate relative to the latest 30 seconds of analysis;

• the upper part of the chart represents incoming data intensity, that is the amount of data your machine is receiving from the network every second
• in a similar way the bottom part of the chart reports outgoing data, or in other words the traffic that your machine is sending to other hosts

The chart is updated once per second to always display the most recent activity, reporting on the horizontal axis the number of seconds elapsed since the start of the monitoring session.

Moving away from the chart, we notice that the top left portion of the page includes a section providing other useful information — let's examine it a little deeper.

Starting from the top left, we can find details about the network adapter monitored: this is the same device that was previously selected for inspection in the initial page of the application.
In addition to the name of the device, it's reported its link type, that defines the kind of link-layer protocol used by the adapter.

Note

The most common kind of link type is Ethernet, a technology widely adopted both by local and wide area networks.
In addition to Ethernet, Sniffnet supports monitoring network adapters based on raw IPv4, raw IPv6, and Null/Loopback.
Other link types are currently unsupported, but this shouldn't be a problem for the vast majority of use cases.
