Help you check for security vulnerabilities and hopefully make your network more difficult to hack.

See packet transfer speeds between devices, and how much data has been transferred.

Help you diagnose and isolate network problems.

See the actual traffic as it occurs, as well as taking and saving time-framed snapshots that you can review.

These are just a few reasons to use network monitoring tools on your home network: Some of this you know about, and some you never see. On their own, all of these devices generate varying degrees of traffic on the local network, and adding human intervention, a wired and/or WIFI network is doing a lot of communicating. Besides just attaching a few computers and a router, many of today’s home networks are likely to have joined: a Server, a specialized media center PC, a media player, a Smart TV, a blue-ray player, a network printer, an audio-video receiver, a gaming device (or two), a Voice-Over-IP telephone system, a network switch (or two), along with WiFI and its attachments (cell phones, tablets, etc.). Simply put, Linux network monitoring tools allow you to see what is going on in your home network. Why Do You Need Linux Network Monitoring Tools?
