5 Free Internet Traffic Monitoring Tools

Internet access is becoming a necessity of the modern living. People in first-world countries are continually accessing the Internet. Consequently, Internet data plans are becoming expensive as well due to the demand. As such, it is essential to monitor your usage and bandwidth.

Why to Monitor Internet Usage & Bandwidth?

Internet data plans are expensive. Especially when, you are living in a large metropolitan area. You are paying your Internet Service Provider for a specific amount of bandwidth. Moreover, most plans also come with the dreaded data cap.

It is worth noting how much data and bandwidth you are using. You should have the information available whether you are on unlimited connection or limited data cap.

You do not have to be a network engineer to understand your computer's network activities. There are tools which can summarize the information for you.

Internet plans with at least 60 Mbps are almost $60 per month on average in the United States. In some areas, it is close to $100 such as in the United Arab Emirates. It does not include additional data for capped services. Therefore, it is important to budget your data allowance every month.

It is still necessary to monitor your network activities even if you are on unlimited data. Common issues such as buffering video streams lag in online gaming, and choppy VoIP connections may stem from mismanaged bandwidth.

It is possible that you are receiving lower bandwidth than you are paying. However, sometimes apps on your computer eat up connection without your knowledge. You may be receiving enough bandwidth, but some programs are hogging your bandwidth.
