Tools of choice to monitor bandwidth and network usage in 2021

Let me tell you a story of a Carlsbad resident Eddie Sanchez, who was notified of excessive internet consumption like four other TDS customers.
Have a look at this letter:

The company urged him to upgrade from residential to business internet because his excessive network bandwidth consumption slowed down the network.
I think it's pretty obvious that nobody likes slow internet in today's fast-paced life, and having no idea about the root of the problem doesn't help a bit.
But, let's face it, we all have been there when end users keep complaining about slow internet though there is plenty of bandwidth available according to your calculation.
I hope that we all can agree that it's not a desirable situation and to avoid it we need to understand what causes such problems.
Keep reading to find a one-step solution to handle this issue!

What is Network Bandwidth monitoring?
Before I explain the network bandwidth monitoring process, let me tell you a bit of bandwidth to understand the process quickly.
Bandwidth refers to the maximum amount of data transmitted between devices or the internet within a given amount of time.
I think you've probably heard someone asking: "Who is monopolizing my bandwidth?" It's just someone complaining about a slow network connection, and it happens a lot in public places.
It's because public places are full of network users trying to use the internet at once, and this high-data activity causes the network speed to lag.
Now, this is where network bandwidth monitoring comes into play. It is a method for measuring the actual bandwidth available on a local system (LAN or WiFi).
The exact amount and type of bandwidth any organization requires depends mainly on the size of the business. However, any network brimming with laptops, phones, and other devices must be equipped with ample bandwidth capacity to provide a fast and efficient experience for all the users.
Why do you need a Network Bandwidth Monitoring tool?
- Determining your network's bandwidth requirements
- Efficient network performance
- Economic benefit
- Extra protection
Usually, the IT administrators only get alerted when there is a network interruption, and at that point, they are obligated to be reactive rather than proactive.
Since foresight is better than hindsight, IT administrators need to keep track of their network to handle performance issues quickly.
It's when network bandwidth monitoring comes into play. Its advantages are listed below:
Determining your network's bandwidth requirements
Network Bandwidth monitoring provides you helpful insight about the network's bandwidth requirements at the start that allows you to avoid significant overhauls down the line.
With the right network bandwidth monitoring tool, you can determine the bandwidth needs of your enterprise's local area network (LAN) or vast area network (WAN).
You can also evaluate when your company needs to upgrade bandwidth, including adding a new division of employees to your company or converting laptops from PCs.
Efficient network performance
Network monitors also come in handy to boost the performance of your network by providing you with a proper visual display of your bandwidth and network health.
This information allows you to spot bottlenecks at a glance, analyze and monitor traffic patterns, availability, track response time, switches, uptime of routers, and other SNMP-enabled devices.
Economic benefit
Investing in additional bandwidth can sometimes be an expensive undertaking, and thus, one must know how to troubleshoot slowdowns without this investment.
A bandwidth monitoring tool provides insight into granular and big-picture network usage information to head off issues instead of investing in additional bandwidth.
Extra protection
Moreover, Network Monitoring can potentially protect your company from data breaches.
Monitoring bandwidth usage empowers you to quickly detect any suspicious activity by providing a detailed snapshot of potentially malicious traffic flows.
How should you choose a Network Bandwidth monitoring tool?
Although there are a lot of advantages of using network bandwidth monitoring tools, you need to choose the right tool according to your company's requirements.
With the increase in network usage monitoring tools and bandwidth monitors, finding the perfect match for your company becomes confusing.
It' why I have provided a detailed guide of the 11 best Network Bandwidth Monitoring Tools (2021) so that you can choose the one that suits you best.

The SolarWinds Real-Time Bandwidth Monitor is our all-time favorite network bandwidth monitoring tool and it.
Before I tell you about the valuable features of this product, let's look at a sneak-peek of how this valuable tool works:
The SolarWinds Real-Time Bandwidth Monitor uses SNMP to poll multiple network interfaces in real-time for their traffic statistics and shows the status of a chosen interface with the help of a graph.
The following steps show the working of the Real-Time Bandwidth Monitor.
- This tool lists the SNMP interfaces and shows primary data once provided with the IP address and SNMP parameters for the device or host.
Image source − solarwinds.com
- Upon selection of one of the interfaces from the list, the Bandwidth Monitor provides you a graphical display of bandwidth usage on that interface.
Image source − solarwinds.com
- Finally, this tool provides you the option of setting per-interface thresholds so that the graph displays an alert when usage exceeds the chosen limits.

Now let's have a look at some of the features which make this product valuable:
- The SolarWinds Real-Time Bandwidth Monitor comes bundled with the Real-Time NetFlow Traffic Analyzer, which provides a lot of insight about devices that support NetFlow.
- As a tool, it's elementary to learn as it has no unnecessary features or blot.
- It is an essential tool for monitoring devices that don't support the traffic flow monitoring protocols (NetFlow).
- It provides an accurate and precise visual representation of traffic flow with time and events.
- It allows you to set up per-interface thresholds and flexible alerts for both large and small networks.
- With the help of a free network, the analyzer allows the user to see traffic by conversation, app, domain, and endpoint.
- It can be installed on Windows Operating System.
The SolarWinds Real-Time Bandwidth Monitor is a highly recommended tool for IT professionals. Still, some of its features might be overwhelming to non-technical users, such as its requirement to configure the Universal Device Poller in templates from web GUI.

ntopng
Pros
|
Cons
|
---|---|
|
|
"ntopng" is an open-source web-based traffic analysis tool with a completely free community version, whereas its professional and enterprise versions require buying a license.
Some valuable features of this tool are listed below:
