6 Best Bandwidth Monitoring Tools

By SolarWinds on April 9, 2021


Your network relies on reliable data transmission. Not only could troublesome connections yield negative results for customers, but connectivity issues could also indicate deeper problems within your network. However, if you monitor your bandwidth consistently and carefully, you can maintain your network’s health and solve issues as they arise.

It’s hard to monitor bandwidth by yourself, so I suggest investing in a network bandwidth monitor. Network bandwidth monitoring software can analyze each devices’ bandwidth consumption while saving you energy, resources, and brainpower. My two top picks for bandwidth monitoring are from SolarWinds—SolarWinds® NetFlow Traffic Analyzer (NTA) and the network bandwidth analyzer pack (BAP) offer extensive bandwidth monitoring capabilities designed to help ensure your network’s speed is maintained and managed properly.

What Is Network Bandwidth Monitoring?

Network bandwidth monitoring observes your network’s bandwidth usage through tracking patterns and discovering details to help you better understand your bandwidth’s status and determine your network needs.

Bandwidth is a network’s capacity to transmit data between devices. It’s an amount of time, usually measured in bits per second (bps), although larger multiples can also be used. Higher bandwidth yields faster rates of data transfers, which allows your network to support more connected devices. If networks are roads, bandwidths determine the size—the more bandwidth, the more space for information to travel.

Even the best bandwidth network is susceptible to issues like latency, jitters, packet drops, and congestion. Bandwidth monitoring determines if your network’s bandwidth is working fast and reliably and devices are using a fair and healthy amount of bandwidth.

Benefits of Network Bandwidth Monitoring

Bandwidth monitors enable you to easily keep track of your network’s bandwidth usage, customize bandwidth distribution, and discover potential bottlenecks and outages. Here are some actions you can achieve with help from a bandwidth monitoring tool:

Dive Into Detail

A bandwidth monitor could gather bandwidth statistics on specific devices plus your entire network, helping paint a complete picture of your network’s bandwidth use. Some bandwidth monitoring software even enables the creation of visual graphics, like charts and top lists, allowing you to compare device bandwidth data.

Prep for the Future

Network bandwidth monitors are designed to constantly look out for bandwidth hogs, traffic congestion, and other potential threats, so you’re never scrambling to solve problems. Many bandwidth monitors can identify trends indicating a greater bandwidth need and will notify you when you’re due for an upgrade in bandwidth capacity.

Display Data in Real Time

Many bandwidth monitors automatically update their information, keeping your statistics live and everyone on the same page. Real-time data graphics enable you to clearly understand your network’s bandwidth information, helping make better decisions about bandwidth utilization and spot issues.

Boost Network Performance

By analyzing traffic patterns, response times, and up/down time of devices, bandwidth monitoring tools allow you to better know how your network is performing. Also, excessive bandwidth can sometimes be an indicator of deeper problems—by detecting troublesome devices, network bandwidth monitors may help you discover other critical issues.

Save Money and Time

Deciding to expand your bandwidth can be a difficult decision, and bandwidth monitoring tools can help you determine the best time to grow your network’s bandwidth threshold. Bandwidth monitoring software is designed to help you discover solutions to bandwidth shortages, traffic congestion, and other bandwidth performance issues before purchasing unneeded bandwidth capacity.
