Wireshark is available for Windows and macOS. It offers real-time usage monitoring and data capture.

You can turn your network data into graphs and charts to help make them more usable. While Wireshark is easy to use, it’s not as straightforward as some of the other tailormade usage monitoring platforms on this list. If you wanted to see the performance information of a certain application, you would need to click Statistics > Conversions and click on the tab you wish to see more information on.

If you’re looking for a free network usage monitoring tool Wireshark is a good choice, but it doesn’t have as much to offer as SolarWinds Netflow Traffic Analyzer and ManageEngine Netflow Analyzer. As a result, users looking for a comprehensive network usage monitoring tool would be best advised to pass on Wireshark despite its competitive offering. Wireshark can be downloaded from here.

Network Usage Monitoring Tools: The Bare Necessities

The rapid advance of network infrastructure and the rise of disparate and complex distributed IT environments means most organizations need some form of network usage monitor tool. Trying to maintain a large network without one is next to impossible because you simply won’t be able to systematically address poor connectivity or faults when performance issues emerge.

All of the tools we’ve outlined above are solid choices for network transparency. However, if you really want to get the most out of your usage monitoring, our top picks are SolarWinds Netflow Traffic Analyzer and ManageEngine Netflow Analyzer. These two tools straddle the line between a clean user interface and the capacity to delve deep into your network usage.

These tools rise to the challenge of providing users with a tool that allows top-down monitoring as well as individual application usage monitoring. If you’re serious about improving your network performance on an enterprise scale, these two platforms are well-worth considering.

That being said, no two enterprises are the same, so it is important to weigh up the advantages of each package before you decide to make a purchase or start deployment. Incorporating a quality network usage monitor into your administrative toolkit will ensure you stay productive on an ongoing basis.

What is Network Monitoring and Why is it Needed?

Network monitoring is the practice of monitoring your IT infrastructure and looking for inefficiency or faults. In many cases this is simply scanning through your network devices to make sure no key services are down or compromised. For example, you could check on the usage statistics of web servers and easily see when a service has failed. In the event that your network experiences downtime, you can then set a usage monitor tool to notify you via email or SMS to take action.

There are many reasons why network monitoring is needed, such as:

  • Troubleshooting Network Performance
  • Bandwidth Capacity Planning
  • Monitoring Bandwidth Usage

The primary reason most administrators incorporate network usage monitor tools to troubleshoot network performance. For example, if you have a department using massive amounts of data, you can identify the individual devices eating through data supply. A network monitor will help you to see the top talkers and help explain what causes extensive data usage on the network.

Many network administrators employ usage monitor tools for bandwidth capacity planning. Every device on your network takes its toll on performance and speed. An administrator can use a network usage monitor tool to see how many devices your network can sustain before it needs to be upgraded. Once signs of poor performance emerge, the administrator will be able to identify when your service needs to be upgraded.

Finally, if you have an agreement with an ISP to cap bandwidth consumption, then it is extremely useful to have a usage monitor tool to ensure you don’t go over your monthly allowance. This will not only help to make sure you don’t incur any additional charges, but will also allow you to verify that your ISP is providing you a level of connectivity in line with what you originally agreed.

How do Network Usage Monitor Systems Work?

In a nutshell, network usage monitor systems work by sending ping signals to ports across your IT infrastructure. Once the monitor sends a ping, it then waits for a response from the targeted port. Generally speaking, most systems send ping tests every hour, though many can do so as frequently as every minute. The length of time between the ports’ response can highlight poor performance and latency. Below we’ve broken down some of the core components that every great network monitoring system should have:

  • Continuous Monitoring – You need a tool that gathers data 24/7. Ideally you’re looking for a program that does so without adversely affecting your network performance.
  • Individual App Data – In order to get a clear view of what is happening on your network, a tool that can show you data on individual apps to help identify the top talkers is vital.
  • Remote Monitoring – If you belong to a larger enterprise, remote monitoring is important as it allows you to gather data from disparate locations and view it from a centralized location.

Network usage monitors can report data back to administrators from devices across the network all the way down to individual nodes and interfaces. Many quality usage monitoring platforms allow the user to set predefined alerts and create their own graphs and reports for deeper analysis.

Deploying a network usage monitor

The purpose of network usage monitors is to detect when traffic levels approach full bandwidth capacity. You need to know what traffic volumes represent normal everyday activity on your network so that you can judge whether you have the right bandwidth capacity available. Budget considerations may force you to squeeze the most out of your infrastructure budget by providing capacity that is below the peak in demand.

If you have periods where the bandwidth is not fully utilized, you can reschedule batch jobs away from times of high demand, or practice traffic shaping measures. You can also examine which applications and protocols use up the most bandwidth and investigate more efficient alternative to reduce the load on the network. In order to fulfill both monitoring and planning requirements, you need to measure a baseline to establish what is considered normal and peak activity on the network.

Continuing monitoring should highlight an inevitable growth in activity over time, so you can adjust your record of normal and peak activity levels. Once you have your normal capacity records, you can set alert levels on each of your devices to notify you once traffic volumes exceed normal activity is exceeded. Other alerts can notify you when processing rates drop on a network device because that condition would indicate a fault with that piece of equipment. Knowledge of the capacity of each network device and regular usage figures will help you plan for extra demand on the system that requests for new applications or extra user endpoints will create.

Surges in network traffic might also indicate anomalous behavior, which would indicate intrusion. So, network usage monitors can also play an important role in your network security checks. Network usage monitoring tools have a range of purposes and will prove useful assistance in your network monitoring and planning tasks. Heck out the free trials and demo versions of the tools listed in out recommendations to see how a network usage monitor tool can improve your system administration working practices.
