We'll summarize this quickly to show you exactly what the strengths and weaknesses of this software are: Using WMI and SNMP, you can get a good indication of the volume or amount of traffic at the IP level layer 3 level and give you a good indication of layer 2 and layer 3 counters and events, including errors and broadcasts you have. On the flip side, it also acts as a packet sniffer which will give you a good overview of Layer 4 services.
PRTG is a great tool if you looking to really scale up due to their vast list of sensors, alerts and alarms that are built into the program itself. Setup is a little more involved than our Top pick, be aware of that, but nonetheless, it's a great option. You can download a day free trial. The download is free to use indefinitely for up to sensors! Download PRTG. You can monitor bandwidth information either through the Web-Interface or Command-Line tools that they offer.
One of the only downsides to this program is that you'll need to have Python installed on your Machine before you install the desktop version of the tool. The program was last updated in August , but many are still using it to monitor usage of bandwidth in their networks. NetWorx is a fairly straight forward tool that we've recently reviewed and are including in this list.
This program is meant to monitor your Local Machine, but digging a little further into the documentation, you can see it has the ability to monitor traffic from a router or gateway that uses SNMP or uPnP protocols. NetWorx will Poll these devices every 1 second to plot all the data on a graph, and if your a home-user and are using a consumer-grade network device, chances are the device will not support polling at that frequent of an interval, but it's still worth a try. Its not a Fully-featured tool, but has the bones to get some good data, especially if you are trying to diagnose a particular machine or application.
Finding the right network traffic monitor for examining whats coming in and going out of your network is a good way of having full control over it. We recommend you grab one of these Free downloads and test to see which one works the best for your needs.
Some have more options than others, but all-in-all, a good network traffic and bandwidth monitoring software is going to show you the data you need to know — Which Device, Application or User is using the most bandwidth.
This tool includes mechanisms to resolve bandwidth issues through traffic shaping. Runs on Windows Server. Start a day free trial.
Available for Windows Server and Linux. Installs on Windows Server. BitMeter OS A free, open-source network monitor that is a little out of date but shows some very useful traffic throughput graphs. High traffic spikes indicate cyberattackers at work, so having access to this type of instant update can help you act fast and stop hackers before they unleash too much damage.
Unexpected decreases in traffic, as well as a complete lack of traffic, are evidence of a larger performance problem. With NTA, you get all of the bandwidth monitoring, network analysis , and intelligent alerts in Bandwidth Analyzer Pack, minus the in-depth wireless and multi-vendor network monitoring and network performance baselines. The platform features the visual correlation I love, complete with the drag-and-drop network performance analysis dashboard so you can drill into any network element and analyze traffic patterns over months, days, or minutes.
With NetFlow Traffic Analyzer, you can quickly identify bandwidth use by application, protocol, and IP address group to identify where bandwidth is being zapped. This level of analysis, paired with customizable network traffic reports displaying historical data and identifying peak bandwidth usage, empower you to adjust policies for better bandwidth management and avoid spending extra on additional bandwidth.
Beyond these features, if your business regularly uses cloud-based applications, like VoIP or e-commerce systems, the software can also be leveraged to verify prioritized traffic moves smoothly through the network.
This is an essential part of CBQoS policy optimization. This internet usage monitoring software allows you to measure all the traffic in your network by monitoring the data directly on your routers. PRTG Network Monitor also helps you determine how much bandwidth your devices and applications are using and monitor heavy overloads, so you can quickly and accurately pinpoint bottlenecks.
Depending on your network and hardware, you can use different protocols, like SNMP, flow, or packet sniffing, to leverage the tool and determine who or what is using your bandwidth. This all-in-one solution goes beyond bandwidth analysis and monitors SQL, Exchange, and server software as well as all your cloud and virtualization applications, making it an elaborately in-depth service offering.
You can even use the tool as a network speed monitor. The Windows-based PRTG tool comes in two editions: a free version for monitoring up to sensors and a commercial edition for those who need to monitor a greater number of sensors.
But depending on the volume of sensors you need to monitor, the software can quickly become a drain on your budget. ManageEngine NetFlow Analyzer touts itself as a complete traffic analytics tool, and for good reason.
Once you have access to analytics, you can classify applications hogging your network bandwidth and even reconfigure your policies via application-level QoS shaping, helping you regain control over those bandwidth-hungry applications. The security features of this bandwidth monitoring tool are also worth noting. While many of the more robust products come with a price tag, there are some great free options for IT technicians looking to capture the basics.
This free bandwidth usage meter allows you to check server bandwidth usage in real-time and monitor multiple interfaces simultaneously.
All bandwidth usage data is displayed visually via graphs to help you perform more critical analysis. This tool is free and straightforward to use. Simply enter the IP address of the network device and associated SNMP credentials, then select the interfaces you want to monitor, and a graph will populate with bandwidth usage in real-time—no complicated install processes to worry about here. Leveraging both tools makes it easy to quickly identify the types of network traffic by flow data capture—including NetFlow, J-FLow, and sFlow data—and provides multi-interface monitoring for bandwidth usage in real-time.
It offers a bit more detail than some of the other free options out there by allowing you to see traffic by conversation, app, domain, and endpoint.
The platform allows users to sort network traffic according to a wide range of criteria, including IP address, port, L7 protocol, autonomous systems, and more. Ntopng displays network traffic and active hosts in real time, so you can stay up to date while producing historical reports to review data and better identify trends. Benefits of flow monitoring over others: Analyze traffic usage by applications, users, protocols and QoS.
Faster troubleshooting with conversation level details. Provides real-time diagnostics with up to one-minute granularity. Requires less data storage as compared to other monitoring techniques.
Provides accurate information on bandwidth utilization to make critical decisions. Supports advanced technologies like NBAR that gives payload info within packets for analysis. Detects network security threats. Deep dive into your network traffic with the free network bandwidth monitor NetFlow Analyzer is a flow-based, free bandwidth monitoring tool for Windows and Linux that helps you monitor and analyze network traffic and troubleshoot bandwidth issues in real-time.
Create custom dashboards to add important widgets to your NOC view.
