Besides graphing bandwidth, NetWorx provides several tools like a speed meter and a per-user usage report. ManageEngine produces a full network management suite and offers free versions of some of their tools. In our article on the best free NetFlow analyzers and collectors for Windows , we looked at the ManageEngine NetFlow Analyzer which provides real-time visibility into network bandwidth and traffic patterns, when you have devices that support NetFlow.
The NetFlow Analyzer displays traffic by applications, conversations, protocols, etc; it can alert you to problems and has a range of report-generation options.
It runs on Windows or Linux. The free edition supports monitoring 10 devices and their interfaces. Setting up the OpManager is a multi-step process but not overly complex. You can view graphs and tables of network usage, speed, and bandwidth, as well as device hardware metrics, either rolled up at the device level or drilling down to a particular interface. At the interface level, you can generate reports showing bandwidth from the past 12 hours up to the past month.
You can also set thresholds to receive automated alert email or SMS messages. By monitoring the gateway to your ISP, you can check your internet traffic usage and how much bandwidth you actually receive. The Bandwidth Monitoring tool, combined with the other features of the free version of ManageEngine OpManager, provides you with a well-rounded suite of capabilities for monitoring 10 or fewer devices on a small network. The community version of ntopng is free; the professional small business and enterprise versions require buying a license.

Licenses are free to educational and nonprofit organizations. The tool first traces all of your devices and lists them in a left-hand menu panel in the interface. You can switch between devices just by selecting a different IP address in the list. The main panel of the screen shows live traffic and distinguishes the applications sourcing each traffic flow with different colors.
With this display, you can see all of the applications operating on the network simultaneously. That segmentation of traffic can also be switched to show the endpoints, domain or protocol that generates the traffic instead of the applications. It can also compress the display to identify each active exchange, or conversation, being carried out on the network.
The tool runs on Windows and it is only intended for quick checks. WhatsUp monitors network traffic, servers, virtual servers, cloud services, and applications. The free version is a free five-point license for monitoring up to five resources eg, five servers. WhatsUp must be installed on Windows. Setup is simple and uses auto-discovery.
The user interface provides multiple views with an interactive network map and the ability to drill down to investigate issues. Dashboards are customizable. WhatsUp provides many canned reports, including reports for bandwidth and utilization; you can design customized reports, too.
You can configure alerts to notify you when senders or receivers exceed bandwidth thresholds when interfaces exceed utilization thresholds, etc.
There are multiple possible methods for notification, including email and SMS. Triggered actions give the ability to execute actions automatically as responses to alerts. You could also implement queueing at switches to ensure that priority, interactive traffic always gets through unhindered. SolarWinds NetFlow Traffic Analyzer is our top pick for a bandwidth monitoring tool because it can communicate with network devices that are provided by many manufacturers and extract categorized traffic statistics.
The data stored by the tool can be used within the dashboard for historic analysis, identifying traffic growth trends and the peaks and troughs in different types of traffic. With this knowledge, you can re-plan your physical infrastructure and introduce traffic shaping to reduce the risk of overloading. Download: Start day Free Trial.
