In contrast, sFlow can cover Layers 2 through 7. A device collecting NetFlow metrics in its flow cache exports them periodically based on active and inactive timeouts. Thus reports on recent and ongoing conversations may be delayed, depending on the timeouts. In contrast, sFlow sends collected packet prefixes and counters in real-time. We reviewed the market for NetFlow analyzers and collectors and analyzed the options based on the following criteria:.

Below, we look at several popular NetFlow-based network monitoring and analysis tools for Windows. All are sophisticated, having a considerable learning curve; so online training and good support are essential. It features bandwidth monitoring , traffic analysis , performance analysis , alerts , customizable reports , policy optimization , and more.

The NetFlow Traffic Analyzer gathers flow data exported by the flow-enabled devices tracked by the SolarWinds network monitoring software. As a flow analyzer, NTA identifies the users, applications, and protocols consuming the most bandwidth.

You can sort by ports, source, destination, and protocols, and view traffic patterns over minutes, days, or months. NTA and NPM are enterprise-grade packages, so even the free trial will consume considerable resources on your system. You can also start a day free trial. Noction Flow Analyzer offers three main strategies to network managers. These are to monitor and control bandwidth utilization , to implement capacity planning , and to detect and prevent network performance problems.

The system has a striking front-end. You are free to choose between the Light, Dark, or Auto theme options. Here, below, you can see the Data Explorer screen, which provides detailed network traffic stats in both graphs and report forms.

All data queries can be subsequently saved as widgets and placed on dashboards. Multiple dashboards can be set up in NFA. These are the collections of graphs that are typically grouped by a specific purpose, e. The network monitoring system lets you see live traffic data with the facility to examine traffic at each node or look at ends-to-end traffic between two given points. You can set up alerts on any of the metrics that the Flow Analyzer collects. These are thresholds that will activate alerts when they are crossed.

These alerts can be sent to technicians via email or Slack, so staff does not need to watch the network monitor unless a problem is developing. The system creates a Web server so the screens for the system are accessed through any standard Web browser. Despite hosting the service yourself, you do not buy the software outright. Instead, you pay a subscription, with a rate per month or per year. There is one add-on service, which is to collect Border Gateway Protocol internet routing data from the network gateway.

You can try the Noction system on a day free trial. Auvik is a network monitoring and management platform that is delivered from the cloud. The service is offered in two plan levels: Essentials and Performance. The Essentials has fewer facilities than the Performance edition. The Auvik system is able to communicate with switches to extract traffic flow data using NetFlow v5 and v9. The package then displays traffic data per link or across the network in terms of applications or source and destination addresses.

This enables you to see where most of your traffic originates. Communications outside the network can be shown on a world map , identifying where most connections are made to. A throughput graph shows a time-series record of all traffic that travels from the network onto the internet.

The traffic analyzer is just one of the network monitoring systems built into the Auvik platform. With information on traffic per link, you can switch to the network topology map and device inventory to identity the capacity of each switch and get time to head off capacity exhaustion. As well as performing constant network monitoring, Auvik includes network configuration management , which will standardize device settings and prevent unauthorized changes.

The Performance plan has a log server in the package and it is also possible to integrate the service with a third-party Service Desk, project management, and observability systems. Access a day free trial to assess Auvik. The ManageEngine NetFlow Analyzer provides real-time visibility into network bandwidth and traffic patterns. The tool visualizes traffic by applications, conversations, protocols, etc. Alerts can be set based on traffic thresholds.

There are a variety of useful predefined reports, ranging from troubleshooting oriented to capacity planning and billing. Custom search reports can be created. The web-based user interface has a default dashboard with several real-time pie charts, including a heat map showing the status of monitored interfaces, top applications, top protocols, top conversations, recent alarms, top QoS, and more. Hovering over a graphic usually provides an explanatory pop-up, and clicking on any graphic drills down to more details on the selected element.

There are specific displays for detecting security issues. Dashboards are customizable. Alerts show up as pop-ups on the user interface. Multi-site traffic can be analyzed; there is a smartphone app for mobile monitoring and alerting. The tool leverages advanced features of Cisco devices, including support for adjusting the traffic shaping and QoS policies on your network.

The free version allows unlimited monitoring for 30 days but then reverts to monitoring only two interfaces. ManageEngine has various related products to expand beyond NetFlow traffic-oriented data analysis into a full network management suite. Download the day free trial. Site24x7 Network Traffic Monitoring is a cloud-based traffic analyzer that forms part of several system management packages. Site24x7 offers infrastructure monitoring, website management, and an application performance monitor, and a system for managed service providers.

This tool provides live network traffic monitoring and also stores data for capacity planning and trend analysis. As a cloud service, the dashboard is accessed through any standard web browser. All of the processing for the service is performed on the Site24x7 servers but there also needs to be an agent installed on site. The monitor communicates with network switches through a number of protocols. The system extracts traffic statistics and it can also sample packet headers.

The information taken from traffic enables the traffic monitor to identify traffic per application, per source and destination, and per user account. The system can communicate with the network devices supplied by more than vendors. As well as spotting traffic hogs, the analyzer shows time-series graphs and can identify peak hours. This information allows network managers to squeeze extra value out of existing resources by moving non-urgent tasks such as batch administration processes to less busy periods of the day.

The information shown by the network monitoring system is able to plot traffic loads link by link and also end to end across the network. It is able to spot bottlenecks and assist in traffic-shaping measures, such as queuing and prioritization.

The monitor imposes performance thresholds that are set at levels that allow time to fix problems. If a threshold gets tripped, the service generates an alert. This is shown on the system console and can also be sent out to key personnel as an email, SMS, or voice-calls.

An All-in-One package from Site24x7 offers all of the services included with all of its other bundles and that includes the traffic monitoring system. All of the plans and editions of Site24x7 are available for day free trials. The free version provides unlimited sensors for a month, and thereafter is limited to sensors; a sensor is an individual data stream, so each device will typically require several sensors.

Devices include firewalls, routers, access points, servers, workstations, virtual servers, storage, etc. The device tree is supplemented by table views of sensors, logs, and alarms, as well as various charts and graphs for bandwidth, etc. Tables can be sorted and filtered. Drilling down through the tree view reveals indicators and metrics at every level. Settings, like scan interval , are inherited and can be overridden at lower levels in the device tree.

Alerts can similarly be set at every level , so you can arrange to be notified about events and threshold transitions of a particular critical device, or rolled up from an overall aspect of your network. The devices-and-sensors abstraction shapes the dashboards and reports too. Custom dashboards can be created, including interactive maps. There is a range of predefined reports, and facilities for designing custom reports; reports can also be scheduled.

Traffic analysis facilities include built-in NetFlow support. Installation is straightforward. There is a setup wizard, as well as a video providing step-by-step guidance. Additional sensors including NetFlow collectors can be added manually; a video provides instructions. The core server is Windows only. Monitoring of a single site can be done via the web application, but the simultaneous view of multiple core servers requires using the enterprise app on Windows.

A mobile app is also provided. One clever addition is that PRTG provides QR codes that can be pasted on particular devices for a quick look-up and status in the mobile app. PRTG supports clustering for fault tolerance: you can set up failover instances of the monitor. To evaluate, you can download a day free trial. The community version of ntopng is free. The professional small business and enterprise versions require a paid license , but are free to educational and nonprofit organizations.

So the use of NetFlow data is limited unless you qualify for a free license. Most categories have multiple views, a mix of charts, tables, and graphs; and in each you can drill down to explore in depth and cross-reference. Tables can be sorted — so for instance, selecting the throughput column on the flows table shows the current top bandwidth users.

The flow display shows application protocols e. Facebook, YouTube. Latencies and TCP statistics e. Alerts can be set on hosts based on many criteria, and will show up as an icon in the user interface. The professional version can save and display historical application usage statistics, do active monitoring via SNMP, generate custom traffic reports, and several other additional features. The installation package for both ntopng and nProbe is a zip file containing a standard Windows setup wizard.

The installer will install winpcap for packet sniffing if needed. Since ntopng is open source, there is considerable scope for extending it. It supports both NetFlow and sFlow. Scrutinizer can be installed as a dedicated physical appliance , as a virtual machine running on a server, or as a SaaS solution running in the cloud public or hybrid.

Scrutinizer is designed for high network performance and scalability from small to very large environments. It provides a rich range of analysis and reporting features. The trial includes full access for 30 days. After that, the free version has a limit of 10K flows collected per second, five hours of raw flows kept, and one week of historical summaries maintained.

The paid version includes notifications, dashboard customization, custom reports, scheduled email reports, and support. Other utilities in the package include a Cloud Ping service, which checks the availability of devices within the network from an external perspective, and an internet traffic counter, which logs outgoing traffic volumes by destination country. The processor for the Auvik software is hosted in the cloud and the package also includes storage space for statistics and logs.

The service is accessed through a console, which is available through any standard Web browser and can be customized. You can get a look at Auvik with a day free trial. Get Free Trial! Site24x7 is a cloud-based service that is able to monitor systems that are located on-premises or in the cloud.

The system queries network switches in order to gain status information and, by another method, to gain traffic statistics. These languages are used by the network equipment provided by more than vendors. The data gathered by agents on site is uploaded to the Site24x7 servers where it is processed and then shown in the system dashboard. Traffic volumes are shown live and also stored for time-series historical analysis.

Site24x7 offers a range of monitoring bundles, each focusing on a different aspect of IT systems. All of these bundles include the network traffic monitoring module. All of those plans are available for a day free trial.
