Monitoring network traffic is essential in keeping it secure and efficient. Effectively monitoring your network traffic can be classified into five steps:
Data sources can predominantly be classified into flow data, sourced data from layer 3 devices, and packet data.
For efficient network monitoring, it is essential to to monitor every single device or network element in your network to ensure optimum performance and security. This includes real-time network traffic monitoring and passive monitoring with historical data.
Using the right tool to monitor network traffic is the most crucial step in enterprise network traffic monitoring. A powerful tool not just monitors bandwidth usage but keeps track of every activity in your network, and helps identify who is using your network, how much, when, and why.
Traditional and free network traffic monitoring tools for Windows analyze using hardware probes or packet analyzers to offer granular and detailed information on network traffic. However, hardware probes require complex deployment procedures, and typically do not account for IP security (IPsec) traffic.
On top of this, packet analyzers flood you with results that do not offer direct insight into application-specific traffic in the network. As a result, the IT department faces an increased troubleshooting cycle, and takes a lot of time to make critical decisions affecting the network.
While firewalls and intrusion detection systems are important for network security, a network traffic monitoring tool that monitors your network closely at all time and identifies anomalies in network traffic patterns is what helps completely secure your network.
Optimizing your network involves overall performance optimization to prevent bandwidth hogs, optimation using network forensics to identify and drill down to root cause of specific issues in your network that cause latency and jitter resulting in poor voice and video communication, and optimizing your network using QoS to ensure mission-critical apps are prioritized.
Today with Cisco’s NetFlow innovation (and other flows from other vendors), ManageEngine's real time network traffic monitoring tool takes far less time and effort, and yields better results to the enterprise. NetFlow Analyzer continuously collects granular details on IP traffic without affecting device performance or increasing the costs.
Using this exported NetFlow data, ManageEngine NetFlow Analyzer gives network administrators/managers the visibility they need to understand the WAN. Armed with powerful instant reports on top talkers, conversations, and more, this network traffic monitor tells IT teams exactly what they need to know in order to troubleshoot or make informed capacity planning decisions.

NetFlow Analyzer is a web-based network traffic monitoring tool that analyzes NetFlow exports from Cisco routers to monitor network traffic metrics including traffic volume, traffic speed, packets, top talkers, bandwidth utilization, and high usage times.
There are various reports that can be obtained from NetFlow Analyzer. This network traffic monitoring software is easy to deploy and work with. You can install NetFlow Analyzer on a Windows or Linux machine, and use a web browser to access the client interface. After installation, set up your Cisco routers/switches to export NetFlow data to NetFlow Analyzer. Within minutes, traffic graphs are plotted and reports are automatically generated, and you are all set to monitor traffic in your network.
Exporting flows in NetFlow Analyzer is an effortless process and can be done in a single click. NetFlow analyzer acts as an advanced network usage monitor, giving you an overview of your network's bandwidth usage statistics and inventory at a glance via it's customizable dashboard as soon as the devices are discovered. Users can then drill down into the interfaces to view network traffic and information on the traffic, application, source, destination, conversation, differentiated services code point (DSCP) and quality of service (QoS) of the traffic. Detailed reports with one-minute granularity can be generated based on these critical data parameters.
ManageEngine NetFlow Analyzer is a web-based real-time network traffic monitoring tool used by more than 4,000 enterprises that analyzes NetFlow exports from Cisco routers to gain in-depth information about network traffic, including traffic volume, top talkers, bandwidth consumption, and high usage times.
The information provided by NetFlow Analyzer helps IT teams with:
NetFlow Analyzer is a network traffic monitor software for Windows and Linux and is a NetFlow, sFlow, jFlow, and more collection and analyzing engine integrated together. As a real-time network traffic monitoring software, it helps you monitor bandwidth utilization and makes network traffic management easier and more efficient. This traffic monitoring tool does not require any hardware probes and can be downloaded, used in your network environment, and evaluated free for 30 days.
