NetFlow Analyzer

Bandwidth Monitoring & Traffic Analysis

What is NetFlow Analyzer?

  • A web based (no hardware probes), bandwidth monitoring, network forensics and network traffic analysis tool
  • An integrated NetFlow, sFlow, JFLow (and more) collector, analyzer and reporting engine
  • Optimizes networks for peak performance
  • Gives in-depth visibility into network traffic and its patterns, and how this impacts the overall health of the network

NetFlow Analyzer. Your Solution.

Network Traffic Analysis

NetFlow Analyzer is a web-based network traffic analyzer using NetFlow from Cisco devices to generate instant reports on network traffic and users. Cisco NetFlow offers granular and accurate details on applications, users, and conversations generating traffic on the network.

  • Real-time traffic reports for each WAN link
  • Application analysis for traffic
  • Historical traffic analysis
  • Traffic analysis summary

Network Bandwidth Monitoring

Network bandwidth monitoring is one of the most critical activities of an enterprise network administrator. NetFlow Analyzer provides several instant reports to monitor bandwidth including top talkers, top protocols, top conversations, and more.

  • Threshold Based Alerting
  • Bandwidth Monitoring without Probes
  • Real-time Bandwidth Monitoring
  • Historical Bandwidth Usage Trends
  • Application-wise Bandwidth Distribution
  • Consolidated Bandwidth Usage Summary

Protocol & Application Monitoring

In this age when more and more applications and services are being delivered across the network, the efficiency of your network defines the productivity of your organization. Applications, such as voice, which are critical for your corporate communication need to be provisioned the highest priority on your network. Application/Protocol monitoring:

  • Network administrators (users) can see which applications are being used in the network
  • Bandwidth consumed by each applications is known
  • Application mapping - Enterprise specific applications can be mapped as per the user's need
  • Application grouping - Ability to group certain applications as per users requirement for ease of monitoring
  • The ability to map applications based on port, protocol and IP Address / network
  • Distribution of protocols can be viewed with ease

NetFlow Monitoring

NetFlow Analyzer is a netflow monitoring tool which collects NetFlow packets or other supported flows exported from enterprise routers and switches, generating network traffic reports that help understand the nature of the network traffic and the bandwidth utilization, thus helpful in traffic analysis and bandwidth monitoring.

  • Fast troubleshooting
  • Validating QoS policies
  • Scheduled reports
  • Alert profiles
  • IP Grouping
  • Application mapping
  • Device grouping
  • Role based access
  • Flexible licensing

You & NetFlow Analyzer. Your Benefits.

In-Depth Traffic Analysis

Without using hardware probes or appliances, NetFlow Analyzer makes traffic analysis both simple and effective. Apart from setting up your routing/switching devices to export NetFlow data to NetFlow Analyzer, no further configurations are necessary. NetFlow Analyzer uses NetFlow®, sFlow®, cflowd®, J-Flow®, IPFIX®, NetStream® and Cisco NBAR® to show top applications, top hosts, and top conversations using bandwidth. This information is vital in understanding peak hour usage and historical trends, and in the long run, aid in bandwidth capacity planning and enforcing security policies.

Simplified Bandwidth Monitoring

In most enterprises, unmanaged bandwidth leads to inappropriate applications taking priority over critical business applications during peak hours. Bandwidth reports in NetFlow Analyzer shows you exactly what applications have been utilizing the bandwidth during peak hours, and lets you drill down to see the top hosts using those applications. This helps in controlling bandwidth usage and enforcing better policies across the enterprise. NetFlow Analyzer becomes a very affordable alternative to enterprises that need to monitor bandwidth usage, but do not want to invest in expensive WAN monitoring and bandwidth management solutions.


Alerting Based on Thresholds

NetFlow Analyzer generates alerts, and sends you an email when the traffic utilization exceeds pre-defined threshold settings. It also forwards SNMP traps to NMS / EMS application for critical alerts in the network. This helps is quicker fixing of the problem in the network.

Departmental Bandwidth Usage

Allows you to create departments / divisions based on IP addresses, with options to filter based on application and interfaces. You can then view bandwidth usage statistics for a particular IP group . This NetFlow analyzer helps in reporting bandwidth costs and accounting based on department wise bandwidth usage.


Custom Reports

NetFlow Analyzer is an active tool, which not just monitors but delivers effective reports. The reporting feature in NetFlow analyzer lets you select specific parameters to report on. For example, you can view bandwidth used by a specific host or network, to access a single application during a certain week. Such options give greater flexibility in meeting your bandwidth monitoring needs.

Reduced Operational Costs

NetFlow Analyzer reduces costs by simplifying management tasks. Troubleshooting takes far less time than with packet analyzers that require more time to analyze results and come to conclusions. Bandwidth reports and drill down options make traffic analysis faster and more efficient, thereby effectively using key resources in the enterprise.


Reduced Training Costs

NetFlow Analyzer reduces training costs by providing a simple and user-friendly web client to perform all operations. It also includes an embedded MySQL database to store the Flow data, thereby saving administrators from the hassles of working with multiple packages and ensuring compatibility between them.

QoS validation using Cisco CBQoS

To ensure that the business-critical applications receive the highest priority on your network, network administrators can implement QoS policies and fine tune them using Cisco CBQoS technology which is readily supported by NetFlow Analyzer. Using NetFlow Analyzer you can see the policies applied to various interfaces and you can validate these QoS policies by monitoring the pre-policy and post-policy status in different traffic classes.


Effective Data Storage

Data is stored in both aggregated and non-aggregated formats. The aggregated top 100 is stored forever and provides reports for capacity planning and long term reporting. The non-aggregated (or raw) data can be stored for up to 1 month and allows troubleshooting with 1 minute granularity.

Completely Web-Based

NetFlow Analyzer is completely web-based, which makes it easy to view traffic reports across WAN links from anywhere on the network using just a web browser. NetFlow Analyzer runs in both Windows and Linux.

"NetFlow Analyzer has helped us reduce the time taken to isolate and contain threats like worms and virus attacks. It has also helped us to solve network incidents faster, and do better capacity planning."

Fred Hassard, Adventist Health


"It has helped identify our biggest bandwidth abusers and malicious applications running on the network. It also has an easy interface to see the network stats on our different locations. "

Nick Rieber, Glenbard High School District 87

"We have been using NetFlow Analyzer for the purpose of monitoring the bandwidth consumption across the school network spread around 35 sites at Elizabeth, NJ. We have found the product very helpful in capacity planning and in bandwidth related troubleshooting. I would recommend NetFlow Analyzer to anyone looking for a bandwidth monitoring solution."

Girish Kumar, Elizabeth Board of Education
