Monitor Bandwidth with NetFlow

"Before… We had slow links and the boss breathing down my neck. I had nothing but a real-time free sniffer. Now I have a huge advantage and “freedom” to see what’s going on by the minute, hour, week…. It’s completely awesome. Thanks ManageEngine for creating such an easy program to deal with, solid and robust"

NetFlow Analyzer is a web-based tool that analyzes and monitors bandwidth usage across the enterprise. Different routing/switching devices export different flow, NetFlow Analyzer does network traffic analysis by analyzing NetFlow / sFlow / jFlow / IPFIX / NetStream. The flows are collected and correlated by NetFlow Analyzer in order to generate reports on bandwidth utilization, top talkers, top applications, top bandwidth users, and more.

NetFlow Analyzer is very simple to deploy and start working with. NetFlow Analyzer can be installed on a Windows or Linux machine, and use just a web browser to access the client interface. After installing, set up your Cisco routers/switches to export NetFlow data to NetFlow Analyzer. Within minutes, traffic graphs are plotted and reports are automatically generated by NetFlow Analyzer. NetFlow Analyzer also leverages on the Cisco NBAR and Cisco CBQoS technology to help the network administrators validate their QoS policies.

Bandwidth Monitoring Features in NetFlow Analyzer

Real time Bandwidth Report
Real-time Bandwidth Reports for each WAN link

As soon as NetFlow data is received, graphs are generated showing details on incoming and outgoing traffic on the link for the last 10 minutes.

Application-wise Bandwidth Distribution

Application reports show the top applications using up bandwidth. From here you can drill down to see the top hosts and conversations for each application that is listed.

Top Bandwidth Users
Historical Bandwidth Usage Trends

Traffic trends and user trends help identify peak usage hours, link utilization metrics, and more. You can also view trends of application usage, protocol usage, and more.

Bandwidth Usage Summary Reports

Consolidated reports show you overall bandwidth usage statistics for each WAN link. You can view current bandwidth usage patterns, along with details on hosts, applications, and conversations using up bandwidth.
