ManageEngine NetFlow Analyzer is a web-based traffic analysis tool that helps network managers to understand how bandwidth is being used up in their network. Leveraging the level of granularity provided by Cisco’s NetFlow technology, NetFlow Analyzer lets you see what applications are using bandwidth, who is using bandwidth, and when.

Understanding Network Performance Problems

Performance problems on the network don’t always warrant an increase in bandwidth. When a link becomes slow, you want to find out what’s causing the bottleneck, which hosts are eating up resources, and for how long the link has been slow. Without fine-grained information on the traffic that is flowing in and out of your network, you may never find out the root cause of such problems. You will simply re-route traffic through another link, or request for more bandwidth.

• How can you determine what’s wrong before users start complaining?
• Where will you search to find the culprit who’s hogging bandwidth?
• How will you decide if you need more bandwidth?

NetFlow Analyzer helps you answer these questions and more. With instant reports on every host, application, and conversation across your network, troubleshooting is a lot easier, and takes far less time. Traffic graphs over varying time periods show you bandwidth usage trends, and traffic patterns across hosts, applications, and conversations. Informative pie charts show you at one glance, what percentage of the total bandwidth is used up by each source, destination, and application.

Such information ensures accurate choices for the entire enterprise regarding capacity planning, network auditing, and traffic management.

What can NetFlow Analyzer tell you?

1. Capacity Planning
   
   NetFlow Analyzer can tell you if available bandwidth is being utilized effectively. With in-depth information on protocols, hosts, and applications that are using maximum bandwidth, NetFlow Analyzer instantly points you to links that are experiencing problems.


2. Troubleshooting

   NetFlow Analyzer offers real-time identification and monitoring of unwanted traffic. If a virus has been identified on the network, you can quickly identify which hosts and links have been affected. In this way, NetFlow Analyzer is a very effective network troubleshooting tool.

3. Traffic Analysis

   Understanding network traffic boils down to answering the who, what, when, where, and how of bandwidth usage.

   • The who, what, when, where, how of bandwidth usage
   • Traffic trends and peak-time usage patterns

NetFlow Analyzer Features

• Measure traffic by rate, volume, and utilization by protocol, host, and conversation
• Real-time reports for every interface on the network
• Identify custom applications using a combination of ports and protocols
• Customize time periods to observe workday reporting
• View reports across subnets and IP address ranges
• Categorize links into different groups and selectively allow access

Standard Reports

• Host-wise and application-wise bandwidth usage reports
• Interface-wise reports with consolidated traffic details
• Traffic rate, utilization, and volume for applications, hosts, and conversations
• Historical reports with daily, weekly, monthly, and quarterly traffic utilization graphs

Custom Reports

Custom reports allow you to fine tune traffic details, and view only the data that you want to see. For instance, you can create reports based on:

• Specific time periods
• Specific network, or range of IP addresses
• Specific application, host, or conversation
• Incoming and/or outgoing traffic
