" 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. "

"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 Linuxmachine, 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 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.
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.
As a network manager you need to be on top of your network to be in control of the day-to-day happenings in your network. Especially, with more and more businesses being increasingly dependent on the internet, it is very vital that you are in total control of your network.Any network outage has to be quickly attended to and fixed right away. More importantly any network incidents has to be pro-actively attended to. NetFlow Analyzer with its proactive alerting mechanisms ensure that you are informed of any network exceptions as it happens. Also the drill down features let you quickly pin down the cause of any network problems and troubleshoot faster.
It is also very essential that you ensure your business critical applications are not starved off bandwidth while non-critical activities like music downloads hog the available bandwidth. By giving you an indepth visibility in to your network and the bandwidth usage statistics you can appropriately set QoS policies. It is also possible to categorize applications that consume bandwidth by port, protocol and IP address. This way you can be fully empowered to ensure that the business critical applications always have the required bandwidth.
As a network administrator you need to have all the reports to take the right decision. Especially when it comes to bandwidth capacity planning decisions the stakes involved are high and even a small mistake can cost huge money. NetFlow Analyzer with its long range historical reporting lets you take the right decisions. Also as a network administrator you need to have periodic reporting to understand how the network is performing. NetFlow Analyzer's automatic report generation feature at scheduled time periods help you with just that.
Should you need any specific information at any point in time, you could just access the application for a quick snapshot. NetFlow Analyzer's dashboard presents you with all the vital metrics you need to be aware of as an administrator. You could drill down on it for any further information on any specific element of your network.
