Opmanager Network Traffic Ananalysis

In–depth network visibility using flow–based traffic analysis
With traditional SNMP–based monitoring you don’t get visibility into who or what applications are using that 15 GB of OUT traffic.

Network traffic analysis & troubleshooting with the NetFlow Plug–in
OpManager leverages flow–based network traffic analysis to show you how exactly your bandwidth is being utilized through interface–specific reports on which user, application, source, destination, conversation etc is occupying bandwidth. With the NetFlow plug–in you can now:

Gain in–depth information on network traffic composition
Use Cisco NBAR to identify bandwidth–consuming applications such as Skype
Troubleshoot bandwidth spikes, DoS attacks, network slowness etc. over LAN and WAN
Validate effectiveness of your network QoS policies using Cisco CBQoS
Make important capacity planning decisions aided by months of traffic trends gathered
Have your own bandwidth billing system to crosscheck on ISP charges

The NetFlow plug–in is available as a separate downloadable file to be installed over OpManager, enabling both collection and analysis of various flows such as netFlow, JFlow, SFlow e.t.c..

Gain in–depth information on network traffic composition
Know what your network traffic is comprised of through reports on top applications, hosts, protocols, DSCP etc. for every link and for any configurable IP based group. You can analyze your network traffic over multi–vendor routers and switches through the NetFlow Plug–in. Supported network protocols include NetFlow^® version 5, 7 and 9, sFlow^®, cflowd^®, jFlow^®, IPFIX^®, NetStream^® and Cisco^® NBAR technology.

Use advanced application recognition
The NetFlow Plug–in’s ability to map applications by combining IP Address, Port and Protocol enables you to know in detail about your applications using the network bandwidth. Further, you can also identify applications (e.g. Skype) that use dynamic ports using Cisco’s Network Based Application Recognition (NBAR) and ensure that these do not consume huge bandwidth.

Did you know?

You can also disable switch ports through OpManager. So once you identify the host causing the traffic jamming, you can get into the switch monitoring dashboard in OpManager and from there disable the port connected to the troubling host.

Troubleshoot bandwidth problems
The NetFlow plug–in supports custom application mapping which helps you extract accurate network traffic utilization reports. You can know exactly what applications have been using bandwidth and for how long, you can also further drill–down to see the top hosts using those applications. In ase of worms, virus or Denial–of–Service (DoS) attacks, the NetFlow plug–in facilitates quick problem isolation and resolution to bring down your Mean Time To Resolve.

Validate network QoS policies
The Cisco CBQoS add–on helps you qualify the QoS policies set on the router and ensure that the right type of traffic gets priority in the network. By studying the traffic composition at pre–policy and post–policy together with the resultant dropped traffic, you can easily judge effectiveness of the implemented QoS policy.

Make important capacity planning decisions
The NetFlow plug-in allows you to create powerful custom reports to analyze bandwidth usage trends in detail e.g. bandwidth used by a specific host/ network accessing an application during a particular week. By creating IP address based departments / divisions and filtering based on applications and interfaces, you also get critical inputs for enterprise bandwidth capacity planning.

Have your own bandwidth billing system
You can now rest your suspicions of being overcharged by cross–checking ISP charges with your own billing system available with the Billing add–on. You can also associate bandwidth costs to each department in your organization to help you plan well with allocated bandwidth budgets. The Billing add–on over the NetFlow plug–in helps you to account your bandwidth by assigning costs to usage (volume–based) or bandwidth (speed–based).
