Growing network needs complicate the job of network administrators and bring in new challenges. Network Administrators need robust,cutting-edge network management tools to quickly troubleshoot network incidents and increase the network performance. However considering the economic situation, it is very important to choose the right application which can leverage on network performance management data from multiple technologies and of course at an affordable cost.
ManageEngine NetFlow Analyzer team constantly interacts with its customers, technology companies and VARS to prioritize the road map. Whenever a new technology is introduced in the product, all existing customers see an immediate value by means of simple free upgrade instead of paying a hefty price. Here the ROI includes cutting bandwidth upgrade costs due to increased visibility using ManageEngine NetFlow Analyzer, avoid unauthorized bandwidth usage and increase the efficiency of business critical applications with almost zero implementation cost.
Multiple technologies – Single Solution:
Cisco NetFlow:
Cisco’s NetFlow technology exports flow records from any IOS capable routers and switches. The exported flow records contain information about protocols, ports, source, destination IP addresses and much more.
NetFlow Analyzer provides several instant reports to monitor bandwidth including top talkers, top protocols, top conversations, and more. Apart from these pre-defined bandwidth reports, NetFlow Analyzer also includes options to search for specific bandwidth usage details based on IP address, host name, protocol, and more.
Bandwidth Monitoring without Probes
NetFlow Analyzer does network bandwidth monitoring using NetFlow. NetFlow exports are collected, correlated, and analyzed to get granular details to monitor bandwidth usage across each WAN link. There is no need for hardware probes to monitor bandwidth usage. NetFlow Analyzer is an all software solution which is suitable for both Windows and Linux.
Real-time Bandwidth Monitoring
Bandwidth monitoring reports for each interface shows the current, average, and peak bandwidth usage patterns across each NetFlow-enabled interface. With these bandwidth usage statistics you can get instant visibility into how much bandwidth was used up by hosts, applications, and conversations across a specific interfaces.
Application-wise Bandwidth Distribution
To monitor bandwidth utilized by different applications, NetFlow Analyzer gives you instant visibility into which applications are using up maximum bandwidth. You can also drill down to see the top sources, destinations and conversations using the bandwidth. With such granular detail, network troubleshooting and problem resolution take far less time than with traditional tools.
Cisco NBAR:
Cisco NBAR (Network Based Application Recognition) engine runs on the IOS and does deep packet inspection to identify applications riding on regular ports. For example TCP 80 can be identified as kazza2, BitTorrent, Napster etc. The respective utilization, volume and speed can be polled through SNMP protocol over time.
NBAR reports are very useful to set the Quality of Service (CB-QoS) policies. NBAR and QoS policies can work together to prevent bandwidth stealing applications and increase the efficiency of business critical applications.
Cisco CB-QoS (Class Based – Quality of Service):
We have discussed a lot about deploying CB-QoS policies for improved network performance. You can find CB-QoS blog series in this link. Cisco CB-QoS is the simplest way to prioritize network traffic.
Having insights over pre and post policy metrics, network administrators can modify their CB-QoS policy configuration for improved performance and to avoid any impact to business critical applications due to misconfiguration.
This is why we call ManageEngine NetFlow Analyzer is a powerful traffic analysis and forensic solution for a network of any size. Try our 30 days all feature version and write your queries to netflowanalyzer-support@manageengine.com
