In most enterprises, unmanaged bandwidth leads to inappropriate applications taking priority over critical business applications during peak hours. Bandwidth reports in NetFlow Analyzer shows you exactly what applications have been utilizing the bandwidth during peak hours, and lets you drill down to see the top hosts using those applications. This helps in controlling bandwidth usage and enforcing better policies across the enterprise. NetFlow Analyzer becomes a very affordable alternative to enterprises that need to monitor bandwidth usage, but do not want to invest in expensive WAN monitoring and bandwidth management solutions.
Without using hardware probes or appliances, NetFlow Analyzer makes traffic analysis both simple and effective. Apart from setting up your routing/switching devices to export NetFlow data to NetFlow Analyzer, no further configurations are necessary. NetFlow Analyzer uses NetFlow®, sFlow®, cflowd®, J-Flow®, IPFIX®, NetStream® and Cisco NBAR®to show top applications, top hosts, and top conversations using bandwidth. This information is vital in understanding peak hour usage and historical trends, and in the long run, aid in bandwidth capacity planning and enforcing security policies.
To ensure that the business-critical applications receive the highest priority on your network, network administrators can implement QoS policies and fine tune them using Cisco CBQoS technology which is readily supported by NetFlow Analyzer. Using NetFlow Analyzer you can see the policies applied to various interfaces and you can validate these QoS policies by monitoring the pre-policy and post-policy status in different traffic classes.
NetFlow Analyzer generates alerts, and sends you an email, when the traffic utilization exceeds pre-defined threshold settings. It also forwards SNMP traps to NMS / EMS application for critical alerts in the network. This helps is quicker fixing of the problem in the network.
Allows you to create departments / divisions based on IP addresses, with options to filter based on application and interfaces. You can then view bandwidth usage statistics for a particular IP group . This NetFlow analyzer helps in reporting bandwidth costs and accounting based on department wise bandwidth usage.
NetFlow analyzer is an active tool, which not just monitors but delivers effective reports. The reporting feature in NetFlow analyzer lets you select specific parameters to report on. For example, you can view bandwidth used by a specific host or network, to access a single application during a certain week. Such options give greater flexibility in meeting your bandwidth monitoring needs.
NetFlow Analyzer reduces costs by simplifying management tasks. Troubleshooting takes far less time than with packet analyzers that require more time to analyze results and come to conclusions. Bandwidth reports and drill down options make traffic analysis faster and more efficient, thereby effectively using key resources in the enterprise.
NetFlow Analyzer reduces training costs by providing a simple and user-friendly web client to perform all operations. It also includes an embedded MySQL database to store the Flow data, thereby saving administrators from the hassles of working with multiple packages and ensuring compatibility between them.
Data is stored in both aggregated and non-aggregated formats. The aggregated top 100 is stored forever and provides reports for capacity planning and long term reporting. The non-aggregated (or raw) data can be stored for up to 1 month and allows troubleshooting with 1 minute granularity.
NetFlow Analyzer is completely web-based, which makes it easy to view traffic reports across WAN links from anywhere on the network using just a web browser. NetFlow Analyzer runs in both Windows and Linux.
