NetFlow Analyzer: Introduction

     

    ManageEngine ™ NetFlow Analyzer is a web-based bandwidth monitoring tool that performs in-depth traffic analysis using data exported from NetFlow™ / Netstream™ / cflowd™ / J-Flow™ / sFlow™ / IPFIX™/ AppFlow flows.

    This data provides granular details about network traffic that has passed through an interface. NetFlow Analyzer processes this information to show you what applications are using bandwidth, who is using them, and when. Extensive graphs and intuitive reports make this information easy to analyze, and also help accelerate the troubleshooting process.

    NetFlow Analyzer comes pre-loaded with a set of features that provide in-depth bandwidth usage statistics and let you drill down to see more details about a bandwidth traffic, application, or conversation etc. NetFlow Analyzer also includes other administrative options that help in managing enterprise networks and bandwidth utilization with ease.

     

    Why NetFlow Analyzer?

    ManageEngine NetFlow Analyzer comes with out of the box high performance API driven UI and highly scalable capabilities, including the following key features:

    • Support for multiple flow exports

    Regardless of different types of flows, now you can view a complete picture of the usage, network performance, and traffic statistics of various network devices in single console. Support's NetFlow version 5 , version 7 , version 9,  IPFIX, jFlow, sFlow, Netstream, Appflow etc.

    • Web-based API driven UI

    View the status of your links, and generate reports from just a web browser that is built on a JavaScript framework powered by Ember.js. This new Fluidic web client offers 10x more productivity and performance compared to the previous UI. The new user interfaces also features keyboard navigation across interface snapshot pages, alarms and performance graphs which helps network admins to access the information they are looking for even more quickly and easily.

    • Real-time Traffic Graphs

    View instant graphs for bandwidth utilization and traffic per link up to previous minute.

    • Historical Trend Reports

    Generate daily, weekly, monthly, and custom time period bandwidth reports showing peak traffic patterns from the day 1.

    • Application-level QoS shaping

    Reconfigure application QoS with ACL to filter application traffic, thus reserve bandwidth for mission critical activities. Now you can shape app traffic via service policy and allocate % to particular application and thus regulate the bandwidth usage with the help of CBQoS monitoring. 

    • Cisco Application Visibility and Control (AVC)

    Provides an detailed information from Cisco ASR1k and ISR-G2 routers with information on NBAR2, Application response time, QOS Hierarchy, HTTP URL reporting.

    • Cisco class-based Quality of service monitoring (CBQoS)

    Validate the effectiveness of your QoS policies using CBQoS reports from NetFlow Analyzer. Prioritize your network traffic accordingly.

    • High Scalability

    Now, NetFlow Analyzer can scale up to 250K flows per second without raw data storage and with raw data storage it can process upto 100k flow per second.

    • Capacity Planning & Billing

    Helps you accurately measure your bandwidth growth over a period of time and helps to anticipate the changes in bandwidth with capacity planning reports. You can also generate on-demand billing for accounting and departmental chargebacks.

    • Network Forensics & Security Analysis

    Advanced security analytics module helps to detect a broad spectrum of external and internal security threats and categorize threats/anomalies as problems such as Bad Src-Dst, DDoS, Suspect Flows.

    • Traffic Profiling

    View bandwidth reports based on top applications, top hosts, and top conversations, DSCP, multicast.

    • Consolidated Reports

    View bandwidth reports per Device and interfaces, showing top applications,  top talkers in a single report.

    • Device Grouping

    Categorize NetFlow devices into logical groups and grant reporting access to specific users based on hierarchy. Group IP addresses and address ranges into department wise , and monitor bandwidth usage individually.

    • Traffic Configuration & User Management

    Identify most standard applications out-of-the-box and configure custom applications and monitor the same. Add users with different privileges, assign device groups, and selectively allow access for monitoring and reporting.‚Äč
