SolarWinds NetFlow Traffic Analyzer is designed to allows users to monitor network bandwidth and traffic patterns in real time and over time. How does the NetFlow analyzer work in NTA?.Using a NetFlow analyzer to understand traffic flow data can help you better determine causes of bottlenecks and overall traffic volume, both of which play an important role in capacity planning and ensuring resources are adequately provisioned and properly allocated as an organization scales. Analysis applications are responsible for analyzing the flow data received from flow collectors for signs of intrusion or malicious traffic profiles. Flow collectors are responsible for receiving, storing, and preparing flow data from flow exporters for processing. A flow exporter is responsible for aggregating data packets into flows and exporting records of those flows towards flow collectors. These include a flow exporter, a flow collector, and an analysis application. There are three primary components to a Cisco NetFlow analyzer monitoring system. Manually performing traffic analysis across different data types can be a time-consuming process typically requiring multiple tools to gain different metrics, normalize this data, and create a consolidate view. Reference Documentation: Flexible Netflow Configuration Guide for IOS Release 15.Cisco NetFlow analyzers are designed to offer more functionality than simple packet and byte aggregation solutions, which includes providing greater insights into traffic and supporting faster troubleshooting with comprehensive data correlation features. show flow record - Displays information about NetFlow flow records.p - Displays the contents of the cache for the flow monitor, in the format specified.
Flexible NetFlow allows you to define an optimal flow record for a particular application by selecting the keys from a large collection of predefined fields. NX-OS supports the Flexible NetFlow feature that enables enhanced network anomalies and security detection. In this post, I'll go over NetFlow configuration on NX-OS and IOS Catalyst switches NX-OS Flexible Netflow Configuration for 7.x: This is a continuation of my previous post.
