How does NetFlow collection work in NTA?.Since network collectors can correlate data metrics by IP address, protocol, or port, this can also enable faster insights into how different network components interact and are affected by flow patterns to help teams pinpoint which devices and services are bottlenecks on the network, in addition to more easily uncovering the root cause of a traffic slowdown. NetFlow collectors can streamline the process by gathering traffic packets from one or more data sources, and efficiently normalizing and consolidating this information, so it’s organized and usable for analysis. Manually performing NetFlow traffic analysis can be inefficient, requiring more time to produce results with far less accuracy and granular specificity.

Using NetFlow collector software can also significantly increase the efficiency of network operations. Sudden spikes, drop-offs, and other anomalies in network traffic and flow patterns could be signs of serious security problems like network breaches. NetFlow collection can also contribute to improving network security by enabling teams to more easily detect potential issues.
Upgrading systems and provisioning additional resources can be a significant undertaking, and proper collection and analysis of flow information can provide the empirical data showing the need for additional ports and interfaces capable of sustaining higher bandwidth as demand increases. Understanding NetFlow is also beneficial for capacity planning and scaling network resources to support additional traffic. This provides network and security teams with insights about which users are the top talkers, which applications are being accessed most frequently, and whether particular end users are hogging an inordinate proportion of network resources. NetFlow collector software is a foundational part of network monitoring strategies, as these tools provide the data used to generate easy-to-understand visualization of top-down views of overall network traffic. Altogether, this combination of tools and services can help you streamline your network and security monitoring strategies for greater efficiency and effectiveness. NetFlow collectors can also correlate flow data, making them a necessary part of troubleshooting problems related to network traffic across devices. NetFlow collector software plays a critical role in the NetFlow monitoring and analysis process, making it possible for you to gain deeper understandings of network flow, traffic, and bandwidth consumption.Ĭollecting flow traffic data is the first step to gaining the visibility and actionable insights to allow more effective management of users, applications, devices, and services on a network. In distributed or high-traffic networked environments, flow collectors can be likewise distributed for more comprehensive data collection, but each of the collectors will need to be configured to send the data to a centralized server for analysis.
A NetFlow collector is part of a flow monitoring system designed to receive, process, and store IP traffic data packets from these network devices. NetFlow is a protocol developed by Cisco Systems used to record statistical, infrastructure, routing, and other information about traffic flows passing through a NetFlow-enabled router or switch.
