The Details on NetFlow and Why it’s Important
Effectively monitoring and managing your network can be complicated, and there is generally more than a few aspects of the network that need to have an eye kept on them. One thing that is becoming increasingly important in proper network monitoring is monitoring your network’s NetFlow. Of course, it is important to really understand what NetFlow is and exactly why it is so important to monitor this within your network.
Ok so, first things first, what is NetFlow exactly? Well, in technical terms, NetFlow is a Cisco developed technology that provides statistical information on traffic passing through NetFlow enabled devices like top hosts, protocols, applications and conversations.
Basically, NetFlow gives you in-depth insight into how your network is performing. (Yes, this means that during March Madness, your company’s network managers were well aware of everyone who was streaming live games during the opening two days of the tournament.) It allows network managers to collect comprehensive information about their network’s performance and how the bandwidth is being used, making it easy to identify, view and report on the details of its utilization. By implementing a NetFlow monitoring tool into your network management strategy, you gain the ability to expand upon your efforts and begin monitoring your network’s performance, network planning, performing security analysis, analyzing traffic and bandwidth utilization, monitoring users and a number of other things.
Obviously, being equipped with the knowledge of the technology is a good way to approach monitoring the many aspects of your network effectively, however you also need to employ the efforts of the proper tools.
