A Look at Network Monitoring
by Russell Kirkland and Luis Abreu Corning Optical Communications
If you’ve invested tens of millions of dollars in building a reliable, robust, and high-performance network system, you need to now ask yourself some serious questions: what will you do in order to ensure higher performance, improved reliability, and better utilization of your network? Will you be proactive, or will you react when your system starts to lag and switch over-utilization begins crashing critical applications? Is gambling with your system worth the cost to you, your customers, and your reputation?
The answer to all of these questions is network monitoring. Many people immediately think of security applications when they hear the term network monitoring. However, while network monitoring does include the ability to analyze potential security threats like denial of service attacks and hackers, it can also be used by network administrators to monitor real-time performance of their network and identify bottlenecks or other potential performance issues. Monitoring done correctly should allow you to see error, performance and utilization data, and ensure the accuracy of changes, validating that they only produce desired results. This means that you can set a baseline of application performance before migrating or consolidating data center components, monitor performance throughout the move, and then optimize the new system for maximum utilization, availability, and performance. Currently, some of the world’s leading financial institutions, large commercial SANs, and most innovative consumer companies utilize the benefits of this preventive approach to realize a return on their investments in months rather than years.
