Using basic network performance metrics, namely Round Trip Time (RTT) and Server Response Time (SRT), is an easy-to-go way how to deal with performance issues in your network. Let’s take a closer look at how every network administrator can use RTT and SRT metrics in Flowmon.
In my 20+ years career, I’ve worked with two types of technologies. Those that took extensive marketing efforts to communicate their value and failed to deliver it, as well as technologies that proved themselves quickly during a single day. Network performance monitoring using flow data is the second case. In this post, I share my experience with NPM techniques, how to take them on in a real environment and what are the typical root causes of performance bottlenecks found in network traffic.
