Flowmon

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.

Last year completely refuted doubts about the increasing cyber security risks. Hackers, obtained sensitive data on hundreds of German politicians, including Chancellor Merkel and accessed data relating to tens of millions of Facebook accounts. The year also confirmed that hacking has become a means for political activists and an effective tool for professional criminals who have discovered a lucrative opportunity on the internet. What conclusions can we draw from these events for 2019?

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.

Did you know you can create logs with any flow information and export it to 3rd party systems like SIEM. Check this post to see how to do it and what we have prepared for you.
