This report is the result of a thesis project performed in cooperation with a local company inSkellefteå named Sherpas. They help other companies and organizations with businessand system-development and project management, etc.As an IT-company today it is important to have an overview of the company's network toavoid outside intrusion or unnecessary bandwidth-thieves from within. With a good programfor network monitoring these two problems, and much more, can be fixed. In this report threevarious programs are tested and evaluated. One program is free of charge, one costs andthe last program is open source. All three of these programs are based on NetFlow as acollector of network traffic.The test is performed on a server which is reached via remote desktop. On the server threehyper-V machines are installed for performing the tests on. Much of the work is also basedon reading into and understanding the programs and what their strengths are.The programs that will be tested are Solarwinds real-time netflow analyzer FREE-tool,solarwinds NetFlow traffic analyzer which costs after 30-days evaluation and the opensource program ntopng with nProbe.The results show that all three programs work well for the purpose. The free program is, asexpected, very simple in both installation and ease of use. There is a lack of functions thatthe other programs have and the 1 hour time-limit on captures is a big minus, but it is still agood program. The other two programs were somewhat more complex in both installationand ease to use with ntopng being a little bit easier to understand if you just compare thosetwo.Some unexpected problems with the open source program ntopng occured. The mainprogram ntopng is open source as expected, but not nProbe which is a big part of the testsince it is the NetFlow collector. But I could still evaluate the program's interface, ease to useand installation process.The time limit that I had to make this work played a major role in the outcome, but is still abeginning to see what is important in a program for the specific purpose.
