This work has been done as an assignment from CGI with the ambition to find an opensource program that provides both network monitoring and performance testing. Theprogram should be able to run on a portable server or other machine, to allow for datagathering of one network one day and of another network the next day. Due to the currentstate of society all work is done *remotely*, restricting tests to only be performed onsmaller private networks. Much time is put into research to find the programs that intheory would work for the purpose. It's quickly revealed that with open source as ademand, a single program is not an option, thus the search is expanded. Tests areperformed where the programs are graded by useability and functions that facilitateredeployment of the server between network sites. The results for network monitoring arethe programs OpenNMS Horizon and NetXMS, which both lived up to the demands. Theprogram chosen for performance testing is Flent, which among others combines Iperf andNetperf in its tests and presents the results in graphs.The limited time affected ouropportunities to test all the programs we came across and the current pandemic limitedour opportunities to test our chosen programs to a greater extent.The goal of finding onesolution was not accomplished and instead resulted in two separate pieces of software.These are found to accomplish their respective goals.
