Having dealt with system designs and issues throughout my career, I always felt the need to quickly create and perform benchmark tests on Linux systems. I have finally released a Python tool to accomplish that task. PyMergen is a configuration-driven test automation tool for Linux. It is intended to be a local command executor to automate repetitive and iterative testing actions on a Linux host to perform benchmarking and metric collection. The default collection logic is built around Linux Control Groups (cgroups) and Perf tools, and the functionality is extensible through a plugin mechanism. GitHub repository is here .
