This paper extends the methodology presented in 2013—Capacity Analysis Techniques Applied to VMware VMs (aka When is a Server not really a Server?—to include deeper CPU analysis, compared with Memory analysis in 2013). This paper demonstrates a holistic approach that defines and analyzes the relevant group of metrics from each layer of the virtualization, i.e. ESX cluster, host, VM, the VM’s operating system (Linux or Windows), and the application to determine if the guest needs to be resized or the ESX environment requires changes. For 2013, there is both a formal paper and a presentation. For 2018, the presentation is complete and I’m expecting to complete a formal paper as well.
The Computer Measurement Group is a not-for-profit, worldwide organization of IT professionals committed to sharing information and best practices focused on ensuring the efficiency and scalability of IT service delivery to the enterprise through measurement, quantitative analysis and forecasting. CMG members are primarily concerned with performance evaluation of existing systems to maximize performance (eg. response time, throughput, etc.) and with capacity management where planned enhancements to existing systems or the design of new systems are evaluated to find the necessary resources required to provide adequate performance at a reasonable cost.
