Is My z/VM System Full?

From time to time customers ask us whether their z/VM systems are "full." In other words, can the system absorb any more work? Does it have any capacity remaining? Could I do more with my system without adding hardware? Answering this question requires looking at the capacity and
utilization of each of a number of different physical resource types. For example, how much CPU capacity is there, and how utilized is it? The same questions can be asked about memory, I/O, networking, and ISFC links. In this presentation we use z/VM Performance Toolkit ("Perfkit") screens to explore systems' physical resource capacities and utilizations in a number of different categories of resource. Sample screen shots illustrate which Perfkit screens to consult, which columns are especially helpful, and what values in those columns represent "full."
