There is a plethora of z/OS performance metrics available. Some are easily understood and their applicability is well-known. Others are not so obvious. The more difficult question can be “what is a good value for this metric?â€? For some metrics, there are no “rightâ€? or “wrongâ€? values as they are workload-dependent, but it is still interesting to understand the range of values commonly seen. Situations that generate metrics outside the normal range might be worth investigating. Some metrics have old rules-of-thumb that might not be valid today.
Join Scott Chapman for a tour through some interesting z/OS performance metrics, both familiar and not-so-familiar. He will provide a sense for what values other customers are seeing for these metrics as well as some modern rules of thumb where applicable.-Scott Chapman-Enterprise Performance Strategies Inc.
