Summary

Any performance or capacity analysis begins with a concise description of the performance problem in terms of something that can be measured. Taking a look at the overall system is an essential starting point, because it provides an understanding of the system and workload profile that may make your path to the root cause much shorter and/or may uncover other issues that might not otherwise have been visible. This chapter was intended to provide a starting point for your work with DTrace. Use the remaining chapters in this book for more detailed observability and to drill down into specific areas.
