Capacity Analysis, Tuning, and Review
The monitoring systems, in cloud environments, carry out ongoing health checkups and keep generating monitoring data that requires in-depth analysis in order to derive meaningful information. This chapter explains the analysis of monitoring data and how this analysis helps in tuning the capacity in order to facilitate performance optimizations. Statistical algorithms are explained; these carry out the capacity analysis for trending and forecasting. The later parts of the chapter describe the capacity management review, which aims to improve the capacity management process itself. Key performance indicators (KPIs) are defined for the cloud capacity management process. The KPIs act as process performance metrics. Capacity reports that must be generated are also explained in this chapter.
