This document discusses monitoring and capacity planning on a consolidated environment. It begins with comparing CPU speeds using benchmarks like TPC-C and SPECint_rate2006 or tools like cputoolkit and SLOB. It then covers cores vs threads, explaining how hyper-threading can increase performance by around 30%. Different CPU events like CPU utilization, wait, and scheduling are also explained. Finally, it discusses monitoring CPU usage on consolidated environments using operating system tools like vmstat, top, and mpstat.
