Chapter Four. System Performance Monitoring
By Gerrit Huizenga, Peter Wai Yee Wong, and Vaijayanthimala Anand
This chapter focuses on tools that initially help monitor the overall performance of the system. After the overall system performance characteristics of a workload are understood, the same tools can be useful in identifying which particular processes are bottlenecks to the overall workload. In many cases, the system monitoring tools can help drive system tuning such that the key bottlenecks can be substantially reduced or eliminated. In other cases, these tools simply pinpoint applications or processes that need tuning, reconfiguration, or, in the most extreme case, algorithmic changes to improve overall workload performance ...
