HOW'S YOUR MEMORY

摘要

Detailed memory analysis of a system, especially a large complex system, can be very beneficial. The analysis may uncover performance issues or misuse of this limited system resource. Obtaining the analysis data though is often difficult. This paper describes how SAS uses RootCause along with a custom probe to gather data from the SAS System memory management routines. The type of data collected will be described, along with the types of problems that can be uncovered by analyzing this data.
