This article explores how to monitor and analyze memory usage in SQL Server 2005 x64, focusing on using Perfmon to check key metrics such as Target Server Memory and Total Server Memory. It addresses common issues like memory leaks and paging file usage, providing monitoring steps, solutions, and best practices to help users effectively manage SQL Server memory resources.

This paper provides an in-depth technical analysis of monitoring historical CPU and memory usage for specific processes in Windows systems. Through detailed examination of Performance Monitor (perfmon) core functionalities, it presents comprehensive configuration procedures for counter logs to record process performance data. The study contrasts auxiliary tools like Process Explorer and incorporates cross-platform monitoring insights from Linux environments. Programmatic implementation principles and practical application scenarios are thoroughly discussed, offering system administrators and developers a complete reference for performance diagnostics and optimization strategies.

This article provides an in-depth analysis of the root causes of SQL Server high CPU load and practical solutions. Through systematic performance baseline establishment, runtime state analysis, project-based performance reports, and the integrated use of advanced script tools, it offers a complete performance optimization framework. The article focuses on how to identify the true source of CPU consumption, how to pinpoint problematic queries, and how to uncover hidden performance bottlenecks through I/O analysis.

This article provides a comprehensive examination of three critical memory metrics in Windows systems: private bytes, virtual bytes, and working set. It explores their definitions, interrelationships, and practical applications in memory leak debugging. By analyzing the underlying mechanisms of these metrics, the article reveals their limitations in memory usage assessment and offers more effective tools and methods for memory leak detection. Through concrete examples, it helps developers accurately understand process memory usage and avoid common diagnostic pitfalls.
