收集SQL Server统计信息
问：我需要在运行SQL Server的机器上定期收集诸如每秒处理事务数（tps）之类的统计信息。为此，我大量使用了Performance Monitor（性能监视器），但却不能得到DBA所需的SQL Server性能指标。请问是否存在能够轻松收集这类统计信息的实用工具？
答：针对SQL Server的Performance Monitor计数器之一便能收集tps，因此，使用Performance Monitor是捕获这项指标最便捷的方式。您可以通过Microsoft Windows® NT Server 4.0 Resource Kit或Microsoft Windows 2000 Server Resource Kit以服务的形式安装Performance Monitor。此外，我建议您阅读Steve Adrien DeLuca等人所著的《Microsoft SQL Server 7.0 Performance Tuning Technical Reference》以学习关于测试有用SQL Server性能数据的内容。
