我们将讨论其他的性能监控和调优技术、Design Advisor的使用、活动监控器、表快照函数和其他工具。
We will discuss other performance monitoring and tuning techniques, and the use of the Design Advisor, the activity monitor, table snapshot functions, and other tools.
快照监控器允许您捕获特定时间内数据库活动的状态，而事件监控器只在特定数据库事件发生时记录数据。
The snapshot monitor enables you to capture a picture of the state of the database activity at a specific moment in time, while event monitors log data only as specified database events occur.
监控器数据收集应该包含一个时间框架，您期望在这段时间内发生普通数据库活动(例如，每个工作日的9 a . m .到5 p. m.)。
Your collection of monitor data should cover a time frame in which you would expect normal database activity (for example, between 9 a.m. and 5 p.m. during a workday).
