Activity Monitor Instrument

活动监测仪器Activity Monitor Instrument

Overview

Instrument Description	The Activity Monitor instrument captures information about the load on the system measured against the virtual memory size. It can record information from a single process or from all processes running on the system.

Timeline Pane

时间轴窗格根据仪器的配置显示以下列表中显示的信息。totalvmsize，cputotalload，cpuuserload，和cpusystemload默认显示。在“检查”窗格中的“记录设置”区域中启用其他统计信息。The timeline pane displays the information shown in the following list, based on the instrument’s configuration. TotalVMSize, CPUTotalLoad, CPUUserLoad, and CPUSystemLoad are displayed by default. You enable additional statistics in the record settings area in the inspector pane.

Record Settings

单击记录设置”按钮在检查面板自定义以下记录选项。Click the Record Settings button () in the inspector pane to customize the following recording options.

采样率Sampling Rate

设定仪器记录信息的频率。滑块允许在1 /第十的第二到1秒的第二增量1 /第十采样。文本字段允许其他1 /第十增量。默认值是秒的1 /第十。Set how often the instrument records information. The slider allows sampling from 1/10th of a second to 1 second in 1/10th of a second increments. The text field allows for other 1/10th increments. The default value is 1/10th of a second.
