请在PerfMon窗口上方的工具栏中单击+按钮，这样会打开一个对话框让您选择要监控的计数器，如图3a所示。

To get going, click on the + button on the toolbar at the top of the PerfMon screen. This brings up a dialog that lets you choose the counters you want to monitor, as in Figure 3a.

如果标题栏(监控本身)的提示不够清楚，注意您刚打开的第二个JConsole窗口，它监控JConsole应用程序本身。

If the title bar (monitoring self) isn't hint enough, notice that the second JConsole window that you just opened is monitoring the JConsole application itself.

在打开合适的监控器开关之后，您可以在同一db2命令窗口使用GET SNAPSHOT命令来收集监控统计信息。

After the proper monitor switches are on, you can use the GET SNAPSHOT command from the same DB2 command window to collect monitoring statistics information.
