ColletRuntime.py 2.将脚本放到weblogic的安装目录D:\weblogic\bea\wlserver_10.3\common\bin下
3.修改collectionRuntime.py中的weblogic的用户名，密码，IP,端口，日志路径修改成正确的数据。
4.打开CMD窗口，切换到D:\weblogic\bea\wlserver_10.3\common\bin下，然后执行命令wlst.cmd CollectRuntime.py
5.在日志路径下会看到自动生成的CSV文件。能看到HoggingThread和busyThread的数据。
监控gc执行情况的方法如下：
1. 首先需要安装jdk,在jdk/bin目录下，例如：C:\Program Files (x86)\Java\jdk1.6.0_10\bin
2. 打开CMD窗口，切换到jdk/bin目录下，使用命令jstat -gcutil 4556 5s 100 >d:/jstat/text.log ，其中的4556为服务器的进程号。通过jconsole查询得出。
使用 > d:/jstat/text.log的方式可以将jstat的输出结果保存到文件中。
3. 在输出的结果中，可以看到full gc的输出结果。
4. 在监控full gc和hogging thread的过程中，adminserver是不用监控的。
计算方法：
1. full gc间隔，使用FGC列计算，最后一项减去第一项，除以场景时间（分）。
2. gc执行时间，使用FGCT列计算,最后一项减去第一项，除以场景的执行时间（秒）。
3. hoggingthread 和 busy thread都是找出最大值即可
至此，监控过程全部完成。
