使用python脚本监控weblogic

1.python的脚本如下：

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 ，其中的4556为服务器的进程号。通过jconsole查询得出。

3. 在输出的结果中，可以看到full gc的输出结果。

至此，监控过程全部完成。
