1.python的脚本如下:

ColletRuntime.py

2.将脚本放到weblogic的安装目录D:weblogiceawlserver_10.3commonin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:weblogiceawlserver_10.3commonin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)Javajdk1.6.0_10in

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. hogging  thread 和 busy thread都是找出最大值即可

至此,监控过程全部完成。
