Windows BAT 脚本监控 WebLogic 的运行状态、健康状态、打开的套接字数

经常看到有人通过检查 PID 或者端口号是否存在来判断 WebLogic 实例是否正常。

其实那种方法是不好的。因为在实际的线上环境里面，WebLogic 实例会因为很多种原因出现异常，比如内存溢出、过载、死锁等，这个时候它的 PID 或端口都没有问题，但实际上它已经无法正常工作了，需要通过重启 WebLogic 实例才能恢复正常。

一个更加靠谱的监控方法是，在脚本里面调用 WebLogic 的命令 weblogic.Admin 来判断实例的状态。希望本文的脚本对大家有所帮助。

操作系统版本：

C:\>systeminfo | findstr /c:"OS Name"
OS Name:                   Microsoft(R) Windows(R) Server 2003 Enterprise x64 Edition

WebLogic 版本：

C:\>java weblogic.version | findstr "WebLogic"
WebLogic Server 10.3.6.0  Tue Nov 15 08:52:36 PST 2011 1441050
