Linux Shell脚本监控WAS的运行状态

Linux Shell脚本监控WAS的运行状态

原理：通过调用 WAS 自带的脚本 wsadmin.sh 来获取实例的状态

操作系统版本：

[root]# head -1 /etc/redhat-release Red Hat Enterprise Linux Server release 5.3 (Tikanga)

WAS 版本：

[root]# /opt/IBM/WebSphere/AppServer/bin/versionInfo.sh | grep -A 3 "Installed Product" Installed Product -------------------------------------------------------------------------------- Name IBM WebSphere Application Server - ND Version 7.0.0.25

代码：

check_was_state.sh

#!/bin/ksh  
WAS_IP="192.168.222.3" 
WAS_USERNAME="wasadmin" 
WAS_PASSWORD="wasadmin" 
WAS_INSTANCE_NAME="SampleServer1"

FILE_STAT_LOG=was_stat_`date +"%Y%m%d_%H%M%S"`.log

else
