Linux Shell 脚本监控 WAS (WebSphere Application Server) 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"
WSADMIN="/opt/IBM/WebSphere/AppServer/bin/wsadmin.sh"
FILE_STAT_LOG=was_stat_`date +"%Y%m%d_%H%M%S"`.log
$WSADMIN -lang jython -host $WAS_IP -user $WAS_USERNAME -password $WAS_PASSWORD -f check_was_state.py > $FILE_STAT_LOG 2>&1

grep "${WAS_INSTANCE_NAME}: STARTED" $FILE_STAT_LOG > /dev/null 2>&1
if [ $? == 0 ]; then
    echo "$WAS_IP $WAS_INSTANCE_NAME status is OK"
else
    echo "$WAS_IP $WAS_INSTANCE_NAME status is not OK"
fi
