Linux Shell 指令碼監控 WAS (WebSphere Application Server) 的運行狀態

Linux Shell 指令碼監控 WAS (WebSphere Application Server) 的運行狀態
原理：通過調用 WAS 內建的指令碼 wsadmin.sh 來擷取執行個體的狀態

作業系統版本：

[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

代碼：

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

# List servers with specified server type

if (len(runningServer) > 0):

  
serverState = AdminControl.getAttribute(runningServer, "state")

  
else:

# endIf

  
# Two different states: STARTED, STOPPED
