Jython-скрипт для проверки статуса приложения на каждом сервере в кластере

Опубликовано 27.12.2014 Автор: Sergey Kirsanov — Комментариев нет

Иногда административная консоль WebSphere Application Server неправильно отображает статус приложения. Требуется установить статус приложения на каждом сервере в кластере. Для этого можно использовать jython-скрипт, на вход которого будет передаваться два параметра – имя приложения и имя кластера.

import time
from sys import argv

def appStatusOnClusterMember ( clusterName, appName ):

     global AdminControl
     global AdminConfig

     clusterID=AdminConfig.getid('/ServerCluster:'+ clusterName +'/')
     clusterList=AdminConfig.list('ClusterMember', clusterID)
     servers=clusterList.split('\n')

     for serverID in servers:
                serverName=AdminConfig.showAttribute(serverID, 'memberName')
                #  Prints Only Running Cluster Members
                aServer = AdminControl.completeObjectName('type=Server,name=' + serverName + ',*')
                if aServer == '':
                    print ''
                    print 'Server', serverName, 'is DOWN. Please, start the server.'
                else:
                    aState=AdminControl.getAttribute(aServer, 'state')
                    print ''
                    print 'Server', serverName, 'is in a', aState, 'state'
                    appStatus = AdminControl.queryNames('WebSphere:type=Application,name='+appName+',process='+serverName+',*')
                    if appStatus == '':
                         print 'Application', appName, 'is NOT RUNNING on', serverName
                    else:
                         print 'Application', appName, 'is RUNNING on', serverName
                    #Endif
                #Endif
     #Endfor

# check the status on each server
appName = sys.argv[0]
clusterName = sys.argv[1]
print '================================================================================='
print 'Cluster', clusterName
print '================================================================================='
appStatusOnClusterMember( clusterName, appName )

import time

from sys import argv

def appStatusOnClusterMember ( clusterName, appName ):

global AdminControl

global AdminConfig

clusterID=AdminConfig.getid('/ServerCluster:'+ clusterName +'/')

clusterList=AdminConfig.list('ClusterMember', clusterID)

servers=clusterList.split('\n')

for serverID in servers:

serverName=AdminConfig.showAttribute(serverID, 'memberName')

# Prints Only Running Cluster Members

aServer = AdminControl.completeObjectName('type=Server,name=' + serverName + ',*')

if aServer == '':

print ''

print 'Server', serverName, 'is DOWN. Please, start the server.'

else:

aState=AdminControl.getAttribute(aServer, 'state')

print ''

print 'Server', serverName, 'is in a', aState, 'state'

appStatus = AdminControl.queryNames('WebSphere:type=Application,name='+appName+',process='+serverName+',*')

if appStatus == '':

print 'Application', appName, 'is NOT RUNNING on', serverName

else:

print 'Application', appName, 'is RUNNING on', serverName

#Endif

#Endfor

# check the status on each server

appName = sys.argv[0]

clusterName = sys.argv[1]

print '================================================================================='

print 'Cluster', clusterName

print '================================================================================='

appStatusOnClusterMember( clusterName, appName )

Для того, что бы было удобно вызывать этот jython-скрипт, напишем bash-скрипт:

#!/bin/bash
echo "================================================================================="
echo "This script show an application status on each member of cluster"
echo "================================================================================="
echo "Please, enter an application name:"
read appname
echo "================================================================================="
echo "Please, enter a cluster name:"
read clstrname
echo "================================================================================="
echo "Starting wsadmin tool..."
echo "=================================================================================" 
cd /opt/ibm/WebSphere/AppServer/profiles/dmgr/bin
./wsadmin.sh -conntype SOAP -host localhost -port 8879 -lang jython -user username -password password -f /home/brateserj/scripts/AppStatus.py $appname $clstrname

#!/bin/bash
