WAS JMS Listener Status wsadmin

In environments where you have more usage of WAS JMS services  and  integration with Websphere MQ and MB. We might be in the need to look after the  JMS listener status, always.

If the Listener status  is "false"  it means that your listener is not picking/writing messages from/to the Queue.

Before we end up in the backlog. Its always  recommended to have one listener status monitoring  which should/could intimate you in case of  abrupt  failure (or) stoppage in listener.

Here is the wsadmin Jython Script which will let you know the status of WAS Listeners under the Cell.

Jython code

import re
Running_Nodes=AdminControl.queryNames('*:type=Server,name=nodeagent,*').split(java.lang.System.getProperty("line.separator"))
print "----------------------------------------------------------------------------------------------"
print "Websphere Listener Status Report for the Cell", AdminControl.getCell()
cell=AdminControl.getCell()
print "----------------------------------------------------------------------------------------------"
print ""
print ""
for nod in Running_Nodes:
        NodeName=AdminControl.invoke(nod ,"getNodeName()")
        Running_JVMS=AdminControl.queryNames('*:type=Server,node='+NodeName+',*').split(java.lang.System.getProperty("line.separator"))
        for Serv in Running_JVMS:
                ServerName=AdminControl.invoke(Serv,"getName()")
                Listener_Ports=AdminControl.queryNames('*:type=ListenerPort,cell='+cell+',process='+ServerName+',*').split(java.lang.System.getProperty("line.separator"))
                if Listener_Ports == ['']:
                        break
                else:
                        print ""
                        print ">>Server %r Running at %r"%(AdminControl.invoke(Serv,"getName()"),NodeName)
                        print "----------------------------------------------------------------------------------------------"
                        print "Name\tJNDIName\tDestiationQueueName\tAvailable"
                        print "----------------------------------------------------------------------------------------------"
                        for lis in Listener_Ports:
                                JNDIName=AdminControl.invoke(lis,"getJmsConnJNDIName()")
                                DestName=AdminControl.invoke(lis,"getJmsDestJNDIName()")
                                match=re.search(r'([:\w]+)=([\w]+)',lis)
                                name=match.group(2)
                                state=AdminControl.invoke(lis,"isStarted()")
                                print "%r\t%r\t%r\t%r"%(name,JNDIName,DestName,state)
                print "----------------------------------------------------------------------------------------------"

Note on compatibility:

WAS6.1 and above as it has REGEX usage.

Result

--------------------------------------------------------------------------------------
Websphere Listener Status Report for the Cell MWICell

You can have a shell script on top of it which would trigger alert email in case of any "false" in the Available status.

Here is the sample shell script to send email notification. ( Make sure you have valid mail setup in your server with dummy mail before setting this up)

Environment Setup:  

• Create a directory in your server and copy all these script files (.py file and .sh file).
• Make sure you have full access on that directory as the script will be creating some temp files for processing.

Shell script

#!/bin/sh
BASEDIR=`dirname $0`
/apps/websphere8/mwi/bin/wsadmin.sh -conntype SOAP -host MWICell -port 8834 -user wasadminusr -password wasadminpass -lang jython -f $BASEDIR/listenerstatus.py > report

RECIPIENTS="sara@mwinventory.in"

grep -i "false"  $report > $BASEDIR/outfile

if [ $? -eq 0 ]
then
    echo "Hi Team" >> $BASEDIR/outfile
    echo "" >> $BASEDIR/outfile
    echo "Below Listeners are seem to be notrunning or stopped, Please check the status and restart the JVM if required." >> $BASEDIR/outfile
    echo "" >> $BASEDIR/outfile
    mailx -s "ALERT: Listener Status Stopped" $RECIPIENTS < $BASEDIR/outfile
fi

As usual let me know your queries by comments.

Hope it helps.

Cheers,
