Get count of JMS Queue Messages using Automation Script

• Maximo use JMS queues for inbound, outbound data processing. These messages and message count can be manually viewed from External System application.
• Here is a simple automation script to get the count of Messages in JMS Queues. It  can be used in Action Launch point to view message count in 'Action button' of an application  OR in an Escalation to send details via Email.

Script:

from psdi.iface.jms import JMSQueueBrowser

from psdi.iface.jms import MaxQueueCache

from psdi.iface.jms import QueueConfig

from psdi.iface.jms import JMSData

qbrowser = None

queueName = "jms/maximo/int/queues/cqin"

selector = "SENDER='ABC'"

config = MaxQueueCache.getInstance().getQueueConfig(queueName);

connectionFactory = config.getConfactName();

env = config.getEnv()

qbrowser = JMSQueueBrowser(queueName, connectionFactory, selector, env);

qList = qbrowser.getAllMessages();

qCount=len(qList)

#raise TypeError("Messages Count - "+str(qCount))

print '-- Number of Messages in the Queue : ' +str(qCount)

Script Variables:

queueName = path of the JMS queue as configured in Maximo

selector = condition to filter the Queue Messages (https://www.ibm.com/docs/en/cdfsp/7.6.1.x?topic=configuration-viewing-deleting-messages-in-jms-queue)
