Hi,
In my local I have created 3 brokers (IIB v10) , 2 associated with QM(MQ 7.1) , 1 without QM. Suppose broker A and Broker B are ones which have QM and without QM respectively . In broker C i have logging code deployed . I need to emit monitoring events from applications deployed in Broker A & broker B , which I need to subscribe by local QM in broker C and log eventually.
For Broker A , how can i get subscriptions from Broker C to listed to topics of Broker A and
For Borker B which doesn't have a qm how this scenario will work out.
Thanks |

To use monitoring events, you either need an MQ topology for the events or an MQTT topology. It's for this reason an MQTT broker is supplied is built into versions of IIB/ACE that don't require a queue manager.

| For non QM broker will work on your suggestion , but for Broker A which has a QM , so do i need to use remote Queues to get its events being subscribed by Broker C |

You need to follow the standard practice for a mixed MQ / MQTT environment. Or use MQTT for all the events, even for those brokers blessed with a queue manager.

For Brokers which have QMs , I have added both the queue managers in a cluster created via MQ explorer . Now I have created a topic in QM A and subscribed it using a subscription in QM B , but while testing publication , not able to get the message published in QM A , in the local queue of QM B which has been defined in the local subscription .
AM i missing something here . |

I have figured out the issue is happening when I am using a topic string with $SYS/Broker/IIB10/Monitoring/egname/# in QM A
However when I am using a topic such as /Cricket I am able to subscribe it with the other QM B |

Hi,
I have enabled monitoring on the IIB flow by using mqsichangeflowmonitoring command
Since this is flow is deployed in a broker which doesn't have a Q manager , I have also used
mqsichangeproperties IBNODE -b pubsub -o BusinessEvents/MQTT -n enabled -v true
Further I've setup a flow with a MQTT Subscriber node on the topic on a different broker which has a QM on the topic
IBM/IntegrationBus/IBNODE /Monitoring/default/#
When i trigger the message flow to emit events I am not able to capture it on the other flow deployed a different broker with MQTTsUSRIBER NODE . |

What happens when you subscribe with a topic of /#?
What are the published topics names on the events you collect with such a subscription?

| I was able to get subscription , the issue was with topic name i had used the wrong broker name . However is there any way in which I can avoid using MQTTSubscriber node and use a subscription form non QM broker to a queue in other broker which has MQ . |

See here, here, here, here, here,here and about a dozen other links Mr. Google found me when I asked about mixing IBM MQ with MQTT.

I followed the link , https://www.ibm.com/support/knowledgecenter/SSFKSJ_9.0.0/com.ibm.mq.pro.doc/q002940_.htm
for Publishing a message to IBM MQ from an MQTT client
Folllowed the steps and created a subscription with topic string
on the QM of broker B :
IBM/IntegrationBus/IBNODE /Monitoring/default/#
and enabled event monitoring on broker A
mqsichangeproperties IBNODE -b pubsub -o BusinessEvents/MQTT -n enabled -v true
Still not able to get events on the queue of broker B |

Then you have a communication problem, don't you?
