If I use this in my server yaml, I can publish monitoring events to a remote queue manager using ccdt.

BusinessEvents: # Monitoring events
    MQ:
      policy: '{MQEventLogPolicy}:MQCCDT'                # Specify a {policy project}:policy if not using  'defaultQueueManager'
      enabled: true            # Set true or false, default false
      format: ''                # Set string or none
      outputFormat: 'xml'       # Set comma separated list of one or more of : json,xml. Defaults to 'xml'

but when I change the format to json, I get the error.

BusinessEvents: # Monitoring events
    MQ:
      policy: '{MQEventLogPolicy}:MQCCDT'                # Specify a {policy project}:policy if not using  'defaultQueueManager'
      enabled: true            # Set true or false, default false
      format: ''                # Set string or none
      outputFormat: 'json'       # Set comma separated list of one or more of : json,xml. Defaults to 'xml'

An error occurred publishing integration node event on topic '$SYS/Broker/integration_server/MonitoringEvents/JSON/is2/EIL_Loopback_APP/HTTP_LoopBack_Monitoring_Flow' using the 'MQ' transport. 
: BIP2666E: Unable to open queue '$SYS/Broker/integration_server/MonitoringEvents/JSON/is2/EIL_Loopback_APP/HTTP_LoopBack_Monitoring_Flow' on IBM MQ queue manager '*LOGSVCS': completion code 2; reason code 2035. 

What could be the reason??

subscription are defined for topicstring - $SYS/Broker/integration_server/MonitoringEvents/JSON/is and $SYS/Broker/integration_server/Monitoring/is, pointing to different queues. 

Hi,

mqrc 2035 = MQRC_NOT_AUTHORIZED.

Did you check the mq error logs (/var/mqm/qmgrs/<qmgr>/errors)? These will probably show what the authorization error is.
