MQSeries.net :: View topic - Configure IIB's MQTT brk Subscription to be highly available

--> Requirement
Use IIB's monitoring profiles/events for capturing logging/auditing information from IIB apps
Configure system in such a way that no events are dropped by consuming clients.

--> Context
My environment has multiple IntegrationNodes in it. These IIB nodes doesnot have an WMQ queue-manager associated with it.
Monitoring events will be published to IIB's inbuilt MQTT broker.
IIB application with MQTT subscription node is used to consume events published to topic [IBM/IntegrationBus/+/Monitoring/#]
IIB version : 10

--> My solution
I plan to deploy Monitoring Events Consuming MQTT Subscription APP to each broker in two execution groups. One ExecutionGroup will have app in active state and other ExecutionGroup will have app in stopped state. Both apps will use same MQTT Subscription policy with same client id.
My intention is that even if one of the execution groups goes into inactive state, then a manual action can be taken to start the mqtt subscribing app in other execution group. This is a temporary work around involving manual action until the faulty EG is brought back online.

--> Constraints that I am working with
I donot have an external MQTT broker.
I prefer to use IIB to consume monitoring events
APM can be used to script and run automation tasks.

-->
I seek your thoughts on configuring a highly available system where no events from mqtt topic are lost by the consuming iib client
