Monitors were not created because CompleteTopologyEvent was published before AutoscalerComponent was activated. In the attached logs,
Line number 478 - CompleteTopologyEvent was received by AS Line number 501 - AutoscalerComponent was activated When AS received CompleteTopologyEvent, it didn't load the application context from registry. Hence it just logged "The application is not yet deployed for this [application] asdevelopment" (Line number 482) and ignored the CompleteTopologyEvent. And CompleteTopologyEvent is published only once (until topology is initialized) - so there is no way that the monitors will be created. It needs to be fixed. Thanks, Raj.
